Calibrating And Entering Dc Voltage Gain Values; Calibrating And Entering Ac Rms Voltage Gain Values - Agilent Technologies 6811B User Manual

11. Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry
keypad to enter the dc voltage value displayed on the DVM.
Press Shift Calibration, scroll to the CAL LEV P1 command, use ° to
12.
scroll to the P4 parameter, and press Enter.
13. Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry
keypad to enter the dc voltage value displayed on the DVM.
The ac source is now holding the new voltage offset calibration constants in RAM.

Calibrating and Entering DC Voltage Gain Values

Connect the negative terminal of the DVM to the COM output terminal. Note that some calibration
points are negative; be sure to enter the CAL:DATA as negative values when required.
Action
14. Connect the DVM (dc volts mode) directly to the ac source. Do not connect
the ratio transformer or load resistor shown in Figure B-1.
15. Press Shift Calibration, scroll to the CAL VOLT DC command, and
press Enter.
16. Press Shift Calibration, scroll to the CAL LEV P1 command, and press
Enter to select the first calibration point.
17. Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry
keypad to enter the dc voltage value displayed on the DVM.
Press Shift Calibration, scroll to the CAL LEV P1 command, use ° to
18.
scroll to the P2 parameter, and press Enter. This selects the second
calibration point.
Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry
19.
keypad to enter the dc voltage value displayed on the DVM.
Press Shift Calibration, scroll to the CAL LEV P1 command, use ° to
20.
scroll to the P3 parameter, and press Enter.
Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry
21.
keypad to enter the dc voltage value displayed on the DVM.
The ac source is now holding the new dc voltage gain calibration constants in RAM.

Calibrating and Entering AC rms Voltage Gain Values

Action
22. Connect the DVM (ac volts mode) to the ac source using the ratio
transformer shown in Figure B-1.
23. Press Shift Calibration, scroll to the CAL VOLT AC command, and
press Enter.
24. Press Shift Calibration, scroll to the CAL LEV P1 command, and press
Enter to select the first calibration point.
25. Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry
keypad to enter the product of the transformer ratio times the ac voltage
value displayed on the DVM.
