Krautkramer DM4E - 5.3 Thickness measurement

5-10 Issue 05, 01/01 Krautkramer DM4E / DM4 / DM4 DL
Operation Thickness measurement
5.3 Thickness measurement
Standard measurement: THK mode
The following description of the thickness measure-
ment applies to test objects whose surface tempera-
ture corresponds to the ambient temperature. If you
require to carry out measurements on hot surfaces
refer to Chapter 11.1 Application information.
If you want to carry out measurements through coat-
ings, use the operating mode DUAL MULTI (please
refer to page 5-16).
Operation:
Make certain that the instrument is switched on and is
calibrated to the selected probe and the material to be
measured (refer to Chapter 5.2 Calibrating the instru-
ment).
If you require to work with alarm limits (only DM4 and
DM4 DL) read the procedure in Chapter 5.4, Page
5-13.
Make certain that the surface of the material is free of
dirt, remains of paint etc. and then apply a thin layer of
couplant onto the surface of the material.
– Select the THK mode (if necessary press m).
– Place the probe carefully but firmly onto the surface
of the material. Apply a constant pressure in order
to obtain a stable measurement value.
The coupling symbol p appears when there is suffi-
cient coupling. At the same time the thickness reading
is displayed, e.g.:
– You can now couple the probe.
The coupling symbol blanks. The displayed measure-
ment value is retained.
