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
setups required for verification. Also refer to the
connecting the voltmeter, current shunt, and load.
SHOCK HAZARD, LETHAL VOLTAGES Many models generate voltages greater than
60 VDC, with some models rated at 950 VDC! Ensure that all instrument
connections, load wiring, and load connections are either insulated or covered using
the safety covers 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 overvoltage 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.
