Wrist straps and ESD footwears are the first line of defence against electrostatic charge build up on the human body. They are designed to carryaway this charge as soon as it is generated. At the same time the wrist strap/footwear must remain electrically safe for the user. Thus, it isimportant to test every wrist strap/footwear regularly.In order to protect sensitive electronic components, the maximum wrist strap resistance should not be more than 10 meg ohms and Footwear resistance should not be more than 35 Mega ohms. On the other hand, the resistance should not be less than 0.75 Mohm as protection to the wearer from dangerous levels of voltage and current flow.
This COMBO TESTER is a combination Wriststrap & DUAL footwear tester whichchecks these parameters under actual realtime operating conditions. Thefootwear section gives a warning if either of the Footwear is defective.
