How to test anti-static wrist strap
Wearing an anti-static bracelet
1. The anti-static bracelet uses the metal block on the electrostatic ring that contacts the skin to release the static electricity generated by the human body to the ground through the lead of the anti-static ring. Therefore, only by wearing the anti-static ring correctly can the purpose of releasing static electricity be achieved.
2. When wearing an anti-static bracelet, you must ensure that the metal block in the anti-static bracelet contacts the human skin.
After wearing the anti-static bracelet, prepare an electrostatic bracelet tester and clip the alligator clip of the bracelet connection cable to the ground wire of the tester.
3. Tie the wrist strap tightly and press the metal touch panel of the tester. At this time, the corresponding indicator light of the tester will light up.
critical result
1. If the green "PASS" light is on and accompanied by a buzzer, it means that the wrist strap grounding system is good;
2. If the red "FAIL" light is on, there are two situations: one, the display tube shows resistance less than 800KΩ, which will have a great impact on human safety and should be stopped immediately.
On the other hand, if the wrist strap does not loosen the ground wire, it means that the ground resistance is greater than 9.9MΩ, exceeding the 1M-10M range specified for anti-static resistance, and you should stop using it.
