20.Connect the appropriate current shunt and load resistor as shown in figure B- 1. Connect the DVM (ac rms mode) across the current shunt.

If you are calibrating a 3-phase source , make sure that the default phase 1 (φ1) annunciator is lit. Press Phase Select to select a different phase.

21.	Press Shift Calibration, scroll to CAL CURR AC, and press Enter.	CAL:CURR:AC
22.	Press Shift Calibration, scroll to CAL LEV P1, and press Enter.	CAL:LEV P1
23.	Press Shift Calibration and scroll to CAL DATA. Wait for the DVM	CAL:DATA 0.00
	reading to stabilize. Read the DVM and calculate the first current value
	(DVM ac rms voltage divided by the shunt resistance). Use the Entry keypad
	to enter the rms current value.
24.	Press Shift Calibration, scroll to CAL LEV P1, use ° to scroll to the P2	CAL:LEV P2
	parameter, and press Enter.
25.	Press Shift Calibration and scroll to CAL DATA. Wait for the DVM	CAL:DATA 0.00
	reading to stabilize. Read the DVM and calculate the second current value
	(DVM ac rms voltage divided by the shunt resistance). Use the Entry keypad
	to enter the rms current value.

26.If you are calibrating a 3-phase source , press Phase Select to select the next phase and repeat steps 20 through 25 for phases 2 and 3.

The phase annunciators on the front panel indicate which phase is active.

27.	Press Shift Calibration, scroll to CAL CURR MEAS, and press Enter.	CAL:CURR:MEAS
28.	Press Shift Calibration, scroll to CAL LEV P1, and press Enter.	CAL:LEV P1
29.	Press Shift Calibration and scroll to CAL DATA. Wait for the DVM	CAL:DATA 0.00
	reading to stabilize. Read the DVM and calculate the first current value
	(DVM ac rms voltage divided by the shunt resistance). Use the Entry keypad
	to enter the rms current value.
30.	Press Shift Calibration, scroll to CAL LEV P1 command, use ° to scroll	CAL:LEV P2
	to the P2 parameter, and press Enter.
31.	Press Shift Calibration and scroll to the CAL DATA. Wait for the DVM	CAL:DATA 0.00
	reading to stabilize. Read the DVM and calculate the second current value
	(DVM ac rms voltage divided by the shunt resistance). Use the Entry keypad
	to enter the rms current value.

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