2.8 One point calibration
If the device is calibrated to standard measures, for example, carbon steel 35, the
readings on products made of similar steels, with the same heat treatment - will not differ
much. But the values of the hardness of alloy steels and other alloys, which have a completely
different chemical composition compared to standard measures - will differ significantly.
One point calibration is designed to adjust the standard calibration scale of a specific
material for a similar material (chemical composition; mechanical properties).
The accuracy of the new scale from the specific measure to which the calibration was
performed is 15-20%.
To perform one point calibration in the tab "Calibration" (Fig. 2.46) use the buttons
to select the item "One point" and press the button .

To access the calibration, you will be prompted to enter the user password (Fig. 2.47).
Use the buttons to enter the user
password and press .
In the window that opens (Fig. 2.48), use the buttons to select an
existing calibration, Standard or Custom, and press .
