Description
The Desco Europe AC Outlet Analyser and Wrist Strap
Tester verifies the proper wiring of AC outlets, provides
a verified ground point, and tests the path-to-ground
integrity of an operator's wrist strap. Visual and audible
indicators display pass and fail conditions for the
outlet and pass condition for the wrist strap. When
plugged into an AC outlet, the green LED illuminates
to confirm that both the outlet's wiring is correct and
the path-to-equipment ground via the equipment
grounding conductor is intact. The banana jack provides
a grounding point for wrist straps. An operator's
path-to-ground may be verified by touching the test
switch while wearing a wrist strap connected to the AC
Outlet Analyser and Wrist Strap Tester.
The factory test ranges are set to:
Wrist Straps: 750 kilohms and 35 megohms

"Wrist straps should be tested periodically. The
frequency of testing, however, is driven by the amount
of usage, wear and ESD risk exposure that can occur
between tests. For example, what is the quantity of
product handled between test periods?
Because wrist straps have a finite life, it is important to
develop a test frequency that will guarantee integrity
of the system. Typical test programs recommend that
wrist straps that are used daily should be tested daily.
However, if the products that are being produced are
of such value that a guarantee of a continuous, reliable
ground is needed then continuous monitoring should be
considered or even required." [IEC TR 61340-5-2 user
guide wrist strap clause 5.3.3.4.2.9 test frequency]
