Agilent Technologies 6811B, 6813B, 6812B manual Calibrating and Entering DC Voltage Gain Values

Verification and Calibration - B

11.	Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry	CAL:DATA 0.00
	keypad to enter the dc voltage value displayed on the DVM.
12.	Press Shift Calibration, scroll to the CAL LEV P1 command, use ° to	CAL:LEV P4
	scroll to the P4 parameter, and press Enter.
13.	Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry	CAL:DATA 0.00
	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.

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	CAL:VOLT:DC
	press Enter.
16.	Press Shift Calibration, scroll to the CAL LEV P1 command, and press	CAL:LEV P1
	Enter to select the first calibration point.
17.	Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry	CAL:DATA 0.00
	keypad to enter the dc voltage value displayed on the DVM.
18.	Press Shift Calibration, scroll to the CAL LEV P1 command, use ° to	CAL:LEV P2
	scroll to the P2 parameter, and press Enter. This selects the second
	calibration point.
19.	Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry	CAL:DATA 0.00
	keypad to enter the dc voltage value displayed on the DVM.
20.	Press Shift Calibration, scroll to the CAL LEV P1 command, use ° to	CAL:LEV P3
	scroll to the P3 parameter, and press Enter.
21.	Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry	CAL:DATA 0.00
	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 Display

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	CAL:VOLT:AC
	press Enter.
24.	Press Shift Calibration, scroll to the CAL LEV P1 command, and press	CAL:LEV P1
	Enter to select the first calibration point.
25.	Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry	CAL:DATA 0.00
	keypad to enter the product of the transformer ratio times the ac voltage
	value displayed on the DVM.
