Chapter 1 Safety Specification

This tester outputs voltage as high as 5kVac/6kVdc for external testing;
accidents will happen if this tester is used incorrectly or improperly.
Therefore, in consideration of your own safety, please read the precautions
described in this chapter carefully and memorize them in order to prevent
accidents from occurring.

1.1 Electrification and Electric Shock

In order to prevent electric shocks, the wearing of insulating plastic gloves
is recommended before using this tester to perform testing related tasks.

1.2 Grounding

The back panel of the instrument is fitted with a safe ground terminal. Be
sure to connect this ground terminal to the ground to prevent the operator
from touching the housing as to cause the electrocution.

1.3 Power

Power that can be used with this machine is AC 100Vac~240Vac with a
frequency range from 47Hz~63Hz; please confirm whether the input power
voltage and frequency are within range before inserting the power.
1.4 Connect the testing cable to the high
voltage output terminal
While the tester is powered off, insert the high voltage testing cables to the
high voltage output terminals on the tester respectively, and confirm that the
exteriors of the testing cables are not ruptured or shed.

1.5 Warm up

The tester can operate normally once the power is turned on; however, in
order to achieve the accuracy within specification, please turn on the
