Ground Strap Testers

• Performs precision ground-strap resistance measurements, automatic upper/lower resistance tests
• Ideal for both wrist straps and heel straps
• Fail-safe design features automatic self-check
• Includes PASS/FAIL indicators, visible/audible alarms
• Complies with EOS/ESD and NAVSEA Standards

This precision Ground Strap Tester automatically measures the resistance of ground straps and clearly indicates whether or not the resistance is within the specified limits.

For ESD applications where the required strap resistance is 1 megohm, the tester uses a lower limit of 750 kilohms and upper limits of either 1.25 megohms (for the strap only) or 10 megohms (for the strap and the wearer). A two-position switch enables the user to select either the STRAP ONLY mode or the STRAP PLUS WEARER mode.

The Ground Strap Tester incorporates both visual and audible indicators and a unique fail-safe design with automatic self-check. Each time the tester is operated, the FAIL audio/visual indicators are momentarily activated prior to the actual test, ensuring that both the FAIL and PASS modes are working. When a defective strap is tested, the FAIL Red LED indicator will flash continuously and the audible alarm will continue to sound. When a good strap is tested, the FAIL Red LED will flash and the audible alarm will sound for approximately one half second; the PASS Green LED indicator will then light and remain lit for as long as the TEST button is depressed.

Portable Ground Strap Tester

• Incorporates upper and lower resistance tests
• Displays PASS/FAIL information on easy-to-read LED
• Provides an audible “Out of Spec” alarm

This Ground Strap Tester provides an inexpensive method for guaranteeing the integrity of wrist straps. This compact, automatic test unit checks the specified resistance limits of all types of wrist straps and other similar personnel grounding devices. A single banana-jack input connector accommodates industry-standard wrist straps. A belt clip is included; the case is made of tough ABS plastic.

Dual Upper Limits for Flexible Applications
The tester compares the measurement to preset lower (750 kilohms) and upper (1.25 or 10 megohms) resistance levels. A two-position switch located on the front panel enables the user to select either upper limit; use the 10 megohm limit for checking the condition of the wrist strap while on the wearer’s wrist, or the 1.25 megohm upper limit for checking the wrist strap alone.

The tester incorporates both visual and audible PASS/FAIL indicators and a unique fail-safe design with automatic self-check. Each time the tester is operated, the FAIL audio/visual indicators are momentarily activated prior to the actual test, ensuring that both the FAIL and PASS modes function properly. When a defective strap is tested, the red FAIL LED indicator and audible alarm are indicated.

The circuits and displays used are part of an efficient (low current) circuit design that enables the unit to operate from a single 9-volt alkaline battery for a period in excess of two years under normal use. The unit also contains a battery test circuit that continuously monitors the condition of the battery and warns the operator when it must be replaced. Complies with requirements of EOS/ESD Assoc. STD DS -1 3/85.
