3. Precautions before Use and Installation
3.1 Precautions before Use
The Tester can output up to 1kV 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. Electric shock
To prevent the incident of electric shock from occurring, it is suggested to wear the
insulated rubber gloves before using the Tester for electricity related tasks.
2. 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.
