The VER-28400 is a Wrist Strap Tester used to test per EN 61340-5-1 Annex A wrist strap test method. The operator shall wear the wrist strap in the normal position and plug the free end of the cord into the test apparatus. The hand contact plate shall be pressed to verify that the wrist strap system resistance is within acceptable parameters. The test apparatus can be an integrated, commercially available tester. Being a portable battery powered tool, it is perfect for small labs or for a supervisor to spot-check workers and/or ensure compliance. When the wearer of a wrist strap plugs in their coiled cord and touches the metallic surface of the wrist strap tester, a path for current flow is completed from the wearer's skin, through the wrist strap. This action will cause the green 'test good' LED to light as long as the resistance of the circuit path is between 800kR and 10R.
