Change cal.values
The gloss values of the calibration
standard in the holder included
with delivery are saved in the
measuring device. During
automatic calibration, this data is
assigned to the standard in the
holder.
In some cases it will be necessary
to enter data for a new calibration
standard, for example if the
previous standard has been
damaged or scratched.
Calibration and Autodiagnosis 15
After the zero setting has been
performed, the display „Air“ will
appear. To proceed with this, hold
the instrument in midair and press
the operate button.
The successful calibration is
confirmed in the display (OK). The
instrument returns to the selection
menu Calibration.
Note:
The film thickness measurement is
also influenced by the basis metal.
It is therefore advisable to perform
the zero calibration on the un-
coated metal which is used for the
object to be measured.
In this case place the instrument
on your original substrate instead
of on the supplied metal plate.
