fourYDJ-3ll-S power frequency withstand voltage testerUsage

1When using the testing instrument, the casing should be safely and reliably grounded.

2The operator must step on a suitable insulation pad.

3Connect the power cord properly.

4Connect the test sample.

5Pre set the test time（3）And alarm limit current（4）

6Turn on the power switch(9)Press“ONAt the position,The indicator light inside the switch is on）

7Press the start button to start the test, then turn the voltage regulator knob clockwise to raise the voltage to the test voltage. If there is no alarm sound from the test sample, it indicates that the test sample is qualified. If broken down, indicator light（5）If it is lit and accompanied by an alarm sound, the test sample will not be tested

5、 Precautions for YDJ-3ll-S power frequency withstand voltage tester

1This device is a high-voltage testing instrument, and when the instrument is powered on, it should be ensured that the instrument casing is well grounded.

2Do not place it in high temperature, humidity, excessive dust, or corrosive areas.

3When checking the inside of the instrument, the power should be turned off.

4Before changing the test sample or switching the wiring, the stop button must be pressed or the power must be turned off.

5Avoid strong vibrations and mechanical impacts when moving and using.

6、 When the high-voltage output line is worn out, it should be replaced in a timely manner.
