~II、Description
The wrist strap tester is a complete personal ground test system. The tester will
verify the connections while the strap is still on. The operator’s wrist Yellow LED and an
audible alarm indicate faulty connections (HI Fail ). Red LED and an audible alarm
indicate Low resistance or failed resistor (LO Fail), Green LED indicates proper
grounding ( OK ). Test parameters are factory set to pass 800K ~10M or 900K~35M ohms,
but are adjustable to match your own specifications. The unit comes equipped with a 9 volts
battery. The test verifies that a continuous path between the operators, wrist strap and ground
cord exit. With a test voltage of 9 volts DC. The tester is specially designed to perform this
test without harm to the operator.
Ⅲ、Operating Instruction -
While wearing the writ strap, plug the banana plug end of the cord into jack.
Lightly press the metal touch button marked “ PUSH ON” so that the unit activates.
Lighting of the green “ OK” LED indicates that the wrist strap and ground cord assembles
are functioning properly.
If either Red “ LOW FAIL “ Or Yellow “ HI FAIL “ LED light and the audible indicator
sound should check the wrist strap assemble immediately.
