Sensors may only be connected and disconnected when the device has been switched off. All ALMEMO® sensor generations (V5, V6 sensors, as well as D6 and D7 digital sensors) can be arbitrarily connected to the ALMEMO ® input sockets. The comprehensive ALMEMO® sensor program and the option to connect your own sensors to ALMEMO® devices is described in detail in the ALMEMO® Manual (see ALMEMO® Manual chapter 3 and chapter 4). All standard sensors with ALMEMO ® plugs are generally programmed with measuring range and dimension and can therefore readily be connected to every input socket. 10.2.1. Measuring inputs and auxiliary channels In the standard configuration, the measuring instrument ALMEMO® 500 features 20 input sockets (per measuring circuit board M0 to M9) to which primarily the measuring channels M000_0 to M009_0 (measuring circuit board 1) and M010_0 to M019_0 (measuring circuit board 2) are allocated. Since standard sensors (V5, V6, D6, and D7) can offer – if needed – up to 4 channels and D7 sensors even a maximum of 10 channels, the channel assignment displayed in Figure 4 results. In this case, the allocation of V5 and D7 sensors to the input sockets is exemplarily illustrated. Figure 4 - 18 - Channel assignment and numbering of the ALMEMO® 500 10.3.

Line graph As soon as a measurement is started, the data logger initiates a cyclic measured value recording (the scanning and memory cycle can be configured in the data logger settings; please refer to chapter 11.6.2 on this topic). After the measurement has been started, the line graph is filled with measured data. By default, i.e. after starting the application, every measuring channel is displayed as a line. Thereby, the display mode is set to “Total measurement”. • Integrated sidebar featuring different display modes Via the integrated sidebar, which you can open by clicking on the symbol in the upper right area of the line graphics, you can switch between the different display modes (manual, automatic and total measurement). The measuring display “Line graphics” together with the sidebar is displayed in the following figure. You will find further information regarding the sidebar and its functionality in chapter 11.3.2.7 Figure 12 Line graphics - 41 - • Loading recorded (historic) measurements In case you want to display older (historic) measurements from the memory as a line graphics, you can either export the measurement (in a CSV format, see chapter 10.5) and open the data in Excel or you can request the measurement directly from the data logger and display it in the application (see Figure 13). It is also possible to load a historic measurement during an ongoing measurement. When loading a measurement, the local measured data storage on the tablet is overwritten with the historic measured values. After the historic measurement has been closed, the line graphics of the current measurement starts over again. The data saved to the measured data storage on the data logger remains unchanged. To display a saved measurement, press the button “Load measurement” in the sidebar and then select the measurement you want to load from the list. Confirm the process by pressing the button “Load”. By pressing the “Back” button, you will return to the line graphics. In doing so, the historic measurement will be closed and the measured values will be deleted locally respectively will be overwritten with the current measurement.

Channel selection Axes allocation Date/time format In the drop-down menu in the column “Channel”, you can select the measuring channels that shall be displayed. Via the drop-down menu in the column “Axis”, you can allocate the measuring channels to one of the two Y-axes and determine a dimension for both axes. Via the arrow buttons in the footer of the settings menu, you reach another configuration menu, where you can define the date format to be used in the line graphics. • Save settings You can apply and save all configurations effected in the settings menu by pressing the button “Save settings”. If you exit the menu via the “Back” button, all settings made will be lost. - 43 - Figure 14 • Line graphics settings Selection and scaling of the Y-axes Having activated two Y-axes, you can scale the time and the Y-axes either singly or combined via the integrated swipe gesture control (2 fingers swipe gesture). For this purpose, the following swipe gestures were implemented. Zoom into the time axis Zoom out of the time axis 1) 2) 1) Zoom out of the Y-axis (axes) 2) Zoom into the Y-axis (axes) 1) 2) 1) Zoom out of the time and the Y-axis (axes) 2) Zoom into the time and the Y-axis (axes) You can find further information regarding swipe gesture control on Android on the Internet. If you only want to scale one of the two Y-axes, you have to • switch the mode to “Manual” in the sidebar • then tap on the Y-axis you want to scale. - 44 - After tapping on it, the desired Y-axis is marked black (see Figure above). By using swipe gestures, you can now scale the selected Y-axis singly, whereby the scaling of the second Y-axis remains unchanged. Tapping in the line graphics or switching in an automatic mode (automatic or total measurement) will terminate the selection mode. It is only possible to individually scale the time and/or the Y-axes in the “Manual” mode. Also marking respectively selecting axes is only possible in the “Manual” mode! 11.4.4. User menu If you need an individual measured value display tailored to your measuring task, you can realize this via the measuring display user menu. You can choose among three predefined user menus (templates) and freely configure up to 12 measured values on one page. The following user menu templates are available: 2 columns, each with 6 small cells 2 columns, each with 4 small and 1 large cells - 45 - 2 columns, each with 2 small, 1 middle, and 1 large cells To configure a user menu, click the tab “User menu” in the measuring display menu. Via the “Add” button, you can choose a template and assign a name to your individual user menu. Then create the user menu by tapping on the “Add” button. Now an empty template appears that you can individually fill with measuring channels and your desired measurement functions (see Figure 15). After having chosen the desired parameters, you can save your entry by tapping on the “Set cell” button. Repeat these steps for the following cells. The settings will be saved locally on the control unit and can be retrieved under the specified template name at any time. The content of occupied cells can be deleted by using the function “Empty cell”. Afterwards, the cell can be filled again. Via the button, you can delete user menus you have created earlier.

Memory The following functions are available in the data logger display menu. • - Memory condition Memory status: Entire memory: Memory free : Save mode: Shows the occupied memory in percentage. Shows the total size of the measurement memory. Shows the memory that is currently free. Ring memory active Linear memory active • Setting There are two save modes, ring memory and linear memory. In the ring memory mode, old data is overwritten as soon as the memory is full. In the linear memory mode, the measurement stops as soon as the memory is full. The memory is automatically set to ring memory mode as long as only one measurement is saved to the memory. Consequently, the ring memory mode requires erasing the measurement memory first. In case other measurements are already saved to the memory when a new measurement is started, the memory will automatically be set to linear memory. • Measurement condition File name Here, an individual file name can be entered. New measurements with the same name will be provided - 47 - with a suffix (e.g. ALMEMO500~1). - Measurement active since: Estimated duration: - • Manage measurement • Export measurements Corresponds to the start time of the measurement. Specifies the extrapolated remaining duration (corresponding to the current system configuration) until the memory is full. In this window you can view, select (single or all measurements), and delete measurements. Additionally, name, period, and size of the measurement are displayed. To export a measurement, select the tab “Export” and continue with “Export measurements”. In the following, select the measurement and press the button “Export measurement” in the footer of the current tab. A new window will open, where you can select the storage location (internal memory or USB) (see the following Figure). Figure 16 Window “Export measurement” Start the measurement export by pressing the “Export” button. The measurement will now be exported. The progress (in percentage) is shown in red in the message line below the footer. - 48 - • Delete exported measurements If you want to delete an exported measurement, you need to select the option “Delete exported measurements” in the Export tab. A new window will open, in which you can select exported measurements (singly or all measurements) and remove them from the memory by pressing the button “Delete export”. Pressing the “Back” button will bring you back to the “Data logger” menu. Device-specific data logger settings e.g. conversion rate or memory cycle are described in chapter 11.6.2. 11.5.1. Start and stop measurements Besides being able to start and stop the cyclic measurement by using the buttons Start and Stop or the interface (see Manual 6.6), there is a number of other options, such as start/stop time and date, fixed measuring period, or the limit value actions. After a measurement has been started (LED START on the front panel of the CPU card lights), no further programming is possible. It is not permitted to reconnect the sensors, i.e changes will not be recognized and therefore not be evaluated. 11.6. Settings The “Settings” menu provides the opportunity to adjust the settings on the data logger, on single devices (measuring circuit boards), or on the sensors. The following settings can be read out and configured via the menu. • Device list • Device configuration Sequence control (measuring circuit board) Device settings (measuring circuit board) Device information (measuring circuit board) Sensor overview (measuring circuit board) • Sensor presentation • Sensor channels and channel functions presentation • Sensor configuration Output modules • Sequence control and storage configuration (ALMEMO® 500) • Device settings (ALMEMO® 500) - 49 - • • • Power supply (ALMEMO® 500) Memory status (ALMEMO® 500) Device information (ALMEMO® 500) 11.6.1. Device list The device list lists all devices (plug-in modules) and their corresponding addresses connected to the ALMEMO 500 (see the following Figure). Figure 17 Device list Selecting a device by pressing the > button will forward you to the device settings of the respective plug-in module. 11.6.2. Sequence control (measuring circuit board) Additionally, you can make device-specific settings in the data logger settings menu. Aside from the configuration of memory, scan, and output cycle, this comprises also the configuration of specific start and stop conditions, or of fixed measuring periods for a specific measurement. 11.6.2.1. Cycles • Output cycle After a measurement has been started, the measured values are sent to the interface according to the output cycle or are stored in the memory. The output cycle is programmable between 1s and 59 h, 59 min, 59 s. The cyclic averaging calculation also takes place according to the output cycle after the measurement has been started. • Conversion rate, scan time In the measuring device, respectively on the measuring circuit board, all standard sensors (analog, DIGI) and all digital D6 sensors are continuously measured sequentially at conversion rate; the digital sensors are queried respectively. The conversion rate is programmable to 2.5, 10, 50 or 100 measurement operations - 50 - per second (mops) (total sampling rate). The scan time results from the programmable conversion rate and the number of the active channels of all standard sensors (analog/DIGI) and all digital D6 sensors, including 1 special measurement, and for thermocouples including 2 cold junction measurements. Example: 4 channels are active with standard sensors and D6 sensors (no thermocouples). The conversion rate 10 mops results in a period of 0.1 s per measurement operation. The scan time results from 4 measurement operations each with 0.1 s + 1 special measurement with 0.1 s, in total 0.5 s, i.e. every 0.5 seconds new measured values are available. • Scan cycle The measured values of all standard sensors (analog, DIGI), digital D6 sensors, and digital D7 sensors are recorded within the scan cycle. Each time only new and current measured values are recorded. The highest recording speed can be achieved when the recorded measured values are directly stored in the memory. In doing so a huge number of measured values can be recorded very quickly with the ALMEMO® 500: A measuring circuit board can record up to 2000 values per second, e.g. 4 D7 sensors, 1 channel with a measuring rate of 500 measuring operations per second for each D7 sensor. The scan cycle on the measuring circuit board can at minimum be programmed to 0.002 seconds. In total, the ALMEMO® 500 can record up to 4000 measured values per second, e.g. 8 D7 sensors, 1 channel with a measuring rate of 500 measuring operations per second for each D7 sensor, allocated to 2 measuring circuit boards. The scan cycle on each of the two measuring circuit boards can at minimum be programmed to 0.002 seconds. • Start-, stop modus and measuring period Besides being able to start and stop the cyclic measurement by using the buttons Start and Stop , there is a number of other options, such as start/stop time and date, fixed measuring period, or the limit value actions. • - Using the cycles for different measurements Measurements without digital D7 sensors: The measured values/channels are recorded by the measuring device via the conversion rate – this results in the scan time. For saving cycles greater than/equal to 1 second, the output cycle is used. For saving cycles less than 1 second, the scan cycle is used. The shortest scan cycle is determined by the conversion rate, e.g. for a conversion rate of 10 measurement operations per second, the shortest scan - 51 - cycle is 0.1 seconds. - Measurements with digital D7 sensors only: The measured values are measured in the sensor according to the sensorspecific measuring rate and recorded according to the scan cycle. (Conversion rate and scan cycle are not in use) For saving cycles greater than/equal to 1 second, the output cycle is used. For saving cycles less than 1 second, the scan cycle is used. The shortest scan cycle is determined by the fastest measuring rate (in the D7 sensor), e.g. for a fastest measuring rate of 500 measurement operations per second, the shortest scan cycle is 0.002 seconds. - Measurements with standard sensors (analog, DIGI), digital D6 sensors and digital D7 sensors: Depending on the sensor type, the measured values are recorded according to the procedures described above. With every query, each time only new and current measured values are recorded. 11.6.2.2. Device settings (measuring circuit board) You can perform the following configuration steps in the “Device settings” menu. • Macros You can store 5 macros on the device. Macros are a number of serial commands that can be executed on the basis of trigger events or in case the limit value has been exceeded. The single commands are listed in chapters 6 and 7 of the Almemo ® Manual and each command is separated from the next one by using the character ´|´. The “Macros” menu shows all 5 macros that can be programmed or changed. • Operating parameters In the “Operating parameters” menu, the following features are configurable: • Reduce mains hum: 60Hz instead of 50Hz • As soon as a measurement is started, all maximum, minimum and average values are deleted • Turn the signal transmitter (beeper) on or off • Hysteresis for the exceedance of the limit value (0 – 99 digits, standard 10 digits) • Sensor voltage, setpoint (is automatically derived from the minimal sensor voltage of the sensing device and can be changed to a higher value if required) - 52 - • Device compensation values In the “Device compensation values” menu, three compensation values, which can be measured or programmed, are listed. The atmospheric pressure can be preset for atmospheric pressure compensation. The temperature for compensating a sensor can be set in this menu. To switch off the compensation, the set value must be deleted, i.e. is reset to 25.0°C. The cold junction compensation temperature (CJC temperature) is measured by two precision NTC sensors in the sockets M0 and M9 and is linearly interpolated and used as the cold junction temperature for all thermocouples. The CJC temperature is displayed in the row “CJC temperature”. • Calibration data In the “Calibration data” menu, you will find the serial number and the calibration data of your device. Apart from that, you can enter the next due calibration date and activate a message at the due date. 11.6.2.3. About the device (measuring circuit board) In the “About the device” menu, you will find device-specific information regarding the plug-in module used. Device type and device version, Firmware version, Device option, Serial number 11.6.2.4. Sensor overview (measuring circuit board) In the “Sensor overview” menu, every sensor connected to the device (measuring circuit board) is listed in tabular form showing the following sensor-specific information: Measuring point number, Sensor type, Comment, Firmware version, Serial number From that menu, you can directly access the sensor settings of the selected sensor (see chapter 11.7 – Sensor list and sensor configuration ) by pressing the > key. Via the checkbox at the beginning of the row, you activate or deactivate the sensor. If you - 53 - have deactivated a sensor, the sensor and its corresponding measuring data will no longer appear in the application. 11.6.2.5. Output modules In the “Output modules” menu, the output modules (relay trigger adapter) used with the data logger are automatically detected and listed. Select the desired module and then go to port list and to port settings. There you can configure the function of the single elements (see Almemo® Manual 6.10.9). 11.6.3. Sequence control and storage configuration (ALMEMO® 500) In this menu you can specify the name of the measurement for the current measurement, check the remaining rest of the storage time under “Estimated duration”, configure the location of measurement memory , Attention: Restart is required! edit the measurement memory size. Attention: Restart is required! perform higher-level cycle settings (simultaneously for all devices), retrieve and visualize the cycle settings of all devices (by activating the checkbox “Update cycle data of the devices”). The data logger menu is shown in Figure 18. To edit the parameters, the cyclic measured value enquiry must be stopped. For the location of measurement memory, you can choose between internal (SD card) and external (USB) location. In case you want to use a USB mass storage as an external measurement memory, please connect the USB flash drive to the USB port of the data logger and then select – as described earlier – “External (USB)” as memory location. In consequence, all future measurements are saved to the USB flash drive. (Attention: Restart is required!) The USB port can provide a maximum of 500 mA (5 V). If you connect external hard disks, whose current consumption exceeds 500 mA, you need to use an external mains unit. - 54 - Figure 18 Data logger menu 11.6.4. Device settings (ALMEMO® 500) Under “Settings”, you can adjust time and date of the data logger. Such system parameters can only be adjusted if the measurement has been stopped. Set the desired time by typing on the desired digit and changing the time using the arrow keys. The date on the other hand can easily be adjusted via the integrated calendar function. The data is accepted as soon as you tap outside of the relevant field. Alternatively, you can enter time and date directly in the appropriate fields by using the keyboard. - 55 - 11.6.5. Power supply (ALMEMO® 500) This menu visualizes the parameters of the power supply and of the battery modules (optionally). In this menu, the following information is displayed in tabular form. If no battery module is installed within the system, the unused fields are greyed out and filled with dashed lines. - Expected remaining operating time in battery mode (in hours) Battery status (remaining capacity in percent) Battery voltage in V Charging current/discharging current in A Mains adapter voltage in V Mains adapter current in A 11.6.6. Memory status (ALMEMO® 500) In the “Memory” menu, you will find information regarding the device memory. For detailed information please turn to chapter 11.5. 11.6.7. About the device (ALMEMO® 500) This section includes the following information: - System messages: relevant system and error messages are displayed here Serial number of the data logger Firmware version of the data logger Link to the instruction manual Manufacturer and support information 11.7. Sensor list and sensor configuration In the “Sensor list” menu, all sensors connected to the data logger are listed. The sensors are displayed for each individual device. Via a dropdown menu, you can select one device from all existing devices and show the connected sensors (see Figure 19). - 56 - Figure 19 Sensor list menu Via the checkbox at the beginning of the row, you activate or deactivate the sensor. If you have deactivated a sensor, the sensor and its corresponding measuring data will no longer appear in the application. If you want to change the settings of a sensor (Important: The measurement must have been stopped before doing so), stay in the row of the desired sensor and access the next tier via the arrow keys > (see also chapter 11.6.2.4). 11.7.1. Calibration data In the “Calibration data” menu, you will find information regarding the next calibration and the calibration interval of the sensor. In case the message “Calibration” is activated, the device will notify you by showing a message on the user interface after expiry of the interval. 11.7.2. Sensor channels All sensor channels of the selected sensor are displayed in a list (see the following Figure). Via the checkbox you can deactivate existing sensor channels or define new sensor channels and activate them. Figure 20 Sensor channels menu By accessing the desired sensor channel (via the arrow keys >), you will get to the “Channel functions” menu. - 57 - 11.7.2.1. Channel function Since in every ALMEMO® device the entire sensor programming is saved on the ALMEMO® connector, usually it is not necessary that the user changes any settings in the sensor channels. However, there are a number of setting options available in case sensor errors shall be corrected, your own sensors shall be scaled, or limit values shall be set. The following channel functions are available: • Channel locking In the “Channel locking” menu, you can adjust the locking level of the selected sensor. The function parameters of each measuring channel are protected by an adjustable locking level (see ALMEMO® Manual 6.3.12). Before being able to program, the locking level must be reduced accordingly. If a dot is visible behind a locking level in the display, the locking level cannot be changed. Locking level 0 1 3 4 5 6 7 locked functions none measuring range, plus element flags, plus output mode plus dimension plus zero point correction and gain correction plus base value, factor, exponent plus analog output start and end, and temporary zero setting plus limit values, maximum and minimum • Range selection Normally, all sensor plugs are ready for use when leaving our factory. In case measuring ranges shall be modified or reprogrammed, you can program the desired range via the selection box “Range”. In this menu, it is also possible to enter an individual channel designation and to modify the dimension. To be able to apply any modifications, you must disable the locking function via the checkbox in advance. When entering the new measuring range, standard dimensions and multiplexer are automatically set; however, all programmed values of the channel will be deleted. • Channel designation and function abbreviation On the configuration screen, you can change the channel designation according to your requirements. You can provide every measuring channel with a 10 digit (20 digits for D7 sensor) alphanumerical designation existing of arbitrarily chosen ASCII characters (except for; / | #) to optimally flag the sensor type, the measuring location, or the operational purpose. This designation will be displayed in all measured value - 58 - displays. Several control characters at the beginning of the channel designation have special functions: The following table lists all function abbreviations. ´*J´ ´#J´ ´*T´ ´*P´ ´#N´ defines a temperature sensor (NTC, Pt100) for external cold junction compensation (see ALMEMO® Manual 6.7.3). implies for a thermocouple to use an internal cold junction sensor (e.g. connector ZA9400-FSx with integrated NTC, see ALMEMO® Manual 6.7.3). defines a temperature sensor (NTC, Pt100) as a reference for temperature compensation. defines an atmospheric pressure sensor as a reference for atmospheric pressure compensation. has the following effect for flow measurements: conversion of measurement conditions of temperature compensation and atmospheric pressure compensation to standard conditions. All remaining characters can be used for your individual designation. A ´!´ at the end of a designation implies an individual linearization respectively a multi-point calibration. This cannot be overwritten. Define your desired function by selecting the appropriate function abbreviation via the radio buttons . The correspondent abbreviation will be automatically added to the channel designation. • Measured value smoothing The option of averaging affects exclusively the measured value of the displayed channel and serves to smooth respectively steady measured values by a sliding averaging over a set period of time for fluctuating measured values, e.g. for flow measurements with turbulences. The function “Measured value smoothing” can be adjusted in the range of 0 to 99 according to the number of the values averaged at a time. The smoothed measured value also applies to all following evaluation functions. The smoothing can therefore also be used in combination with the averaging of single measured values. M=(∑ mi)/N i The time constant (s) = smoothing / conversion rate * (V5 channels plus1) is also calculated and displayed in the “Smoothing menu”. - 59 - • Averaging function Please select the “Averaging function” menu. The type of averaging is determined for every channel via the averaging mode function. You can select the desired averaging mode via the checkbox. --- CONT CYCL No averaging Averaging for all scans of the measuring channel from Start till Stop Averaging for all scans of the measuring channels over cycle In addition to the average value of the selected channel, the menu will also display the number of averaged values. The average value can be deleted separately or in combination with all maximum and minimum values. • Measured value output (output function, cycle factor) Instead of the current measured value, it is possible to output other measuring functions, such as maximum value, minimum value, average value, or alarm value. This function can be programmed in the “Output function” menu (see ALMEMO® Manual 6.10.4). Saving to memory, analog output, and digital output will then only process the appropriate function value. For monitoring the changed output function, the symbols listed below will pop up in the measuring channel display. Examples: 1. If measured values are being averaged with the aid of the measuring cycle the only output value of interest is the average value itself, not the last measured value. With a data logger this saves memory capacity. 2. The analog measured value from dew sensor FH A946-1 is not really significant. If limit value - maximum is set to approximately 0.5 V and the alarm value function is programmed, the only values received are 0.0% for dry and 100.0% for dew. Output function Measured value (Mxx) Control symbol Difference (Mxx-M00) Maximum value (Mxx) Minimum value (Mxx) Average value (Mxx) Alarm value (Mxx) • Limit values For every measuring channel, two limit values (maximum and minimum) can be - 60 - programmed. Exceeding one of these limit values is treated as an error, i.e. the red alarm LED will light up and the integrated beeper will sound. In the application of the control unit the measured values will appear red in case the limit value - maximum has been overshot and blue in case the limit value - minimum has been undershot. Since the maximum and minimum values are highlighted with this color coding, it is still possible at the end of the measurement to see whether limit values have been exceeded. The disturbance is only considered to have cleared when the measured value has returned to within the limit value by 10 digits (hysteresis). Normally the hysteresis is 10 digits for all channels; however the hysteresis setting can be modified in the range of 0 to 99 digits. Exceeding the limit value can also be used for starting or stopping a measurement. • Limit value actions A possible limit value action for the event of a limit value being exceeded is not only to trigger a total alarm as alarm message, but also to assign to each limit value a relay maximum or a relay minimum of a relay adapter. The relay is only deactivated if the measured value has returned to within the limit value by the hysteresis. If no limit value has been set, the measuring range limit is considered as limit value. A sensor breakage will trigger an alarm in any event. It is possible to assign several limit values to one relay. Measurement operation control: The event of a limit value being exceeded can not only be used to trigger an alarm message but also to control a measurement operation (see ALMEMO® Manual 6.6.3). To assign the commands to a limit value - maximum or limit value - minimum, the functions “Action - maximum” and “Action - minimum” must be used. The following actions can be assigned to these functions via a checkbox: alarm only, start measuring, stop measuring, set timer to zero, macro 5 ... 9 You can delete the actions by entering “alarm only” again. • Analog output (start, end) The analog output of measured values to analog output modules (see ALMEMO® Manual 5) must be scaled to a determined range. To do so, you just have to specify “Analog start” and “Analog end” for the required display range in the “Analog output” menu. This range will then be displayed on the analog range 2 V, 10 V, or 20 mA. These two parameters are also saved to the EEPROM of the sensor and thus are individually programmable for every channel, i.e. when manually switching through the channels every measuring variable can be individually scaled. The menu also enables you to switch from 0-20 mA to 4-20 mA. - 61 - • Scaling values To correctly display the electrical signal of a sensor as a measured value in physical units, a zero-point shift as well as a multiplication by a factor is nearly always necessary. For this purpose, the functions “Base value” and “Factor” are available. You will find a detailed description (with an example) of scaling in the ALMEMO® Manual, chapter 6.3.11. Actual value = (corrected value – BASE VALUE) x FACTOR The FACTOR can be programmed within the range -1.9999 to +1.9999. For factors above 2.0 or below 0.2 the decimal point shift should be specified by entering the exponent. The exponent can be used to shift the decimal point to the left (-) or to the right (+) as far as this can be presented on the display. An exponential view of measured values is not possible with standard sensors. When scaling values have been programmed and the actual value has therefore been corrected, a correcting arrow will be displayed as measured values status when displaying the measuring channel. • Correction values Sensors can be corrected for zero-point and gain with the correction values ZEROPOINT and GAIN (see ALMEMO® Manual 6.3.10). Corrected measured value = (measured value – ZERO-POINT) x GAIN When correction values have been programmed and the actual measured value has therefore been changed, a correcting arrow will be displayed as measured values status when displaying the measuring channel The option KL enables a multi-point calibration of the sensors in order to achieve maximum accuracy. Some sensors are calibrated by the means of calibration offset and calibration factor when leaving our factory. These two work like correction values – you can monitor them in this menu but you cannot change them. • Element flags To enable sensor-specific additional functions, so-called element flags are activated or can be activated for some ranges (see ALMEMO® Manual 6.10.3). • Channel compensation In the “Channel compensation” menu all compensations such as temperature - 62 - compensation, atmospheric pressure compensation, and cold junction compensation are listed for each channel with the values relevant for calculating the measured value. These values can be programmed values, internally measured values, or externally measured values. • Cross-section area To determine the volume flow in flow channels, the medium flow velocity is multiplied with the cross section area. In this menu you can enter the cross-section area in cm2. (see ALMEMO® Manual 3.5.5). 11.7.3. Sensor configuration (D6, D7) The “Sensor configuration” menu is a sensor menu individually provided by the sensor, in which the sensor can be configured via an input mask. This menu enables you to e.g. select different sections of the sensor (with different resolution and sampling rate) or to parameterize the sensor via inputs (e.g. input of the cell constant for conductivity probes). The following Figure displays an exemplary sensor menu of a D7 potential plug. Figure 21 Exemplary sensor menu 12. Maintenance and care This chapter lists the steps necessary to maintain the functionality and extend the operating life of the device. • • Cleaning the housing: If soiled, clean the housing with a damp cloth. Do not use aggressive detergents or solvents! Cleaning the plug-in modules: On a regular basis, free the plug-in module from dust that can enter in - 63 - the housing through the pinhole aperture. To do so, gently pull out he plug-in modules (for this purpose, the two front panel screws must be loosened) and clean the interior of the housing with a damp cloth. Carefully remove the dust from the electronics with some compressed air. Only work at low pressure. A pressure that is too high may cause damage on the electronics. Make sure that the device is completey voltage-free before cleaning it, i.e. unplug the mains unit! • Batteries: Please charge your batteries on a regular basis and permanently provide a sufficient charging level. Deep discharges will severely limit the operating life of the battery! - 64 - 13.
