Calibration Procedures

Keysight U1281A/U1282A Service Guide

Vsense (non-contact voltage) calibration

Turn rotary switch to

position with the

shown on the display.

Connect a dual open type banana plug into the output voltage terminals of the

calibrator.

Ensure the

EARTH

button of calibrator is on.

Hold the multimeter so that the top of the multimeter is vertically and

horizontally centered and in contact with the banana plug’s Hi terminal.

Set the source output to 10 V/55 Hz.

Press

to start the calibration. If the calibration is successful,

will

be displayed.

Set the source output to 30 V/55 Hz.

Press

to start the calibration process.

Set the calibrator to standby mode when the calibration is done.

See

Figure 1-8

for the multimeter display.

NOTE

– Ensure the multimeter is REMOVED from the holster prior to performing this

calibration.

– Keep the multimeter away from fluorescent lights, dimmable lights, motors,

and other electrical noise sources when running the tests. These electrical

noise sources can invalidate the calibration.

– It may be necessary in

step 4

and

step 8

below to slightly adjust the position

of the multimeter for maximum signal strength.
