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 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.
Calibration
The Desco Combo Tester is calibrated to NIST
traceable standards. There are no user adjustments
necessary. We recommend that calibration be
performed annually using the Desco
07010
Calibration
Unit. It is a convenient product which allows the
customer to perform NIST traceable calibration on
single-wire personnel testers. The
07010
is designed
to be used on the shop floor at the workstation, virtually
eliminating downtime, verifying that the tester is
operating within tolerances.
