Now you can easily and reliably restrict the entry of personnel without valid personnel grounding into EPAs (ESD Protected Areas) by using a Combo Tester.
The system consists of a tester (combo tester) to validate the wrist straps and footwear, which is connected to the Access Control (magnetic lock) of the Door. When personnel enter the EPA, they need to test their wrist strap/ESD footwear. If the resistance of the Wrist strap / ESD footwear is within acceptable range as per the ANSI ESD S20.20 standard, the door is opened by release of the Magnetic Lock on the door. The instrument shows the result on a PASS or FAIL Basis.
