TECHNICAL BULLETIN TB-2099
AC Outlet Analyzer and Wrist Strap
Tester - Operation and Maintenance
The AC Outlet Analyzer and Wrist Strap Tester is available
in the following models:
Item Voltage Plug
98130 120V US
98131 220V UK / Asia
Instructions
Just plug AC Outlet Analyzer into an outlet to see if green
pass LED is illuminated, verifying orientation. For wrist strap
testing, plug wrist strap while worn into wrist strap test jack.
Figure 1. Desco 98130 AC Outlet Analyzer and Wrist
Strap Tester
By touching the Test Button on the tester, a person can
quickly and easily ensure that their wrist strap grounding
system contains adequate current limiting resistance and that
there is continuity from one’s skin to ground.
The tester detects poorly fitting, worn out, corroded or dirty
wrist straps. It can also be used to check the integrity of
the conductive path from sleeve-to-sleeve of ESD protective
garments.
“Typical test programs recommend that wrist straps that are
used daily should be tested daily.” (Handbook ESD TR20.20
section 5.3.2.4.4)
Made in America

Description
Desco’s AC Outlet Analyzer and Wrist Strap Tester is
an easy-to-use, low cost, plug-in tester. It is designed to
confirm the integrity of the resistance path from field service
personnel to ground. This is possible through wrist strap
grounding systems and the equipment grounding conductor.
When the AC Outlet Analyzer and Wrist Strap Tester is
plugged into an AC outlet, the green LED lights if the
outlet’s wiring is correct and the path to earth ground via the
equipment grounding conductor (the green wire) is intact.
The red LED lights if either condition is not met.
Use the AC Outlet Analyzer and Wrist Strap Tester to fulfill
the S6.1 Section 6.3.1 requirement. “The hot, neutral, and
equipment grounding conductor shall be verified to be in the
proper wiring orientation in accordance with the National
Electric Code (ANSIINFPA-70).” (Grounding ANSI ESD S6.1
section 6.3.1 Equipment Grounding Conductor)
Calibration
The AC Outlet Analyzer and Wrist Strap Tester is calibrated
to NIST traceable standards. Calibration may be performed
to insure that the tester is operating within limits. We
recommend annual calibration of our testers.

TESTING THE WRIST STRAP TESTER
PROCEDURE FOR ITEM 98130
A. LOW FAIL - Connect a 450 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 550 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 45 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 60 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.
PROCEDURE FOR ITEM 98131
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.
TESTING THE AC OUTLET ANALYZER (98130 ONLY)
NOTE: The following procedure should only be done by
someone familiar with voltage hazards. This procedure
does not apply to item 98131 because the United Kingdom
does not reference GROUND to NEUTRAL as the United
States does.
Isolate the ground plug from the AC Outlet Analyzer and
Wrist Strap Tester by inserting the tester into a “3 to 2” plug
adapter.
A. PASS OUTLET - Connect a 5 kilohm resistor @ 5%
tolerance across the Neutral Plug and
Ground Plug. The Outlet PASS LED
should remain illuminated until the
resistor is removed. This test
confirms the PASS point for the
neutral-to-ground resistance.
B. FAIL OUTLET - Connect a 12.5 kilohm resistor @ 5%
tolerance across the Neutral Plug and
Ground Plug. The Outlet FAIL LED
should remain illuminated until the
resistor is removed. This test
confirms the FAIL point for the
neutral-to-ground resistance.
