Two-point calibration
In measurement mode (screen displaying “----”) press and hold
“MODE” button for 2 second until “F-0” in displayed.
This is zero point of calibration.
Perform a measurement on uncoated bare metal plate for which
you’re calibrating. While the result of the measurement is
displayed, quickly press and release “PWR” button.
The screen will now display “F-1” - second point of calibration.
Perform another measurement on the same base metal plate,
now with the sample coating of known thickness.
While the measurement is displayed, select the right coating
thickness by pressing “MODE” and “UNIT” buttons and press and
release “PWR” button once done.
The screen will now display “8888” and 2-point calibration is
complete.
Double check the accuracy of calibration by performing
measurements on base metal plate with and without the coating.
If the calibration was unsuccessful, reset previous calibration
results by pressing and holding “UNIT” button for 2 seconds, while
the screen is displaying “----”.
