Anti-static wrist strap alarm function
Anti-static wrist strap alarm function, Shenzhen Haiwei Dahang Technology Co., Ltd. specializes in the production of anti-static wrist strap alarm, which is mainly to monitor the working status of the wrist strap worn by the staff, and continuously monitor the wrist strap. It is mainly affected by the static resistance of the staff's own body resistance and the working environment (anti-static floor, anti-static shoes, work clothes, table mats, chairs, etc.), and the fine-tuning is adjusted to make it work normally.
One to one alarm
The anti-static wrist strap alarm has a small measuring resistance of 800K ± 10% ohm. The detection method is as follows: adjust the fine adjustment of the online monitor to the right end of the *, connect the ground wire and the power supply, the red light flashes, accompanied by an alarm sound, connect one end of the adjustable resistance tester to the ground wire, and the other end and the wrist With the jack connection, then slowly slide the adjuster to turn the red light into a green light, the alarm sound disappears, and the resistance value obtained is the small range of the online monitor.
One for two alarm
Anti-static wrist strap alarm * Large measuring resistance is 2M. Do not insert the wrist strap, directly connect the ground wire, adjust the fine adjustment to the left, you can not consider the green light when the air is displayed, because the body's own body resistance impedance is about 1M, the impedance of the wrist strap is 1M ± 5%, other static electricity The impedance brought by the measure will not be greater than 1M.
In the normal working situation, the staff wears a wrist strap to adjust the fine adjustment, and adjusts the fine adjustment when the red light turns into the green light's critical point, and the adjustment is completed.
If there is a problem with this instrument, the fine adjustment will be out of control when the fine adjustment is adjusted, and it will not work normally.
