Tester
Description
SPI’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.
Instructions
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.
Resistance Limits
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)
The AC Outlet Analyzer and Wrist Strap Tester meets
ANSI/ESD S20.20-2007 Wrist Strap System Compliance
Verification test method per ESD TR53 in accordance with
S20.20 Table 2 lower limit 800 kilohms and upper limit of
<3.5 10E7 ohms.
"Typical test programs recommend that wrist straps that are
used daily should be tested daily.” (Handbook ESD TR
20.20 paragraph 5.3.2.4.4)
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.

features and components
TESTING THE WRIST STRAP TESTER
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 unitl 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 55 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
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.
