EVT-Pro Calibration Requirements

Rev - 1.0 / Page 54 / 10/10/2012

Any device which is used to measure and determine quantitative measurements for
the purpose of quality should be calibrated annually to certify results. This is typical
language used by any certifying body for ISO or other quality group such as NB or
ASME.

As  such  it  is  recommended  that  the  EVT  Pro  be  calibrated  annually  to
ensure  compliance  and  adherence  to  ASME  /  NB  and  other  standards
globally.
