Abstract:
Apparatus for on-site testing of wrist straps or shoe straps of the type d to prevent the buildup of electrostatic charges on the body and clothing of a worker engaged in handling charge-sensitive electronic devices. The worker wearing a grounding strap connects the grounding strap to a terminal on the tester and touches a touch pad on the apparatus. The tester incorporates the resistance of the grounding strap and the worker wearing the strap into a voltage divider. If the incorporated resistance is within acceptable limits, an indicating lamp is lighted to show that the grounding strap is working properly. An indicating signal may also be coupled to a computer for automatic recordkeeping.
