The withstand voltage tester is an instrument to measure the withstand voltage strength. It can directly, accurately, quickly and reliably test the breakdown voltage, leakage current and other electrical safety performance indicators of various tested objects, and can be used as a high-voltage source to test the performance of components and the whole machine. LK withstand voltage tester product series is designed according to IEC, CSA, UL, JIS and other international and domestic safety standards, with withstand voltage output of 1kv-50kv and leakage current of 0-200mA. It is suitable for all kinds of household appliances, power switches, wires and cables, transformers, terminals, high-voltage bakelite appliances, motors, medical treatment, chemical industry, instruments and meters, as well as the safety withstand voltage and leakage current test of strong current system, and it is also an indispensable withstand voltage test equipment for scientific research laboratories and technical supervision departments.

1) Power switch;

2) Start button: when pressed, the test light is on, and the instrument outputs high voltage;

3) Reset button: when pressed, the test light is off, and there is no high-voltage output at this time;

4) Voltage adjusting button: adjust the output voltage, which is small in reverse and large in reverse;

5) Test lamp: when the lamp is on, it indicates that the high voltage has been started, and when the lamp is off, the high voltage is disconnected;

6) Over leakage lamp: when the lamp is on, it means that the tested object is broken down 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 indication;

10) Time timer: 1-99s timing adjustment, which can set the required test time value;

11) Leakage flow and selector switch: to switch the range of leakage current indicating ammeter, they are 0-2ma, 0-20mA and 100mA respectively according to the switch status;

12) Leakage current preset switch: press the preset switch to set the leakage current alarm value, release the preset switch, which will be in the test state under normal condition, and the leakage current value can be detected immediately through the "leakage current indicating ammeter";

13) Leakage current meter: according to the position of "leakage current range switch", the corresponding indication is 0-2ma, 2-20ma, 100mA;

14) Leakage current preset adjustment button: press the preset switch to set the leakage current alarm values of 0.3-2ma, 2-20ma and 100mA;

15) Timing switch: "on" means any adjustment within 99S; "off" means the timer does not work and is manual;

16) Remote control socket: plug in the remote control plug to remotely control the instrument through the switch on the high-pressure bar.

17) Grounding post: for connecting test grounding wire.

18) Voltage change-over switch: AC / DC change-over switch.
