potentiometer clockwise, the current pre-set value will be increased. Counterclockwise
adjustment will reduce the pre-set leak current. If the preset current is up to the desired
value, pop-up the test / preset button.
3.Adjust the output voltage
When the voltage regulator knob is at 0 position, even if user starts the tester from PLC,
there is no high voltage output. Start the tester by PLC interface and adjust the output
voltage knob clockwise slowly until the output voltage reaches to the required voltage.
VIII.Applying Illustration
1.Preparation of test
（

）
Avoid electric shock
Please wear insulated gloves and stand on the insulation pad when operate the hipot
tester. Note: the withstanding voltage of insulating gloves and insulated pad should be
twice than the maximum output voltage of the tester.

Set the alarm value of leak current and test time
Please refer to the seventh chapter.

Connect the DUT(Device Under Test) to the tester
Please confirm the following before connection:
1, The tester is shut down or on the reset status;
2, The high voltage indicator is not light;
3, The voltage window show 0;
Connect the current measurement loop terminal firstly then connect DUT to the high
voltage terminal.
8.2 Test mode

Manual test
If the test time is set to 0, the tester will not judge the test time during testing. The tester is
in a continuous test condition in the test.
After the "TEST" signal on PLC is enable, the test light will be lit; adjust the output voltage
