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 Organizations 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 Figure 1. Desco Combo Tester X3 and Dual Foot Plate 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 Description of the cuff, the cuff/wrist interface, and the resistance of the The Desco Combo Tester X3 verifies the functionality person between the wrist and the hand that contacts the test of an operators wrist strap and footwear. It determines electrode. if an operators wrist strap and footwear will act as a path-to-ground and ensures the presence of a current-limiting Per ESD Handbook ESD TR20.20 section 5.3.2.2.2 Wrist resistor in the grounding devices. The operators wrist Strap Ground Cord At first glance, the ground cord appears strap and footwear will test simultaneously with no need for to be a relatively simple assembly. However, the design separate tests. Green lights indicate that the wrist strap requirements are considerable, given the wide range of user and footwear are passing. Red lights and an audible alarm applications and the durability requirements of constant indicate when the wrist strap and/or footwear (left or right) tugging, flexing, and dragging over the edge of workstation are failing. If failure occurs, the tester will also display if the tops and equipment chassis. grounding devices resistance is too low or too high. Compliance verification should be performed prior to each The factory test ranges are set to: use (daily, shift change, etc.). The accumulation of insulative materials may increase the foot grounder system resistance. Wrist Straps: 750 kilohms - 10 megohms If foot grounders are worn outside the ESD protected area Footwear: 750 kilohms - 35 megohms testing for functionality before reentry to the ESD protected area should be considered.
