TECHNICAL BULLETIN TB-3034

Combo Tester X3

Installation, Operation and Maintenance

Made in the

United States of America

Per ANSI/ESD S20.20 section 7.3 “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 section 6.1.3 Frequency of Functional

Testing. “The wrist strap system should be tested daily to

ensure proper electrical value.”

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.”

“Compliance verification should be performed prior to each

use (daily, shift change, etc.). The accumulation of insulative

materials may increase the foot grounder system resistance.

If foot grounders are worn outside the ESD protected area

testing for functionality before reentry to the ESD protected

area should be considered.” (ESD SP9.2 APPENDIX B -

Foot Grounder Usage Guidance)

“Compliance verification records shall be established and

maintained to provide evidence of conformity to the technical

requirements.” [ANSI/ESD S20.20-2007 section 7.3]

Description

The Desco Combo Tester X3 verifies the functionality

of an operator’s wrist strap and footwear. It determines

if an operator’s wrist strap and footwear will act as a

path-to-ground and ensures the presence of a current-limiting

resistor in the grounding devices. The operator’s wrist

strap and footwear will test simultaneously with no need for

separate tests. Green lights indicate that the wrist strap

and footwear are passing. Red lights and an audible alarm

indicate when the wrist strap and/or footwear (left or right)

are failing. If failure occurs, the tester will also display if the

grounding device’s resistance is too low or too high.

The factory test ranges are set to:

Wrist Straps:

Footwear:

750 kilohms - 10 megohms

750 kilohms - 35 megohms

Each Combo Tester X3 is calibrated with accepted

procedures and standards traceable to the National Institute

of Standards and Technology (NIST) and includes a NIST

certificate.
