Precaution before Use
3. Precaution before Use
The tester is with high voltage output up to 6KV sending to external test. It may occur injury
and death result from error operation. Please peruse notice item of this chapter and
remember to avoid accident.
1. Shock Hazard
For preventing shock be occurred. Before using the tester, put on insulation glove firstly
and then running function related to electricity.
2. Grounding

machine under the above statuses. It may cause shock hazard, therefore please make
sure to connect ground terminal to earth. As Figure 3-1 arrow denoted.
Figure 3-1
3. Connect test cable to RTN/LOW terminal
As Figure 3-2 arrow denoted, connect test cable to RTN/LOW terminal. It is necessary
to check if there is loosen or drop under operation condition at any time. If you want to
connect DUT by testing cable, please connect test cable of RTN/LOW terminal to DUT.
(RTN/LOW terminal, which has connected to the main unit) The uncompleted
connection of test cable of RTN/LOW terminal or drop is very danger, as there is full of
high voltage on DUT.
