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.
1. High voltage module replacement
If users replace or switch the 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.
2. Electric shock
To prevent the incident of electric shock from occurring, it is suggested to wear the
insulated rubber gloves before using the Hipot Tester for electricity related tasks.
3. 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 Figure 3-1.
4. Connecting test cable to LOW terminal
It is necessary to check if the test cable is connected all the time when the Tester is in
use. When connecting a test unit with test cable, connect the RTN/LOW test cable to the
UUT first. When the host RTN/LOW terminal is connected, it is very dangerous if the test
cable on RTN/LOW terminal is not connected correctly or falls as the entire UUT may full
of high voltage.
5. Connecting the test cable to high voltage output terminal
When the RTN/LOW test cable is connected, follow the steps below to connect the high
voltage output cable.
