5.1 Calibration
Due to mechanical wear in use, changes
in the test environment, with a different
calibration of substrate material will be
to the gauge to bring a certain error,
appropriate calibration can improve its
accuracy of measurement.
The gauge is designed with three levels
of calibration methods, zero-calibration
one-point calibration and two-point
calibration.
5.1.1 Zero-calibration
There are two ways for zero-calibration:
measuring calibration and menus
calibration.
1) Measuring zero calibration
