Equipment Required
•Resistance Substitution Box (RSB) – 630 KΩ to 103 MΩ (minimum range) ± 1% or discrete resistors ± 1%, using resistor values as indicated in the tabled below.
•Lead wires – As required to connect between RSB and the 3M™ Shoes and Wrist Strap Tester 747.
•3M™ Copper Foil Tape with conductive adhesive or equivalent (4" L x 1" W recommended).
Test Set-Up
Apply a strip of copper foil tape to the unit’s “Touch Panel” as shown in Fig. 1, leaving a short tab for the purpose of attachment of a test lead. To prevent the copper foil tape from curling during removal of the release liner, peel the release liner from the copper foil tape.
Testing Wrist Strap Ranges
Connect the reference resistor to the “Wrist Strap Connector” and the tab of the Copper Foil Tape on the Shoes and Wrist Strap Tester 747 as shown in Figure 1.
