Test Considerations
For optimum performance, all calibration procedures should comply with the following:
l
Ambient temperature is stable, within 23 °C ±2°C.
l
Ambient relative humidity is less than 80%.
l
30 minute warm-up period before verification or adjustment.
l
Cables as short as possible, twisted or shielded to reduce noise.

Voltage Programming and Measurement Calibration
Step 1. Connect the voltage input of the Keysight 3458A DMM to the output (see
).
Step 2. Select the voltage programing and measurement calibration.

.
Check that the voltmeter is connected and select
Next.
Specify the full-scale voltage range. Full scale ranges vary
by model. This selects the 1000 V range:
Step 3. Select the first voltage calibration point. Measure the output voltage with the DMM and enter
the data.

The next step applies 70% of the rated voltage of the unit under test to the output.
Step 4. Select the second voltage calibration point. Wait 5 minutes for the temperature to settle.
Measure the output voltage with the DMM and enter the data.
