Test ESD Wrist Straps and Ground Cords

Factory assembled and ready to use, the portable anti-static wrist strap tester model HZR-171 is ideal for on the spot testing of anti-static straps and ground cords as part of your ESD compliance verification program.

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.

Specifications

• storage temperature  5°F to 140°F (-15°C to 60°C)
• relative humidity: 0% to 90%
• accuracy: ±5%
• net weight: 5.2oz (145g)
• dimensions: 2.8in W  x   3.54in L  x  1.1in T  (7.1cm  x  9.0cm  x  2.8cm)
• operating voltage: ≥ 6.5 volts  ≤ 9 volts  (low battery indicator set at 6.5V)

The operator wears their wrist strap as they would in normal working conditions.
- Insert the banana plug into the jack located on the front of the wrist strap tester.
- Push the rectangular silver button 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 give an "OK" LED indication on the wrist strap tester.
- If either RED "FAIL LOW" or YELLOW "FAIL HIGH" LEDs light, and the audible indicator sounds, then the wrist strap should be discarded and replaced with a new one.
