Operation Interface Introduction
1 Display: 12.1-inch industrial touch screen;
2 Communication: low-voltage pulse method pulse signal output interface, high-voltage flashover method sampler receiving signal input interface;
3 Grounding: safety grounding terminal;
4 Power indicator: indicates the internal battery power, 4 grid display;
5 USB-1: external wireless network card and USB communication device;
6 USB-2: external wireless network card and USB communication device;
7 Power switch: "I" position, use AC 220V power supply to power the system;
"II" position, use internal battery to power the system; when the "power socket" is connected to AC 220V power supply, it also charges the battery;
"O" position, turn off the system power;
8 Power socket: instrument working power, AC 220V connection port;
9 Fuse: AC 220V power supply system fuse installation place;
10 Self-test: lower computer transmits signal;
11 On/off: turn on and off the working power of the industrial computer;
12 Amplitude: When collecting waveforms, adjust the amplitude knob to change the amplitude of the collected waveform;
13 Indicator light: Indicator light reflecting the test method;
14 Displacement: When collecting waveforms, adjust the displacement knob to change the height of the baseline of the collected waveform
