There are no pre-specified minimum requirements when testing anti-static wrist straps
There are no pre-specified minimum requirements when testing anti-static wrist straps, but a good experience is: every time you wear an anti-static wrist strap or start another job, you must test it. The frequency of testing depends on the ESD sensitive devices you want to protect. If the equipment is expensive and controlled by the operator, frequent monitoring is required, but if the equipment is not particularly sensitive and relatively cheap, regular testing is sufficient.
When testing an anti-static bracelet, check the following points: make sure that the wrist strap is in close contact with the wrist; conductive fiber or metal/conductive material is close to the skin; the buckle on the metal buckle is suitable, and the buckle on the coil end is suitable . The connector must be firmly fixed, and the spring of the banana plug has good elasticity and is in close contact with the jack of the banana plug. Other things that should also be checked are: intermittent breaks in the coil (usually at the end), dirt in the belt, oil and solder shell (which will reduce the conductivity of the belt), it is possible to safely apply 1-5 pounds of voltage to the button buckle Tighten the metal buckle in the reel.
