of the green LEDs. A “FAIL LOW” test result is
indicated by illumination of the red LEDs. A “FAIL

If your ESD test fails, check your wrist strap
and footwear to ensure that they are being worn
correctly and/or need to be replaced.
NOTE: 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
results can be improved by taking a short walk to build a
sweat layer for better conductivity.
The Combo Tester X3 may also be used to test smocks
or garments that feature a grounding mechanism for
operators using a coiled cord connection.
