preset current increases; counterclockwise regulating preset current decreases; the alarm current
value preset to the required test value, pop test / preset button.
4. Adjustment of output voltage
When the voltage regulator knob is in the 0 place,even if start the tester,it has no high voltage
output;after starting the tester,adjust the output voltage adjusting knob clockwise,the output voltage
increased,and reach the voltage required for testing.

Test Function
1. Preparation before testing
1) Anti electric shock: first put on insulating gloves, pad pad at the foot, and then engage in high
voltage related operations. Attention: insulation gloves, insulation pad withstand voltage is at
least two times the maximum output voltage of the operating test instrument.
2) Set alarm current value and test time: refer to section seventh for setting method.
3) Connection test and test body: before connecting test instruments and subjects, please confirm:
1
The test instrument is in shutdown or reset state;
2
The high voltage indicator is not bright;
3
The voltage indication window indicates the voltage is 0 or 0.01; first, the current
measuring end of the test instrument is connected with the tested body, and then the high voltage
line and the tested body are connected.
2. Testing method
1) Manual test
The test time is set to 0, the test instrument does not determine the test time in the test, and the
test instrument is in the continuous test state when testing. Press the "START" key, the test
instrument starts to test, the test lamp is bright, adjust the output voltage adjustment knob to achieve
the required test voltage value. After the test, press the "STOP" button to stop the test. In the test
process, if the test current is greater than the preset value, the test instrument alarm. At this point,
press the "STOP" button to clear the alarm. Change the tested body and continue testing.
2) Automatic testing
Set the test time is not 0; press the "START" button, the test instrument to start testing, test
lights, timer countdown, adjust the output voltage adjustment knob to achieve the required test
voltage value. In the test process, if the test current is greater than the preset value, the test
