The SCS 770031 Combo Tester with stand and foot plate, 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.
