Agilent Technologies 66311B, 66111A manual Steps 27-32 apply to Agilent 66309B/D output 2 only, 157

Verification and Calibration - B

Steps 27-32 apply to Agilent 66309B/D output 2 only

27.Connect the appropriate current monitor to output 2 as shown in figure B-1A. Connect the DMM (in voltage mode) across the current shunt. Select output 2.

28.	Press Shift Cal, scroll to CAL CURR2, and press Enter.	CAL:CURR2
29.	Press Shift Cal, scroll to CAL LEV, and press Enter to select the first	CAL:LEV P1
	calibration point.
30.	Press Shift Cal and scroll to CAL DATA. Wait for the DMM reading to	CAL:DATA 0.00
	stabilize. Then read the DMM and compute the first current value (DMM
	reading ÷ shunt resistance). Press Enter Number and enter the first current
	value in amperes.
31.	Press Shift Cal, scroll to CAL LEV, use ⊃ to scroll to P2 (the second	CAL:LEV P2
	calibration point), and press Enter.
32.	Press Shift Cal and scroll to CAL DATA. Wait for the DMM reading to	CAL:DATA 0.00
	stabilize. Then read the DMM and compute the second current value (DMM
	reading ÷ shunt resistance). Press Enter Number and enter the second current

value in amperes.

Action Display

33Disconnect all loads from the dc source but leave the sense jumpers in place. Do not connect any equipment to the output until after step #34.

34. Press Shift Cal, scroll to CAL CURR MEAS LOW, and press Enter. CAL:CURR:MEAS:LOW

35.Connect the 800 ohm calibration load resistor to output 1 as shown in figure B-1B. Connect the external DMM (in current mode) in series with the load.

36.	Press Shift Cal, scroll to CAL LEV, and press Enter to select the first	CAL:LEV P1
	calibration point.
37.	Press Shift Cal and scroll to CAL DATA. Wait for the DMM reading to	CAL:DATA 0.00
	stabilize. Press Enter Number and enter the current reading displayed on
	the DMM in amperes.

AC Current Measurement Calibration (applies to Agilent 66311B/D, 66309B/D output 1 only)

Action Display

38.Disconnect all loads from the dc source but leave the sense jumpers in place.

39. Press Shift Cal and scroll to CAL CURR MEAS AC, and press Enter. CAL:CURR:MEAS AC

40.Wait for the dc source to compute the ac current calibration constant. The display returns to Meter mode when the calculation is complete.
