1
Closing the power switch of instrument;
2
Unplug the power cable from the power socket.
3. Preventive measures in the testing process
1) Prevent electric shock proof with insulated gloves
In order to prevent the electric shock accident,please bring the rubber gloves with insulation
and then engage in electrical related work before using this tester.
2) Connecting with test line and current measurement port
The test line is connected to the current measurement port,the test line must be checked
whether is connected loose or fall off any time when the tester is in use, when connect the test
objects with test line,please connect the object with the test line of current measuring port.If the test
line of the current measurement port was incomplete or fall off,that is very dangerous.Because the
whole test object will likely be filled with high voltage.
3) Connecting the test line to the high voltage output port
When the test line is connected to the current measurement port,then connect the high voltage
output line as the following program.
1
Press the "STOP" key first.
2
Confirm that whether the test light is light.
3
Insert the high voltage output line into the high voltage output port
4) Replace the measured object
When a test object has been tested and replace another object,please confirm:
1
The tester is in a "reset" state.
2
The high voltage indicator doesn
’
t twinkle.
3
The display window of voltage shows that the number isn't beating any more.
Warning: don
’
t touch the high pressure probe when replace the test object!
5) Tester is in test condition
When the tester is in the test condition,the test line,the test object,the test probe and the output
port are all equipped with high pressure,please do not touch.
Note:don't touch the alligator clip of the test line with your hand,because when the host was
testing,the test line has a high voltage, the insulation on the alligator clip is not high,it will
cause an electric shock if you touch it.
6) Stop testing
