The last and most important step is to enter the hardness values of
the calibration test blocks or samples. To begin this process touch
on Calibrate .
Figure 3.26: First calibration point for the user material
To enter the first calibration point for the new user material make N
number of measurements on a calibration test block of a known
hardness value. The N number is set in Group (N) (page 39).
The following two options are displayed on the calibration screen:
N=0 : touch the key to reset the N number of samples in case of
erroneous measurements
Erase : touch the key to erase the last measurement
Single values will be displayed with large numbers and when the N
number of measurements is completed the symbol will appear
showing the average for the N number of measurements. In the line
marked
the hardness value can be edited so that it matches the
value of the calibration test block or sample.
Touch
to accept the first calibration point and two additional
options will be displayed as follows:
