Measuring other material
If you do not wish to carry out measurements on low
or non-alloyed steels but on high alloyed steels or ma-
terials as nonferrous metals, then you must adjust the
MIC 10 to the required material.
For calibration you will need a test piece made of the
same material having a known hardness. You deter-
mine the calibration value which you will need with fur-
ther measurements on this material.
The calibration value is an additional value that makes
a subsequent change of the calibration setting easier.
As the calibration value has no physical relation, it has
no designation either.
Due to the fact that you can directly enter this calibra-
tion value you only need to carry out the calibration
once for a certain material.
–
Carry out a measurement set of about 5 single
measurements on your test meterial (corresponding
to the above described measurement on low-alloy
steel).

Press
M
in order to go to the Set level and then se-
lect the function Calibration ( Cal ):
0
Note:
With the DL version (if the Data Logger is active) the
measurement set is stored after pressing
M
. After that
the above display appears.
The active average value reading of your measure-
ment will be displayed.
This value does not correspond to the known, real
hardness value because you have not calibrated the
instrument.
