What should you pay attention to in the use of anti-static shoes and wristbands?
(a) Do not disconnect when using the wrist strap, otherwise the grounding effect will be lost. The primary question of the use of various wristbands is the open circuit, sometimes temporary, sometimes broken for a long time, so that the grounding effect is lost. Some people use the wristband detector to measure the on/off condition, and some use the monitoring instrument to measure the open circuit and the resistance of the wristband.
(b) The wristband is not fastened, and the contact resistance between the human skin and the wristband becomes large.
(c) The resistance of some wristbands is the strap itself. When the belt touches the ground, its resistance is greatly reduced, which may constitute a risk of electric shock to the human body.
(d) Some wristbands that claim to be wireless are far less effective than wired ones.
(e) Anti-static shoes should have anti-static socks/insoles when worn, and work on anti-static ground to make the static electricity brought by the human body to the earth. Any one of the resistances that are too large or broken will cause the human body to be harmed. Static electricity. Therefore, some important human body resistance testers should always detect whether the shoes/socks/insoles worn by the human body and the total resistance of the human body can meet the need for leakage static electricity.
(f) The wrist strap is connected to the ground using a special grounding wire with a socket. It cannot be clamped to the metal body on the table or table side, because the resistance of these metal bodies to the ground can be large.
(g) Always check the resistance of the wristband.
