When switching the range calibrator to STANDBY, allow enough time for the
NOTE
range calibrator to settle to its zero value before attempting to zero the Keysight
N1911A/1912A P-Series power meter. This settling would appear on the
Keysight N1911A/1912A P-Series power meter display as downward drift. When
the drift has reached minimum, (typically less than 60 seconds), the range
calibrator is settled.
3 Turn on the voltmeter and allow it to warm up for 4 hours.
4 Turn on the DC source and allow it to warm up. Set the output voltage to 0 V.
5 Turn on the DUT and allow it to warm up for 30 minutes.
6 Ensure the range calibrator is not plugged-in or powered on.
7 Connect the range calibrator to the DUT using the power meter interconnect
8 Connect the DC source to the range calibrator external voltage input and the
