The composition of the front panel of the AC and DC withstand voltage tester

1) Power switch
2) Reset button: when pressed, the test light is off, and there is no high voltage output at this time;
3) AC-DC conversion switch: when it pops up, it is AC test; when it is pressed, it is DC test;
4) Start button: when pressed, the test light is on, and the instrument outputs high voltage at this time;
5) Voltage regulator: adjust the output voltage, the counterclockwise is small, and the clockwise is large;
6) Leakage current preset adjustment button: Press the preset switch to continuously set the leakage current alarm value 0.3~2mA/2~20mA;
7) Leakage current preset/test switch: press the preset switch, it is the preset state, window B shows the leakage current alarm value; pop up the preset switch, it is the test state, window B shows the actual detected leakage current value;
8) Leakage current range selection switch: switch the leakage current indication ammeter range;
9) Remote control socket: plug in the remote control plug, and the instrument can be controlled through the switch on the high voltage rod.
output for remote control.
10) High voltage output: DC high voltage output;
11) Test light: When the light is on, it means that the high voltage has been activated, and when the light is off, the high voltage is disconnected;
12) High voltage output: AC high voltage output;
13) Grounding post: used to connect the test grounding wire;
14) High-voltage output meter head: it can monitor the high-voltage output situation intuitively;
15) Time timer: 1~99 seconds timing adjustment, you can set the required test time value;
16) Timing switch: Press the timing test switch and adjust it arbitrarily within 99 seconds; when it pops up, the timer does not work and is manual;
17) Time display window: When the timer is turned on, the high-voltage output will be automatically cut off after the output reaches the set time;
18) Super-leakage light: When the light is on, it means that the object under test breaks down and the super-leakage is unqualified;
19) Leakage current display window: According to the position of "leakage current range switch", the corresponding indication is 0~2mA/2~20mA;
20) Voltage display window: output voltage value display;
