13 Notes on measurement and calibration

13.1 Influences on measurement accuracy

The accuracy which can be obtained by the instrument is affected - amongst
others - by the following factors:
coating thickness
curvature of the surface
foreign objects
conductivity of the coating
Additional method-specific factors are:
Magnetic-inductive method (DIN EN
ISO 2178)
magnetic qualities and thickness of
the substrate
machining orientation of the sub-
strate
magnetic fields and residual mag-
netism
conductivity of the coating
Instruction Manual LEPTOSKOP 2042
edge effect
roughness of the surface
contact pressure and orienta-
tion/inclination of the probe
Eddy current method (DIN EN ISO
2360)
electric qualities and thickness of the
substrate
temperature effects
intermediate layer
