gauge to be tested without contributing to the
statistical calculations.

For the 2-POINT, ROUGH and SPECIAL
SUBSTRATE calibration methods
Step 2
requires
readings to be taken on a thin standard value
instead of on an uncoated base.

Repeating the reading will display the average. This
is particularly useful for rough surfaces as it allows
variations in the surface to be accounted for in the
calibration adjustment, therefore improving the
accuracy of the gauge.
