1. Press < > to select, user will see the table as in Figure 2.29. The device, while measuring,
receives nominal codes. The purpose of calibration is to find the correlation between the code
value and the hardness value (to create the function of dependence).
Figure 2.29 - Calibration table
2. To start the calibration, enter the real hardness values of the samples by pressing the key
< >. Using navigation keys < > and < > to set up the real hardness values,
push < > key to enter the next value (Figure 2.30).

3. Press the key < > one more time to set the first value, than the key < > to edit
harrdness value for the next samples.
4. Then move the cursor to the hardness value according to the sample, and make at least five
measurements (Figure 2.31). Make sure that the value of X (the current code value) does not
deviate more than 3%.
