Calibration Interval
Keysight Technologies recommends that complete verification should always be performed at the
calibration interval. If the power supply passes the verification tests, the unit is operating within its
calibration limits and does not need to be calibrated. This ensures that the instrument will remain
within specifications for the next calibration interval and provides the best long-term stability.
Performance data measured using this method can be used to extend future calibration intervals.
One Year Calibration Interval
The instrument should be calibrated on a regular interval determined by the accuracy requirements of
your application. A one-year interval is adequate for most applications. Accuracy specifications are
warranted only if adjustment is made at regular calibration intervals. Published accuracy
specifications are not warranted beyond the one-year calibration interval.
Three Year Calibration Interval
Voltage and current programming and measurement accuracy specifications can be extended to a
three-year period calibration interval by multiplying (or increasing) the one-year calibration accuracy
specifications shown in the verification
by a factor of three.

Voltage Calibration
Voltage Programming and Measurement
Step 1. Connect the voltage input of the Keysight 3458A DMM to the output (see
).
Step 2. Select the voltage programing and measurement calibration.
Front Panel Menu Reference
SCPI Command
Select System\Admin\Cal\Vprog.
Check that the voltmeter is connected and select Next.
Specify the full-scale voltage range. Full scale
ranges vary by model. This selects the 60 V range:
Step 3. Select the first voltage calibration point. Measure the output voltage with the DMM and enter
the data.
