DUAL INDEPENDENT FOOTWEAR AND WRIST STRAP TESTER
Installation and Operating Instructions
The Desco EMIT Dual Independent Footwear and Wrist Strap Tester is designed to test
personal grounding devices, wrist strap and ESD footwear, to satisfy the requirements and
the recommendations of the ESD Association.
Per ANSI/ESD S20.20 Paragraph 6.2.2.2 Personnel Grounding Guidance “A log should be
maintained which verifies that personnel have tested their personal grounding devices. (Wrist
Straps and ESD Footwear)”
Per ESD- S1.1 paragraph 6.1.3 Frequency of Functional Testing “The wrist strap system
should be tested daily to ensure proper electrical value.”
Per ESD Handbook TR 20.20 paragraph 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 TR 20.20 paragraph 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.”
