Low Range Current Measurement Calibration for Units with Firmware
Revisions Prior to B.00.00
This only applies to Agilent Models N6761A and N6762A with
Firmware revisions prior to B.00.00. Replace steps 25 through 30 of
the previously documented procedure with the following steps.
Step 25. Remove all loads from the output and turn the output off. Wait a
minimum of 3 minutes with the output off before proceeding.
Step 26. Select the low-current measurement range. The following example
selects the 0.1 amp low-current measurement range of channel 1. The
value to program a range must be the maximum current of the range.
Front Panel: SCPI Command:
Select
System\Cal\Sequences\Imeas.
CAL:CURR:MEAS 0.1

Step 27. Steps 27 and 28 only apply to units with firmware revision A.01.04.
If your unit has firmware revision A.01.03 or below, skip these steps
and go to step 29.
Wait a minimum of 4 minutes for the internal temperature to
stabilize. Then select the first current calibration point.
Front Panel: SCPI Command:
Select Next. The information field
should indicate: Enter P1 data
CAL:LEV P1
*OPC?
Step 28. Re-connect the precision shunt resistor to the output and connect the
DVM across the shunt. Select the second current calibration point.
Front Panel: SCPI Command:
Select Next. The information field
should indicate: Enter P2 data
CAL:LEV P2
*OPC?
Step 29. This step only applies to units with firmware revision A.01.03 or
below. If your unit has firmware revision A.01.04, skip this step.
Re-connect the precision shunt resistor to the output and connect the
DVM across the shunt. Select the second current calibration point.
Front Panel: SCPI Command:
Select Next. The information field
should indicate: Enter P1 data
CAL:LEV P1
*OPC?
Step 30. Calculate the shunt current (I=V/R) and enter the data.
Front Panel: SCPI Command:
Select the Measured Data field. Enter
the data from the external DVM.
Press Select when done.
Press Next to finish calibration.
