Operation
PERFORMING A WRIST STRAP TEST
1. Use the wrist strap test jack to ground the operator’s
wrist strap.
2. While wearing the wrist strap, touch the tester’s test
plate to determine if the operator’s wrist strap will
act as a path-to-ground and ensure the presence of a
current-limiting resistor in the wrist strap.
A “PASS” test result is indicated by illumination of the green
TEST LED. A “FAIL” test result is indicated if the LED does
not illuminate.
If your ESD test fails, check your wrist strap to ensure it is
being worn correctly and/or needs 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.
The AC Outlet Analyzer and Wrist Strap Tester may also be
used to test smocks or garments that feature a grounding
mechanism for operators using a coil cord connection.
Calibration
TESTING THE WRIST STRAP TESTER
A. LOW FAIL -
Connect a 675 kilohm resistor @ 5%
tolerance between the Wrist Strap Test
Jack and the Test Plate. The Wrist Strap
Test LED will momentarily illuminate then
turn off. This test confirms the LOW FAIL
point.
B. LOW PASS -
Connect a 825 kilohm resistor @ 5%
tolerance between the Wrist Strap Test
Jack and the Test Plate. The Wrist Strap
Test LED will remain illuminated until the
resistor is removed from the Test Plate.
This test confirms the LOW PASS point.
C. HIGH PASS -
Connect a 32 megohm resistor @ 5%
tolerance between the Wrist Strap Test
Jack and the Test Plate. The Wrist Strap
Test LED will remain illuminated unitl the
resistor is removed from the Test Plate.
This test confirms the HIGH PASS point.
D. HIGH FAIL -
Connect a 40 megohm resistor @ 5%
tolerance between the Wrist Strap Test
Jack and the Test Plate. The Wrist Strap
Test LED should not illuminate. This test
confirms the HIGH FAIL point.

Installation
PERFORMING AN AC OUTLET TEST
Plug the AC Outlet Analyzer into a proper electrical outlet.
The unit will indicate the condition of the electrical outlet via
the Outlet LEDs.
• The green LED will illuminate if the outlet’s wiring
is correct and the path to equipment ground via the
equipment grounding conductor is intact.
• The red LED will illuminate and the alarm will sound
if the outlet’s wiring is incorrect and/or the path to
equipment ground via the equipment grounding
conductor is not intact.
