Calibrating and Entering rms Current Measurement Values

Action

Display

40.Connect the DVM (ac rms mode), current shunt, and load resistor as shown in figure B-1 with S1 closed.

41.	Press Shift Calibration, scroll to the CAL CURR MEAS command, and	CAL:CURR:MEAS
	press Enter.
42.	Press Shift Calibration, scroll to the CAL LEV P1 command, and press	CAL:LEV P1
	Enter.
43.	Press Shift Calibration, scroll to the CAL DATA 0.00 command.	CAL:DATA 0.00
	Calculate the rms current value (DVM ac rms voltage/shunt resistance), and
	use the Entry keypad to enter the rms current.
44.	Press Shift Calibration, scroll to CAL LEV P1 command, use ° to scroll	CAL:LEV P2
	to the P2 parameter, and press Enter.
45.	Press Shift Calibration, scroll to the CAL DATA 0.00 command.	CAL:DATA 0.00
	Calculate the rms current value (DVM ac rms voltage/shunt resistance), and
	use the Entry keypad to enter the rms current.

The ac source is now holding the new rms current measurement calibration constants in RAM.

Calibrating the Output Impedance

Action

Display

46.Connect only the output impedance resistor across the output of the ac source. Do not connect any other equipment.

47.	Press Shift Calibration, scroll to the CAL IMP command, and press	CAL:IMP
	Enter.
48.	Wait for the ac source to compute the output impedance calibration
	constant. The display returns to Meter mode when the calculation is
	complete.

The ac source is now holding the new output impedance calibration constants in RAM.

Saving the Calibration Constants

CAUTION: Storing calibration constants overwrites the existing ones in non-volatile memory. If you are not sure you want to permanently store the new constants, omit this step. The ac source calibration will then remain unchanged.

	Action	Display
49.	Press Shift Calibration, scroll to CAL SAVE, and press Enter.	CAL:SAVE
50.	Press Shift Calibration, select CAL OFF, and press Enter to exit	CAL OFF
	Calibration mode. RST and RCL will also set the calibration state to
	OFF.
