What should be paid attention to in the use of anti-static shoes and wrist straps
(a) It is not allowed to disconnect when using the wrist strap, otherwise the grounding effect will be lost. The primary problem in the use of various wristbands is open circuit, sometimes temporary, sometimes long-term disconnection, which makes the grounding effect lost. Some people therefore use a wristband detector to measure its on-off status, and some use a monitoring instrument to measure the open circuit and resistance of the wristband.
(B) If the wristband is not fastened tightly, the contact resistance between the human skin and the wristband becomes larger
(C) The resistance of some wrist straps is the strap itself. When the strap touches the ground, its resistance is greatly reduced, which may pose a risk of electric shock to the human body.
(D) Some wristbands claiming to be wireless are far less effective than wired ones.
(e) Anti-static shoes should be worn with anti-static socks/insoles, and work on the anti-static ground to make the static electricity carried by the human body lead to the ground. Any excessive resistance or disconnection will cause harm to the human body Of static electricity. Therefore, in some important things, there should be a human body resistance tester to check whether the shoes/socks/insoles worn by the human body and the total resistance with the human body can leak static electricity at any time.
(F) The wrist strap is connected to the ground using a special grounding wire with a socket. It cannot be clamped on the table or the metal body beside the table because the resistance of these metal bodies to the ground can be very large.
(G) Always check the resistance of the wristband.
