4、Remote interface
Use the remote probe to start up or reset of test remotely.
5、Voltage rotary knob
In the test of DUT, rotate this knob to regulate the output voltage (turn knob clockwise:
voltage rising, while counterclockwise: voltage falling)
Confirm the rotary knob is at the position of “0” before power is on.
6、Loop terminal
It is the input terminal of measured current. During the test, the terminal leads should
not be fallen off. If the test lead is fallen off, the DUT will be with high voltage and the
electric shock maybe occurred.
7、DC High voltage output terminal (H.V.)
Press „test‟ key, the terminal can generate DC high voltage. Do not touch the high
voltage port, high voltage leads, high voltage probe and DUT. After the test is finished,
make sure that all the electricity on the entire circuit has been discharged before
change another DUT.
8、AC High voltage output terminal (H.V.)
Press „test‟ key, the terminal can generate AC high voltage. Do not touch the high
voltage port, high voltage leads, high voltage probe and DUT.
9、Power supply safety detecting indicator light “O K”
Plug in, judge whether N、L、G are properly connected or not. The power switch is off, if
the N、L、G is connected rightly, the “OK” indicator will light. If the N、L、G is wrongly
connected, only “O” or “K” or neither of them is lighted. Please check the power supply.
When power on, the indicator lights out.
10、High voltage output indication
The indicator is not controlled by the main circuit. If the output voltage is more than 50V,
the indicator will light up. If it is lighted on the reset status, the H.V. terminal maybe
existed high voltage, please do not touch any part of the circuit. When the tester outputs
high voltage, the indicator lights up all the time, which indicates it is dangerous during
high voltage outputting.
11、Fail indicator
When the test is failed, the indicator will light.
12、Test indicator
When the start key is pressed, the indicator will light.
13、Voltage display 14、Current display
15、Time display
Time is range from 0.0s to 999s. When the test time is less than 100s, the resolution is
