Panel Instructions:
1. Power switch;
2. Start button: when pressed, the test lamp will be on, and the instrument will output high voltage;
3. Reset button: when pressed, the test lamp will be off, and there will be no high-voltage output;
4. Voltage regulation button: adjust the output voltage, which is small in inverse time and large in
reverse;
5. Test light: the light is on, indicating that the high voltage has been started, and the high voltage is
disconnected when the light is off;
6. Over-leakage light: the light is on, indicating the breakdown of the measured object, and over-leakage
is unqualified;
7. High voltage output terminal: -DC high voltage output terminal;
8. High voltage output terminal: AC high voltage output terminal;
9. Voltmeter: output voltage indicator;
10, time timer: 1s~99s timing adjustment, you can set the required test time value;
11. Selection switch of the range of leakage current: switch the range of leakage current indicating
ammeter. The switch pops out as the range of 0-2ma, and the switch presses down as the range of
2-10ma.
12. Preset/test switch of leakage current: press the switch to set the alarm value of leakage current, and
the switch will pop out. When normal, it will be the test state, and the value of leakage current can be
detected in real time through "leakage current indicating ammeter".
