Anti-static wrist strap tester HZR-171

  • How to use the wrist strap tester:

    • The operator performs the test while wearing the wrist strap as normal.
    • Insert the banana plug end of the wrist strap ground cord into the jack located on the front of the wrist strap tester.
    • Push and hold the metal button on the wrist strap tester for several seconds.
    • The tester measures the resistance of the ground path from the skin of the operator through the wrist strap and ground cord.
    • The proper resistance will provide an “OK” LED indication on the wrist strap tester.  If either the RED “FAIL LOW” or YELLOW “FAIL HIGH” LED’s light, and the audible indicator sounds, then the wrist strap (or the ground cord) should be replaced.
