The working principle of the wrist strap online monitor
The wrist strap online monitor is mainly used to monitor the working condition of the anti-static wrist strap containing 1M ohm.
1. Debugging method:
1. The ground wire and power supply of the online monitor with the wrist strap are installed as required
2. Connect one end of the debugger containing 1.4M ohm to the ground wire, and insert the other end into the wrist strap jack of the instrument. Then turn on the monitoring switch to debug, and use a small pen to debug the fine adjustment of the online monitor. When the red light is flashing and accompanied by the alarm sound, it is necessary to debug again. Turn the fine adjustment slightly to adjust to the zero boundary point of the red light and the green light. When the green light is on, the regulator test is completed. You can perform work operations.
3. After the debugging is completed, it can be known that the smaller the monitoring range, the higher the accuracy of the instrument. On the contrary, the larger the debugging range, the accuracy of the instrument will decrease.
2. Working conditions:
1. When the human wrist strap grounding system is working normally, there is no sound and the green light is on
2. When the grounding system of the human wrist strap is disconnected: there is a buzzing sound and a red light flashing.
3. Specifications:
1. Output: AC 220V
2. Output: DC 6V
3. Power consumption: 1.8W
4. Accuracy: ±5%
4. Features:
1. High precision, fast response speed, strong anti-interference ability, small size, light weight and simple use.
2. There is an automatic alarm function for the human wrist strap grounding system, which can monitor the working status of the anti-static wrist strap at any time, and it runs without noise, and can monitor the wrist strap grounding system in the anti-static (personal) work area
