Description
The Desco Combo Tester 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.
