Product description
Wrist strap tester 498 is ideal in an ESD test or manufacturing environment. Anti-static wrist straps can fail to perform. ESD ground cords get stressed from use and can break open inside the insulation. Because proper wrist strap performance can't be see, they must be tested regularly. Professionals should test their wrist straps at least once per day. Depending on the quality standards at your company, more frequent testing may be necessary. This portable anti-static wrist strap tester is perfect for on the spot testing of wrist straps as part of your ESD quality control program.
Anti-static wrist strap tester 498 provides simple and reliable tests.
The operator wears the wrist strap band on their wrist.
Insert the banana plug on the end of the wrist strap ground cord into the jack located on the top of the wrist strap tester.
The operator then pushes the metal pushbutton on the wrist strap tester.
The tester measures the resistance of the ground path from the skin of the operator through the ground cord of the wrist strap.
A properly operating wrist strap will show a "GOOD" LED indication on the antistatic wrist strap tester. If either of the "LOW" or "HIGH" red LED's light, and the audible indicator sounds, then either the wrist strap or its ground cord is faulty.
If either fault is indicated, the included test ground cord (shown) can be used to isolate the fault to either the wrist strap itself, or the original wrist strap ground cord.
The faulty piece should be discarded and replaced with a new one.
