The use and technical requirements of the wrist strap online tester

Wrist strap online testerIt is an electrostatic protection device that can effectively monitor the anti-static wrist strap. The main purpose is to monitor whether the wrist strap is not worn properly and whether it is damaged, because the wrist strap that is too loose or broken will lose the electrostatic protection effect, resulting in the loss of the anti-static function of the wrist strap, thereby causing static electricity hazards. It can be checked by the wrist strap online tester. If the above-mentioned problems occur, the device will give an alarm, thus ensuring the reliability of the human body’s static electricity being released to the ground through the wrist strap.

Most of the wrist strap online testers currently on the market use DC power supply. There are generally three indicator lights on the appearance of "1ow", "high" and "pass or good".

Generally speaking, when the measured resistance R> 10MΩ, the tester"high” indicator will light up, and there will be a buzzer when it lights up; when the measured resistance is 800kΩ< r<="" ;="" 10mω,="" or=""><>< 10mω,="" the="" “pass”="" or="" “good"="" indicator="" of="" the="" wrist="" strap="" online="" tester="" is="" on;="" when="" the="" measured="" resistance="">< 800kω="" or="">< 750kω,="" the"low"="" indicator="" of="" the="" tester="" will="" light="" up="" and="">
