Precaution before Use

The Hipot Tester can output up to 8KV high voltage for external test. Accidents
may occur or even cause death if using this Tester incorrectly or in the wrong way.
Thus for safety sake, be sure to read the precautions in this chapter to avoid any
accidents from happening.
■
High voltage module replacement
If users replace or switch the 10 sets of high voltage modules on the rear
panel, to ensure the Tester output is still within the specification, users need
to recalibrate the Tester and ensure the specification.

wear the insulated rubber gloves before using the Hipot Tester for electricity
related tasks.

Grounding
A safety ground terminal is located at the rear of the Tester chassis; please
use a proper tool to ensure it is grounded accurately. If not it would be very
dangerous when the power circuit or the connection cable of any device
shorts with ground terminal as the chassis may contain high voltage.
Anyone who touches the device in this case may cause electric shock.
Therefore, it is necessary to connect the safety ground terminal to earth
properly as the arrow shows in section 3.2.
