result is being displayed, shortly press the or
buttons to adjust the displayed thickness of the measured coating,
and shortly press the button to save the calibration. The
display will show "8888", indicating that the calibration has been
successfully saved.
Verify that the calibration is correct by repeating the measurement
of the metal substrate with and without the sample coating. If
unsuccessful, repeat the calibration.
Six-point calibration
This calibration is available in "P" measurement mode and will be
required when measuring coatings on substrates whose
properties differ from standard substrates, or for more accurate
measurements in a given range.
The new device's calibration is identical to the factory calibration.
For calibration, a metal base and 5 plates of known thicknesses
are required (not included in the set). All calibration points must
be evenly distributed throughout the measuring range.
F-0 (point 0) - Base without a coating (zero).
F-1 (point 1) - Plate with a thickness of 80-300µm (3-12 mils).
F-2 (point 2) - Plate with a thickness of 400-800µm (16-31 mils).
F-3 (point 3) - Plate with a thickness of 900-1800µm (36-70 mils).
