There are no pre-defined minimum requirements when testing an antistatic wrist strap, but a very good experience is: Test it every time you wear an antistatic wrist strap or start another job, the frequency of the test depends on The ESD-sensitive device you protect fully, if the device is quite expensive and controlled by one operator, a regular monitor is necessary, but if the device is not particularly sensitive and relatively inexpensive, then regular testing is sufficient. There are a few things you should check when testing an antistatic wrist strap: make sure that the antistatic wrist strap is in close contact with the wrist; conductive fibers or metal/conductive materials are in close contact with the skin; the snaps on the metal buckle are suitable, the coil ends The snap connector should be tightly fastened, the banana plug spring is elastic, and the banana plug plug is in tight contact. Other things to look at are: intermittent interruption in the coil (usually at the end), dirt, oil and welding on the strap The inner casing (which will reduce the conductivity of the belt) is safe for applying a 1-5 lb. tension to the snap on the metal buckle in the coil.
