You may do either (a) or (b) first. But be sure to do both.
1. Turn OFF the power switch of the tester.
2. Disconnect the AC power cord of the tester from the AC line receptacle.
2.3 Precautions on Testing
Wearing Insulation Gloves
When handling the tester, be sure to wear insulation gloves in order to protect yourself against high
voltages. It is forbidden to touch the live conductor by hand during high voltage test even with high
voltage insulation gloves.
Precautions for Pausing Tests
When you need to touch the test conductor or change the test connection, press the STOP switch first to
ensure that the instrument exits the test preparation state. If you are not going to resume the test soon or if
you are leaving the Test area, be sure to turn-OFF the POWER switch.
Items Charged Up to Dangerous High Voltages
When in test, the HV output, HV test leads, HV probes, DUT and output terminals and their vicinities
can be charged up to dangerous high voltages. Never touch them when in test.
WARNING： The vinyl sheaths of the alligator clips of the test leadwires which are supplied
accompanying the tester have no sufficient insulation for the high test voltages. Never touch them when in
test.
Matters to be Sure of After Turning-OFF Power
If you have to touch the DUT, test leadwires, probes, and/or output terminals and their vicinities for
re-connections or other reasons, be sure of the following two matters.
1. To confirm that the working condition is not in test mode.
2. The DANGER lamp has gone out.
Warnings for Remote Control
Be extremely careful when operating the tester in the remote control mode in which the dangerous high
test voltage is ON/OFF-controlled remotely. The operator cannot know the real working condition of the
instrument through the interface. Please pay special attention to check the reliable connection of the
remote control:
1. The “STOP” switch must be connected reliably. Press the “STOP” switch before changing the DUT.
2. When testing in a working environment with a lot of people, remote control switch has the
“INTLOCK”switch and HV lamp. Disconnect the “INTLOCK” switch before changing the DUT.
Provide means to assure that none can touch the DUT, test leadwires, probes, output terminals and their
vicinities when the test voltage is being delivered.
2.4 Warning for Residual High Voltages
WARNING: In DC withstanding voltage testing and insulation resistance testing, the test lead wire, test
