6.3.7.4 Display Scaling
The display values can be changed by the parameters Gain and Offset.
Corrected value Display value * Display gain - Display offset
You can, for example, add a constant value (offset displacement) or influence the slope
of a characteristic by a gain.
Entry occurs via Main menu > Edit program > Enter offset for display or
Enter gain for display.

The function Display scaling is not available in the Multi-segment measure-
ment program.
Entry of a gain should occur before any mastering or zero-setting, whereas the offset can
be modified after mastering or zero-setting.
To displace the display value add the desired displacement to the displayed displace-
ment and enter the new value at Display offset.
In addition a two-point calibration can be carried out. For the two-point calibration it is
best to use two reference pieces which correspond to the smallest and largest expected
measurements.

The menu points Enter offset and Enter gain are not available in the
Multi-segment measurement program.
The settings Offset and Gain for the display or the analog output have no effect on the
digital value.
