Calibration
7.1 Calibration - When necessary?
• When you have a new measuring application, the influencing factors
must be recorded in order to compensate for them when measuring.
Recalibration - When necessary?
• When the correctness of the measurement is not assured
7.2 Selecting the appropriate calibration method
A measurement can only be performed if a calibration using the appropriate
calibration method is assigned to the batch in the gage. A calibration method
is assigned to each batch type. Selection of the batch type and the associated
calibration method is based on the requirements of the guideline/standard or
the accuracy of measurement needed.
You can find the associated calibration and calibration method in the batch
information for the particular batch.

A calibration method guides you through the calibration procedure step by
step. The following calibration methods are available in the gage:
Calibration methods
• Flexibel (Calibration steps Zero and up to two time Foil)
The same routine as Zero + 2 Foils, but in this routine you can skip indi-
vidual calibration steps
• Zero (zero point, calibration step Zero)
This is the simplest type of calibration and is used to adjust the gage to
a reference point, the base material, also called Zero (zero point). The
measurement is taken on a reference part that has the same material and
shape as the uncoated sample to be tested. It utilizes only the sample's
base material (magnetizable or non-magnetizable, depending on the test
method used), i.e. without the coating material to be measured.
• Zero + 1 Foil (calibration steps Zero and one time Foil)
A calibration with a calibration foil yields the best measurement accuracy
in a narrow coating thickness range around the stated film thickness. The
