Calibration
The Vermason Portable Wrist Strap Tester is calibrated
to NIST traceable standards. There are no user
adjustments necessary. We recommend that calibration
be performed annually using the Charleswater
99090
Calibration Unit. It is a convenient product which allows
the customer to perform NIST traceable calibration on
single-wire personnel testers. The
99090
is designed
to be used at the workstation, virtually eliminating
downtime, verifying that the continuous monitor is
operating within tolerances.
