Accuracy note: Accuracy statement applies to use on a flat surface, with a zero and a
calibration performed near the thickness of the film to be measured, with an identical base
metal and with the meter stabilized at ambient temperature 18 to 28°C (64 to 82°F).
The accuracy of the reference films or any reference standards should be added to
measurement results.
