The UUT is allowed to be off for up to 5 minutes after the initial 30 minute warmup period to recon-
figure the output without observing the 30 minute warm-up period again.
Calibration Procedure
Calibration can only be accomplished remotely using SCPI commands. Once calibration has started,
the following dialog will appear on the front panel. Touching Cancel Calibration terminates the
calibration process and resets the instrument.
Voltage Programming and Measurement Calibration
Step 1. Connect the voltage input of the Keysight 3458A DMM to an output channel. Connect the
+sense terminal to the +output and the -sense terminal to the -output (see Test Setup A).
Step 2. Turn the unit on.
Step 3. Enter Calibration mode.
SCPI Command
CAL:STAT ON, [<password>]
Step 4. Select the voltage programming and measurement calibration.
SCPI Command
Specify the full-scale voltage range.
Full scale ranges vary by model.
This selects the 160 V range:
CAL:VOLT 160, (@1)
Step 5. Select the first voltage calibration point.
SCPI Command
CAL:LEV P1
*OPC?
The next step applies the full rated output voltage of the unit to the output.
Step 6. Select the second voltage calibration point. Measure the output voltage with the DMM and
enter the data.
