Combo Tester X3 determines that the operator’s personal grounding devices (wrist straps, foot grounders, ESD shoes, smocks) are functioning correctly. Three independent tests are performed simultaneously on the wrist strap and each foot in less than 3 seconds. DIP switches may be accessed for test limit preferences. Access control to an ESD Protected Area can be further enforced by using the relay terminal on the Combo Tester X3 and connecting it to an electronic door lock or turnstile to grant access only to those who have passed their personal grounding device tests.
