Single loop wrist strap monitor (manual switch)

Anti-static wrist strap online monitor manual

The wrist strap online monitor, which is made of high-precision electronic components, has the characteristics of high accuracy, fast response, strong anti-interference ability, small size, light weight, and simple use; it has automatic grounding system for the human wrist strap. The alarm function can monitor the working status of the anti-static wrist strap at any time, and it runs without noise. It can provide reliable protection for the wrist strap grounding system in the anti-static (personal) work area.

1. Performance description

1. Real-time monitoring of the operator’s wearing of the electrostatic wrist strap and the ground connection of the ground wire, and an automatic alarm immediately in case of abnormal conditions.

2. It is easy to use and can correctly judge the contact between the ground wire of the ground and the ground wire of the workbench.

3. It can be set according to design needs, generally set to 1.068-2.0MΩ (±5%), which conforms to international standards, and monitoring parameters can also be set freely. 4. Microcomputer chip control, no debugging, plug and play.

5. Good reliability and strong anti-interference ability.

6. High sensitivity. When the static discharge path fails for ≥0.1 seconds, the monitor will alarm.

2. Instructions for use

1. Install the anti-static wrist strap monitor under the console.

2. Connect one end of the ground wire (yellow-green) to the instrument and the other end to a ground wire that is reliably connected to the earth.

3. Plug one end of the power adapter into the power input interface, and the other end into the AC220V power supply, and press the power switch.

4. Wear the anti-static wrist strap tightly to make the metal sheet close to the skin, and insert the plug at the other end of the electrostatic wrist ring connection line into the INPUT hole.

3. Troubleshooting

1. Normal state: green light is on

① The electrostatic wrist strap is in good contact with the hand, the electrostatic wrist strap and the grounding wire are well grounded, and the electrostatic discharge of the human body is smooth.

② Working well, real-time monitoring of the electrostatic wrist strap.

2. Alarm state; when the alarm sound and the red light are on, it is the reason for the bad alarm state, implement countermeasures, the red light is on and the alarm sound

① The wrist strap is off, just wear the wrist strap

② Dry skin, use skin anti-static oil

③ The wrist strap is damaged, replace the wrist strap

④ The ground connection is not discharged properly, check the grounding system
