Operation
WRIST STRAP TEST
1. While wearing a wrist strap, plug the wrist cord
into the wrist strap jack located on the face of the
Combo Tester.
2. Toggle the rocker switch to the right toward WRIST
STRAP.
3. Push down and hold the test switch until the test
results are displayed. Ensure that your finger
also makes contact with the metal ring around the
pushbutton when performing a test.
DO NOT touch any other metal while performing
your test as this will affect your results.
4. A “PASS” test result is indicated by illumination
of the green LED. A “FAIL LOW” test result is
indicated by illumination of the red LED. A “FAIL
HIGH” test result is indicated by illumination of the
yellow LED.
If your ESD test fails, check your wrist strap and
ensure that it is being worn correctly and/or needs
to be replaced.
NOTE 1: The Combo Tester may briefly display “FAIL
HIGH” once the test button is released at the conclusion
of a test. Residual voltage in the circuit’s capacitors
causes the test to continue for a split second after the
button is released.
NOTE 2: Failures may be caused by dry skin or minimal
sweat layer. For wrist straps, try using an approved
dissipative hand lotion such as
Menda Reztore™ ESD
Hand Lotion
to your wrist prior to use.
FOOTWEAR TEST
1. Toggle the rocker switch to the left toward FOOT
PLATE.
2. While wearing ESD footwear, place one foot on
the foot plate, and lift the second foot off the floor.
Make sure there is no wrist cord plugged into the
WRIST STRAP jack.
3. Push down and hold the test switch until the test
results are displayed. Ensure that your finger
also makes contact with the metal ring around the
pushbutton when performing a test.
DO NOT touch any other metal while performing
your test as this will affect your results.
