Test (UT) deviation

Hi, Just would like to know how do you calculate UT thickness(spot) readings deviation for accuracy. Some people are telling me to take the (Max Reading - Min. Reading) / Average reading.
While some are practising the standard deviation formula in mathamatics.
Just would like to know the actual practice so that I can get an analysis of % deviation in thickness spot readings.

thanks guys

Next generation for Phased Array UT is here now with FMC/TFM! Have higher resolution imaging, impr
...
oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
