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.

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 footwear 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. Footwear test results can be improved
by taking a short walk to build a sweat layer for better
conductivity.
5. Repeat steps 2-4 for the second foot.
Maintenance
The Combo Tester requires little maintenance. There
are no user serviceable parts. If your meter requires
service beyond cleaning the test switch or foot plate,
please contact the factory.
Use a minimum of 80% isopropyl alcohol to clean the
test switch. Other cleaners are susceptible to leaving
residue.
BATTERY REPLACMENT
The low battery indicator flashes briefly every time
the unit is used. Replace the battery once the
indicator becomes constant during testing. Open
the compartment located on the back of the tester to
replace the battery. The tester uses one 9V alkaline
battery.
