③
Note: Don‟t touch the tested device or the devices, which are connected with it when
testing.
④
Once any problems to the tester turned up, please cut off the high voltage output and
input power.
⑤
After testing, please discharge first, and then remove the P-wire.
II.what will you notice before testing
The output of the withstanding voltage tester can output 20kV, the highest voltage. Any
false operation will result in the misadventure even death. So please read this chapter
carefully with the view of safety.
1.An electric shock
In order to avoiding the electric shock, please wear the rubber-insulated gloves before
using the tester.
2.The tester is in the testing state
When the tester is running in the testing state, the P-wire, the tested device, the test probe
and the output port all carry the high voltage. Please don‟t touch!
3.Changing the tested device
After finishing testing, when you change another tested device, please check to be sure:
①
The tester is in the reset state.
②
The test light is not flicking.
③
The figure of the voltage in the liquid-crystal display is not changing.
Especially notice: Don’t touch the high voltage probe when changing the tested device.
4.Switch on or off the power switch
Once the power is cut off, please wait for a minute if you want to start it once more.
Caution: It is very dangerous in the high voltage output state to change the power state,
“on” or “off”, continuously. It also do harm to the tester.
Don’t join the output port of the high voltage with any things when switching on or off the
power for it maybe cause the abnormal high voltage output which is very hazard.
5.Emergency treatment
In order to avoiding the more loss, please do according to the following way under any
emergent conditions such as an electric shock, the burning of the tested device or the
host:
①
First cut off the power.
②
Then unplug the plug of the power.
