If the instrument fails any of the tests or if abnormal test results are obtained, try calibrating the unit. If
calibration is unsuccessful, return the unit to a Keysight Technologies Service Center.
Refer to the Recommended Test Equipment and Setups section for a list of the equipment and test
setups required for verification. Also refer to the Measurement Setups section for information about
connecting the voltmeter, current shunt, and load.
SHOCK HAZARD, LETHAL VOLTAGES - Some models generate output voltages up
to 2,000 VDC! Ensure that all instrument connections, load wiring, load and sense
connections are insulated using high-voltage wire. Always attach the safety cover
provided, so that no accidental contact with lethal voltages can occur.
Always turn off the output when connecting or disconnecting any equipment on the
sense or output terminals of the unit.
Equipment Damage It is recommended to set the over-voltage protection function
of the instrument slightly higher than its operating point during the verification
procedure. This will prevent damage to any external equipment (electronic load,
differential amplifier) that may occur if the output voltage is accidentally
programmed higher than the prescribed voltage setting.
Turn the unit off or send a Reset command after completing the verification
procedure to return all instrument settings to their default values.
