Influencing Variables Taken into Consideration
Corrective Calibration
If the trueness is not met when making measurements on customer refer-
ence parts (customer standards), a Corrective Calibration should be
performed. The Corrective Calibration adjust the measurement system to
the properties of the specimen. The Corrective Calibration not only adjusts
the system to the substrate material but also to 1 coating thickness value
by using so-called calibration foil or standard.
4.2 Calibration - General Notes to Observe
• Care should be taken during the calibration to ensure that the measure-
ment location on the reference part is approximately at the same position
where it will be on the part to be measured (curvature, distance to edge,
hole, offset and step).
• In general, the material properties (permeability) of the specimen will dif-
fer significantly from those taken into account in the factory pre-calibra-
tion. It is, therefore, essential to perform the normalization or corrective
calibration, respectively, using uncoated reference parts (specimens)
from your own production!
Please Note!
Perform the calibration carefully! It determines the accuracy for the subse-
quent measurements. - Measurements can never be more accurate than the
calibration!
