The Desco Combo Tester X3 verifies the functionality of personnel grounding devices (wrist straps1, foot grounders, ESD shoes, smocks2). Three independent tests are performed simultaneously on the wrist strap and each foot. Green lights indicate a pass condition. Red and yellow lights plus an audible alarm indicate when the wrist strap and/or footwear (left or right) have failed. 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. The Combo Tester X3 is calibrated to NIST standards and includes a certificate.
