Long-term memory
The long-term memory contains all the measured values that were saved there from the short-
term memory via the Save option.
To call up the stored measured values, proceed as described in the menu.
Navigate to the desired view as described in chapter 7.3
24 measured values are listed per page. Press the
"②
Down" key to call up the other pages and
the graphic display. Press the
"①
Up" key to scroll back one page.
In the list, the min and max values are marked by red numbers.
The graph shows a bar chart with the limit value setting. The measured values that are outside
the set limit values are shown with a red bar.
In the header, the unit of measurement, the average value and the number of measurements are
shown.
Press the key
"③
On / Off, Menu" to return to measuring mode.

Calibration
In order to ensure the accuracy of the measurement, it is necessary to calibrate the meter.
Before each measurement, carry out a control measurement on the calibration standard without
and with a foil of defined thickness. If there are deviations in the accuracy from the technical data,
carry out at least one zero and one offset calibration. After resetting the meter to factory settings
or when the system has not been used for more than 10 days, a base calibration should also be
performed.
Always use the calibration standard corresponding to the base material of your measurement
object for calibration.
7.8.1
Base calibration
For a base calibration, prepare a calibration standard and the calibration foils with increasing
thicknesses.
Navigate to the "Base calibration" menu option as described in chapters 7.2and 7.3 and open it.
Follow the instructions on the display and start measuring on the calibration standard without a
foil. You will then be prompted to perform one measurement after the other on a film with a
thickness of approx. 52, 105, 262, 490, 991 and 1486 µm. A beep means that the next
measurement is due.
Always carry out the respective measurement on the film that is closest to the thickness
specified by the coating thickness gauge.
The set of foils included in the scope of delivery is matched to the device. The set of foils may
show slight deviations from the foil thicknesses required by the test instrument during base
calibration. These can be neglected during the base calibration.
7.8.2
Offset calibration
For calibration of the measured values, prepare a calibration standard and the calibration foils.
Navigate to the menu option "offset calibration" as 7.3in chapters 7.2 and 7.3and open it.
Place the calibration foil on the calibration standard that most closely matches the coating
thickness on the object to be measured.
Place the meter on the film in the same way as for a measurement. The gauge will perform a few
measurements. Correct the displayed value with the keys
"①
Up" or
"②
Down" and confirm the
setting with the
"⑤
OK" key.
