EC Declaration of Conformity
10
Conformity with FDA 21 CFR Part 11 In their directive “Title 21 Code of Federal Regulations, 21 CFR Part 11, Electronic Records; Electronic Signatures“ the American health agency FDA (Food and Drug Administration) regulates the production and processing of electronic documents for pharmaceutical development and production. This results in requirements for transmitters used for corresponding applications. The following features ensure that the transmitters of the H200X series meet the demands of FDA 21 CFR Part 11: Electronic Signature Access to the device functions is regulated and limited by individually adjustable codes – “Passcodes” (for Passcode Editor see Page 54, overview of factory settings on back of manual). This prevents unauthorized modification of device settings or manipulation of the measurement results. Appropriate use of these passcodes makes them suitable as electronic signature. Audit Trail Every (manual) change of device settings can be automatically documented. Each change is tagged with a “Configuration Change Flag”, which can be interrogated and documented using HART communication. Altered device settings or parameters can also be retrieved and documented using HART communication.

Safety Functions Sensocheck, Sensoface Sensor Monitoring Sensocheck continuously monitors the sensor and its wiring. Sensocheck can be switched off (Configuration). Sensoface provides information on the sensor condition. The asymmetry potential (zero), slope and response time during calibration are evaluated. The three Sensoface indicators provide the user with information on wear and required maintenance of the sensor. GainCheck Device Self-Test A display test is carried out, the software version is displayed, and the memory and measured value transfer are checked.
Start GainCheck device self-test: + Automatic Device Self-Test The automatic device self-test checks the memory and measured-value transfer. It runs automatically in the background at fixed intervals.
31
Safety Functions Hold Mode Display: The Hold mode is a safety state during configuration and calibration. Loop current is frozen (Last) or set to a fixed value (Fix). If the calibration or configuration mode is exited, the device remains in the Hold mode for safety reasons. This prevents undesirable reactions of the connected peripherals due to incorrect configuration or calibration. The measured value and “HOLD” are displayed alternately. The transmitter only returns to measuring mode after enter is pressed and 20 seconds have passed.
32
Outputs Loop current The loop current is controlled by the process variable selected in the configuration. The current start and end can be set to represent any desired value. To check connected peripherals (e.g. limit switches, controllers), the loop current can be manually specified (see page 70).
HART communication H200X pH can be remote-controlled via HART communication. It can be configured using a handheld terminal or from the control room. Measured values, messages and device identification can be downloaded at any time. This allows easy integration also in fully automatic process cycles. If you require “Transmitter-Specific Command Specifications”, please contact Hamilton.
Alarm The alarm delay is configurable. Error messages can also be signaled by a 22 mA loop current (see Configuration, page 53). The alarm LED on the front panel can be configured as follows: HOLD off: Alarm: LED blinks HOLD on: Alarm: LED on. HOLD: LED blinks
33
Configuration In the Configuration mode you set the device parameters. Activation
Activate by pressing conf Enter passcode “1200“ Use and to edit a parameter. Press enter to confirm/continue. (Exit by pressing conf enter.)
Hold
During configuration the device remains in the Hold mode for reasons of safety. The loop current is frozen (at its last value or at a preset fixed value, depending on the configuration), Sensoface is off, “Configuration” mode indicator is on. HOLD icon
Input errors
The configuration parameters are checked during the input. In the case of an incorrect input, ”Err” is displayed for approx. 3 sec. The incorrect parameters cannot be stored. Input must be repeated.
Exit
Exit by pressing conf. The measured value and Hold are displayed alternately, “enter” blinks. Press enter key to exit the Hold mode. The display shows the measured value. The output current remains frozen for another 20 sec (HOLD icon on, “hourglass” blinks).
34
Menu Structure of Configuration The configuration steps are assigned to different menu groups: • Current output (code: o1.) • Temperature compensation (code: tc.) • Calibration mode (code: CA.) • Alarm settings (code: AL.) You can jump between the individual menu groups by using the arrow keys. Each menu group contains menu items for setting the parameters.
Example: “o1.” is displayed with all menu items of the “Current output” menu group.
Pressing enter opens a menu item. Use the arrow keys to edit a value. Press enter to confirm/save the settings. Return to measurement: Press conf. Select menu group

pH calibration Calibration is used to adapt the device to the individual sensor characteristics, namely asymmetry potential and slope. Calibration can be performed with Calimatic automatic buffer recognition, with manual buffer input, by entering premeasured electrode data, or by sampling the product. Caution • All calibration procedures must be performed by trained personnel. Incorrectly set parameters may go unnoticed, but change the measuring properties. • The response time of the sensor and temperature probe is considerably reduced when the sensor is first moved about in the buffer solution and then held still. • The device can only operate properly when the buffer solutions used correspond to the configured set. Other buffer solutions, even those with the same nominal values, may demonstrate a different temperature response. This leads to measurement errors. When using sensors with a zero point other than pH 7, the nominal zero point must be adjusted each time a new sensor is connected. This is important if you want to obtain reliable Sensoface messages. The Sensoface messages issued during all further calibrations are based on this basic calibration.
57
Automatic calibration with Calimatic (BUF -xx-) Automatic or manual temperature detection The device can only operate properly when the buffer solutions used correspond to the configured set. Other buffer solutions, even those with the same nominal values, may demonstrate a different temperature response. This leads to measurement errors.

Product Calibration Calibration by sampling During product calibration the sensor remains in the process. The measurement process is only interrupted briefly. Procedure: During sampling the currently measured value is stored in the device. The device immediately returns to measuring mode. The calibration mode indicator blinks and reminds you that calibration has not been terminated. The sample is measured in the lab or directly on the site using a portable meter. To ensure an exact calibration, the sample temperature must correspond to the measured process temperature. The measured sample value is then entered in the device. From the difference between the stored measured value and entered sample value, the device calculates the new asymmetry potential (one-point calibration). If the sample is invalid, you can take over the value stored during sampling. In that case, the old calibration values are stored. Afterwards, you can start a new product calibration.

After end of calibration, the outputs remain in Hold mode for approx. 20 sec.

ORP Calibration ORP calibration mode is automatically preset when ORP measurement is configured. The potential of a redox sensor is calibrated using a redox (ORP) buffer solution. In the course of that, the difference between the measured potential and the potential of the calibration solution is determined according to the following equation. During measurement the Transmittter adds this difference to the measured potential.
mVORP = mVmeas + ΔmV
mVORP = displayed ORP mVmeas = direct sensor potential ΔmV = delta value, determined during calibration
The sensor potential can also be related to another reference system – e.g. the standard hydrogen electrode. In that case the temperature-corrected potential (see table) of the reference electrode used must be entered during calibration. During measurement, this value is then added to the ORP measured. Please make sure that measurement and calibration temperature are the same since the temperature behavior of the reference electrode is not automatically taken into account.

Icon blinks:
Problem Possible causes Asymmetry potential out of range (±60 mV) • Sensor worn out • Buffer solutions unusable or contaminated • Buffer does not belong to configured buffer set • Temperature probe not immersed in buffer solution (for automatic temperature compensation) • Wrong buffer temperature set (for manual temperature specification) • Nominal sensor zero point ≠ pH 7
Sensor slope out of range (80...103 %) • Sensor worn out • Buffer solutions unusable or contaminated • Buffer does not belong to configured buffer set • Temperature probe not immersed in buffer solution (for automatic temperature compensation) • Wrong buffer temperature set (for manual temperature specification) • Sensor used has different nominal slope
Problems during recognition of the buffer solution • Same or similar buffer solution was used for both calibration steps • Buffer solution used does not belong to buffer set currently configured in the device
74
Icon blinks:
Problem Possible causes Problems during recognition of the buffer solution (continued) • During manual calibration the buffer solutions were not used in the specified order • Buffer solutions unusable or contaminated • Wrong buffer temperature set (for manual temperature specification) • Sensor defective • Sensor not connected • Sensor cable defective
Calibration was canceled after approx. 2 minutes because the sensor drift was too large. • Sensor defective • Sensor dirty • No electrolyte in the sensor • Sensor cable insufficiently shielded or defective • Strong electric fields influence the measurement • Major temperature fluctuation of the buffer solution • No buffer solution or extremely diluted
75
Sensoface (Sensocheck must have been activated during configuration.)
The little smiley in the display (Sensoface) alerts to sensor problems (defective sensor, defective cable, maintenance required). The permitted calibration ranges and the conditions for a friendly, neutral or sad Sensoface are summarized in the following table. Additional icons refer to the error cause.
Sensocheck Continuously monitors the sensor and leads for short circuits or open circuits. Critical values make the Sensoface “sad” and the corresponding icon blinks:
The Sensocheck message is also output as error message Err 33. The red LED is lit, the output current is set to 22 mA (when configured correspondingly). Sensocheck can be switched off during configuration (then Sensoface is also disabled). Exception: After a calibration, a smiley is always displayed for confirmation.
Note The worsening of a Sensoface criterion leads to the devaluation of the Sensoface indicator (Smiley becomes “sadder”). An improvement of the Sensoface indicator can only take place after calibration or removal of the sensor defect.

Glossary Asymmetry potential
The voltage which a pH sensor provides at a pH of 7. The asymmetry potential is different for each sensor and changes with age and wear.
Buffer set
Contains selected buffer solutions which can be used for automatic calibration with the Calimatic. The buffer set must be selected prior to the first calibration.
Buffer solution
Solution with an exactly defined pH value for calibrating a pH meter.
Calibration
Adjustment of the pH meter to the current sensor characteristics. The asymmetry potential and slope are adjusted. Either a one- or two-point calibration can be carried out. With one-point calibration only the asymmetry potential (zero point) is adjusted.
Calimatic
Automatic buffer recognition. Before the first calibration, the buffer set used must be activated once. The patented Calimatic then automatically recognizes the buffer solutions used during calibration.
Combination sensor
Combination of glass and reference electrode in one body.
GainCheck
Device self-test which runs automatically in the background at fixed intervals. The memory and measured-value transmission are checked. You can also start the GainCheck manually. Then a display test is also conducted and the software version displayed.
94
One-point calibration
Calibration with which only the asymmetry potential (zero point) is taken into account. The previous slope value is retained. Only one buffer solution is required for a one-point calibration.
Passcode
Preset four-digit number to select certain functions.
pH sensor
A pH sensor consists of a glass and a reference electrode. If they are combined in one body, they are referred to as combination sensor.
Response time
Time from the start of a calibration step to the stabilization of the sensor potential.
Sensocheck
Sensocheck continuously monitors the glass and reference electrodes. The resulting information is indicated by the Sensoface smileys. Sensocheck can be switched off.
Sensoface
Provides information on the sensor condition. The zero point, slope, and response time are evaluated. In addition, the Sensocheck information is indicated.
Sensor slope
Is indicated in % of the theoretical slope (59.2 mV/ pH at 25 °C). The sensor slope is different for each sensor and changes with age and wear.
Sensor zero point
See asymmetry potential
95
Glossary Two-point calibration
Calibration with which the sensor asymmetry potential (zero point) and slope are determined. Two buffer solutions are required for two-point calibration.
Zero point
See asymmetry potential
