The generator can endure direct discharge by devices of large capacitance. It is of small size and of light weight, convenient for field use.
2. Full range of linear smoothly adjusted voltage, with voltage regulation accuracy smaller than 0.1%; voltage measurement accuracy is 0.5%, resolution 0.1kv; Current measurement accuracy is 0.5%, the minimum resolution: control box 1µA, shock resistance current 0.1µA.
3. The generator uses AC 220 V power supply (AC220V±10%, 50 hz±1%), the ripple factor is less than 0.5%, and can be used for all-weather at the site .
4. High voltage multiplier uses Dupont materials for full solid encapsulation, overcoming the inconvenience brought by the air and oil filled equipment. Broad base and outer cylinder of light quality makes it stand steadily and more convenient for maintenance.
5. 75% MOA voltage switch button, simple and convenient testing arrester.
6. Over-voltage setting function displays the over-voltage value during regulation process; perfect protection against discharge of over-voltage, over-current and short circuit. This is the best companion for cable experiments.
7. Perfect break line and non-zero potential start protection function protects the operator and samples at any time. This product has overall design of shock-proof control box, concise, clear panel design and voice prompt for operation.

Panel of DC Hipot Tester as below:

1. Voltmeter: displays the output voltage. Display unit: KV.  Maximum display: 999.9KV
2. Ammeter: displays the output current (including sample's leakage current and leakage current in the air, etc. )
Maximum display 9999 uA, except special made.
3. Power socket: single phase AC220V±10% 50HZ power input.
4. MOA 75% signal light:  signal light is on when voltage change is more than 75% V1mA. The voltmeter displays the highest output voltage value, not the actual output voltage. Once the voltage regulation knob is back to zero, reset, the light is off.
5. Aviation socket: please align positioning pin, and press the plug in, then tighten clockwise to connect socket. Counterclockwise to back out. Note: please hold tight the plug metal rings, do not grasp or pull the line. Improper disassembling or connection will shorten the life span of the connecting line.
6. Ground terminal: connect the ground wire to the grounding screw at the bottom of the generator.
7. MOA 75% button: during test of zinc oxide lightning arrester, V_1mA is high voltage value when leakage current is1mA. Press MOA 75% button, voltage drop automatically to 75% V_1mA, conversion accuracy is better than 0.5%.
8. Voltage rough adjustment knob: Clockwise adjustment is to increase voltage, maximum to 1.1 Ve. Due to the needs of the internal self-test circuit and non-zero start design, adjusting 3/4 clockwise circles does not have voltage output after the potentiometer is back to zero.
9. Voltage fine adjustment knob: When the potentiometer in the middle position adjustment range for the current value of between 3% and 8%
10. Main power switch: Avoid directly turning off high voltage by this switch. Please use the HV switch first.
11. HV switch: Dial up the HV switch to increase voltage. Turn off the switch before shutting off the power after test.
12. Fuse: AC inlet fuse. Please use the matching fuse current value
