Current Programming and Measurement Calibration
Step 1. Disconnect all equipment form the output terminals.
Step 2. Select the current programing and measurement calibration.

Select
System\Admin\Cal\Curr\Iprog
.
Check that nothing is connected to the output and select
Next.
Specify the full-scale current range. Full scale
ranges vary by model. This selects the 30 A range:
Step 3. Wait 5 minutes for the temperature to settle. Then select the first current calibration point.

Wait 5 minutes, then select Next again.
Step 4. Connect a precision shunt resistor to the output. The shunt resistor should be able to measure
at least 70% of the output’s full-scale current (see
). Connect the Keysight 3458A DMM
across the shunt resistor.

Step 5. Select the second current calibration point. Wait 5 minutes for the temperature to settle.
Calculate the shunt current (I=V/R) and enter the data.

Display shows: “Enter P2 measured data”. Enter the data from
the external DMM. This should be about 70% of the full-scale
current rating. Press Enter when done. Press Back to finish.
