data are reset to zero. Measuring can start again.
13. Calibrating the measuring device
•
Press and hold the confirmation button
(4) to switch to the desired calibration mode (zero
calibration
or two-point calibration
).
• The calibration mode is set as outlined above in section ‘e) Setting calibration mode’ in the
section ‘Menu settings’. Zero calibration and two-point calibration are available.

Carrying out zero calibration
• If you have selected zero calibration
, use an uncoated calibration disc for calibration.
•
If the following figure is shown on the LC display (2), place the sensor (8) directly on the
uncoated calibration disc. Wait for approx. 2 seconds before you lift the measuring device
off again.

Carrying out two-point calibration
• If you have selected two-point calibration
, use an uncoated calibration disc and place
the non-metallic layer thickness standard (of known thickness) over it.
• If the following image is shown on the LC display (2), place the sensor (8) directly on the
calibration disc with the standard layer thickness plate. Wait for approx. 2 seconds before
you lift the measuring device off again.
