Model 8000 The Model 8000 Calibrator can be operated from an AC power source of 90-132 Volts or 175-264 Volts, 47-63Hz. The Power Entry Module, located on the rear panel, provides a dual voltage selector which is integrated with the fuse holder. The line fuse is rated at 10 Amps Slow Blow, set at 115; 5 Amps Slow Blow set at 230. The present line voltage configuration is displayed in the voltage window of the fuse cover located on the rear panel adjacent to the line cord connector. To change selected voltage, first disconnect the power cord to the calibrator. Open the fuse cover using a small blade screwdriver or similar tool. Pull up the red fuse holder/voltage selector module. Remove the fuse. A conversion clip is installed on the fuse holder/voltage selector module set for single fusing. Remove the clip and place it on the opposite side. Install a fuse, one of the appropriate rating, into the opposite side of the fuse holder. Replace the fuse holder so that the desired voltage is displayed through the voltage window when the fuse door is closed.
!
WARNING !
Replace fuse only with a 250V fuse of noted rating. Always use fuses of type T (SB). Use of incorrect fuses could result in damage to the calibrator and injury to personnel!
A three-conductor power cable is provided and when this cable is connected to a standard three-wire outlet the instrument chassis is connected to earth ground. This feature prevents the instrument case from assuming voltages that are potentially hazardous to personnel. In the event that an adapter is used to connect the three-wire cable to a two-wire outlet the green (ground) adapter terminal should be connected to the earth ground.

2. Output Setting Edit Keys. The Output Setting Edit Keys are used to select which output parameter is to be modified. The keys labeled V, A, VA, φ, and Hz are used to modify Voltage, Current, Volt-Amperes, Phase Angle, and Frequency. Pressing one of these keys will cause the selected field in the Output Settings Display to be highlighted, indicating that it is ready to be edited. 3. Numeric Keypad. The Numeric Keypad is the means by which all numeric entries are made. Once a certain output parameter has been selected for modification, a new value may be keyed in using the keypad. The Keypad provides the digits 0 to 9 and also includes a decimal point and ± symbol. The ± key is used to change the polarity of an entry, if the output parameter being edited supports negative values. Valid entries for each of the output parameters are described below. Voltage: Values from between 9V and 700V may be entered. Current: Values from between 900µA and 10A may be entered. Always enter the desired value in the units indicated in the output setting display. If the indicated units are A then 100mA would be entered as 0.1A. Whenever an entry is made which is less than 1A the display will automatically change the units to mA to maintain resolution. Thus, when 0.1A is entered, the display will change to 100.000mA. To enter a setting of 5A, the value 5000mA would be entered and the display will change to 5.00000A. Volt-Amperes: The maximum and minimum values for this field depend on the present settings for both voltage and current. This field is automatically updated when either the voltage or current settings are changed. When this setting is changed the value of the current setting is updated to maintain the appropriate Voltage × Current relationship. The units of this field may be expressed as either VA, Watts or VARs. Frequency: Values from between 25 and 1000Hz may be entered. Phase Angle: Values from between +180.0 and -180.0° may be entered. The units of this field may be changed from Degrees to Radians or Power Factor. 4. Enter Key. The ENTER key is used to complete any numeric entry such as changing the setting of one of the output parameters. Pressing the ENTER key causes the new setting to take effect and exits the setting edit mode. 5. Cancel Entry Key. The Cancel Entry Key causes the removal of the editing highlight from the currently selected output parameter. The display will revert to the setting that was active when the editing process was begun. 6. Setting Control Knob. The Setting Control Knob may be used to change any specific digit of one of the output setting parameters. Rotating the knob clockwise will cause the selected digit to increment and rotating the knob counterclockwise will cause that digit to decrement, providing that the setting is valid. Changes to the output setting which are made with the setting control knob take effect at the output terminals

immediately and there is no need to press the enter key except to indicate the conclusion of the setting edit function. 7. Digit Selection Keys. The Digit Selection Keys are used to select which digit is to be modified as the setting control knob is adjusted. 8. Voltage Output Terminal Array. The Voltage Output Terminal Array consists of 4 voltage terminals, 2 output and 2 Sense. The right two terminals are the voltage high and voltage low output terminals. All voltage outputs are derived from these terminals. The left 2 terminals are the Sense High and Sense Low terminals. These terminals are used to make the sense connections in a four-wire voltage connection. The current and voltage outputs are completely isolated.
!
WARNING !
Caution should be used when making and removing connections to the voltage output terminal array. Always ensure that the calibrator is in the STANDBY state before changing connections. Failure to use appropriate care could result in dangerous electric shock!
9. Current Output Terminals The Current Output Terminals consist of Current Output High and Current Output Low terminals. The Current Output Terminals allow for both binding post and banana type connections. The current and voltage outputs are completely isolated. 10. Output Control Keys There are two Output Control Keys, STANDBY and OPERATE. When in the standby state, the green LED located above the STANDBY key is illuminated. The Voltage terminals are configured as an open circuit and the current terminals are shorted and the output amplifiers are removed from each. Once the desired settings have been established, pressing the OPERATE key will cause these settings to be present at the output terminals. At voltage settings of greater than 30V an audible warning can be sounded for one second before the output is actually activated. Whenever the calibrator is in the OPERATE state the red LED located over the OPERATE key is illuminated. To remove the output and restore the output terminals to a safe condition, simply press the STANDBY key. The STANDBY key is the only key that functions when the calibrator is in the remote state. Pressing the STANDBY key when in REMOTE and OPERATE will cause the calibrator to revert to the standby state and local control. Pressing this key when in REMOTE and STANDBY will cause the calibrator to simply revert to local control. 11. DMM Input Terminals (Optional). The DMM Input Terminals consist of 3 terminals labeled V, COM, and I. The terminal labeled V is used for AC and DC voltage or frequency inputs. Maximum voltage input is 1000V. Then terminal labeled I is for AC or DC current inputs. Maximum current input is 25mA. The terminal labeled COM is the common for both the voltage and current input terminals. Located to the left of the current input terminal is a protection fuse for the current input.

12. Menu Selection Keys. The Menu Selection Keys consist of 5 keys used to maneuver through the various configuration menus of the Model 8000. The MENU key must be pressed to activate the menu system. Pressing the MENU key when already in the menu system will exit the menu system. Once the menus have been activated, the t or s keys are used move the cursor either up or down through the menu choices. Once the desired choice is highlighted, pressing the SELECT key activates the selection. The CANCEL key closes the current menu and moves back one layer in the menu system. 13. Line Power Indicator. The Line Power Indicator is a green led indicating that power has been applied to the calibrator. The power switch itself is located on the rear panel beside the line cord receptacle. 14. System Setting Display. The System Setting Display is an LCD Graphic display which provides all information relative to the present status or configuration of the calibrator. In its normal state this display indicates the status of the calibrator. Items displayed are Status, Sense, Control and Date and Time. Status will indicate ‘OK’ in normal operation. Whenever either frequency or phase angle output settings are changed Status will indicate ‘Updating’ as the output waveform is computed and verified. In the event of either a voltage or current overload the Status will indicate either ‘V Overload’ or ‘I Overload’ respectively. The Sense item will indicate the voltage sense as either ‘Internal’ or ‘External’. The Control item will indicate the control state as either ‘Local’ or ‘Remote’. The setting of the internal real time clock is displayed in the bottom of this display. The clock settings are maintained regardless of whether the calibrator connected to line power or not. Once the MENU key is pressed the System Setting Display changes to display the main menu. The menu keys may be used at this point to navigate through the menu system.
