Wrist strap testing:
If you are not using a continuous or a constant monitor, a wrist strap should be tested while being worn at least daily. This quick check can determine that no break in the path-to-ground has occurred. Wrist straps should be worn while they are tested. This provides the best way to test all three components: the wrist band, the ground cord (including the resistor) and the interface with the operator's skin. If the wrist strap tester outputs a FAIL test result, stop working, and test the wrist band and cord individually to find out which item is damaged. Replace the bad component, and repeat the test. Obtain a PASS test result before beginning work. 

Footwear testing:
If using a flooring / footwear system as an alternative for standing or mobile workers, ESD footwear should be tested independently at least daily while being worn. Proper testing of foot grounders involves the verification of the individual foot grounder, the contact strip and the interface between the contact strip and the operator's perspiration layer. If the footwear tester outputs a FAIL test result, stop working, and test the foot grounder and contact strip individually to find out which item is damaged. Replace the foot grounder. Obtain a PASS test result before beginning work.
