DMP30 / DMP40 Calibration
9.4.1 Calibration step Zero – Procedure
Measure on the uncoated reference piece.
Required material
 Base material FE: ferromagnetic material = FE = ferrous reference piece from
customer's own production, wit hout the coating to be measured; NF/FE dis-
play screen
 Base material NF: non-ferromagnetic, electrically conductive material = NF =
non-ferrous, electrically conductive reference piece from customer's own pro-
duction, without the coating to be measured; NC/NF display screen
To perform the zero calibration step Zero
1. Perform 5 to 10 measurements on the uncoated reference piece.
The display screens should be considered only as examples, the gauge default modes are required here
for the measured reading acquisition.
Repeat Steps A to C for the subsequent measurements on the uncoated refer-
ence piece.
2. Finish the calibration step Zero: OK.
3. What would you like to do?
► Finish the calibration: 1 x
The measuring system is now calibrated to the base material and the part
geometry (= Zero = zero point), the calibration is finished, the calibration menu
with the calibration list appears in the display
► Continue the calibration with calibration standard(s): continue with "Calibration
step Std – procedure", 61
