ESD Wrist Straps are often the first line of defense in protecting static sensitive product from the damaging effect of an electrostatic discharge.   Many variables effect the frequency of this testing and itís generally decided and written into internal program guidelines. Most clients that donít use our ESD constant monitors will test once in the morning and often after lunch and throughout the day.

The SI-500 ESD Wrist Strap Tester strikes the perfect balance between cost, performance and longevity. This robust yet small 2.5 x 3.75 x 1 inch tester features an easy to comprehend Hi-Fail / Low-Fail / Pass set of LED readouts and a built in audio signal that quickly lets the technician know that their test is complete and their strap is in compliance. The unit features inputs for THREE of the most common wrist strap terminations accepting a banana jack, a 3/8 inch female snap and a mini screw type fastener/lug (for the attachment of an alligator style termination).

The SI-500 is powered by an easy to change 9 volt battery that will provide 1000's of test without the need for a battery replacement. The test unit also provides a Battery Low LED indicator for optimum reliability. Each unit is supplied with a certificate of calibration valid for one year. Recertification may be accomplished by the end users or independent third party testing labs.

The SI-500 is Warranted for 1 year from the original date of purchase and may also be used to test primary grounding smocks and smock cords.

  • Triple inputs handle multiple types of single conductor (standard) wrist strap ground terminations. Test wrist strap, wrist strap cord, and the conductivity of the technicianís skin in one fast easy to comprehend push of a button.


DIRECTIONS FOR USE: Remove battery cover, install 9 volt battery (enclosed with each order). Attach ESD wrist strap termination to one of three input ports. Place strap on wrist - ensure firm contact. Push test button. Review results.

Hi-Fail alarm (Yellow LED - No audible signal): Compromised strap to skin contact, dry skin, a faulty wrist strap cord or a compromised ESD wrist strap.

Lo-Fail Alarm (Red LED - No audible signal): 1 megohm safety resistor that is normally built into your wrist strap cord has lost it's resistivity and may present a safety hazard - especially when working with high voltage power sources. Replace wrist strap cord and retest.

Pass (Green LED - Audible GO Signal indicates test is complete): Log in.

Bat-Low (Red LED): Replace Battery.
