Description
The SCS Combo Tester verifies the functionality of
an operator's wrist strap and footwear (footwear test
requires foot plate). It determines if an operator's wrist
strap and footwear will function correctly. A rocker
switch allows the operator to select a wrist strap or
footwear test. A green light indicates that the wrist strap
or footwear is passing. Red and yellow lights plus an
audible alarm indicate when the wrist strap or footwear is
failing. If failure occurs, the tester will also display if the
grounding device's resistance is too low or too high.
The Combo Tester may also be used to test smocks
or garments that feature a grounding mechanism for
operators using a coiled cord connection.
The factory test limits are set to:
Wrist Straps:
750 kilohms and 10 megohms
Footwear:
750 kilohms and 100 megohms
Limits meet the required limits for Compliance
Verification of ANSI/ESD S20.20 (Wrist Strap System
< 3.5 x 10
ohms and Footwear < 1 x 10
7
per ESD TR53).
The Combo Tester can be powered by a 9 volt battery or
the SCS
770034
(North America plug) and
inlet) power adapters (sold separately). A warning light
on the tester indicates when the battery power is too low
and affecting the test results.
Each Combo Tester is calibrated with accepted
procedures and standards traceable to the National
Institute of Standards and Technology (NIST) and
includes a NIST certificate.

Per ANSI/ESD S20.20 section 7.4 "A Compliance
Verification Plan shall be established to ensure the
Organization's fulfillment of the technical requirements
of the ESD Control Program Plan. Process monitoring
(measurements) shall be conducted in accordance
with a Compliance Verification Plan that identifies the
technical requirements to be verified, the measurement
limits and the frequency at which those verifications shall
occur. The Compliance Verification Plan shall document
the test methods and equipment used for process
monitoring and measurements. ... The test equipment
selected shall be capable of making the measurements
defined in the Compliance Verification Plan."
Per ANSI/ESD S1.1 Annex A.3 Frequency of System
Testing "The wrist strap system should be tested daily to
ensure proper electrical resistance."
Per ESD Handbook ESD TR20.20 section 5.3.2.4.2
Additional User Wrist Strap Testing "Proper testing of
the wrist strap includes the resistance of the groundable
point on the end of the cord, the cord itself, the resistor,
the cord-to-cuff snap connector, the resistance of the
interface of the cuff, the cuff/wrist interface, and the
resistance of the person between the wrist and the hand
that contacts the test electrode."
Per ESD Handbook ESD TR20.20 section 5.3.2.2.2
Wrist Strap Ground Cord "At first glance, the ground cord
appears to be a relatively simple assembly. However,
the design requirements are considerable, given the
wide range of user applications and the durability
requirements of constant tugging, flexing, and dragging
over the edge of workstation tops and equipment
chassis."
