Installation, Operation and Maintenance
Description
The Desco Combo Tester X3+ verifies the functionality
of personnel grounding devices (wrist straps
1
, foot
grounders, ESD shoes, smocks
2
). Three independent
tests are performed simultaneously on the wrist strap
and each foot. Test prompts and test results with
resistance measurements are displayed on the 5 inch
color touchscreen display. The administrator menu in
the tester’s software 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.
