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
.
i
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.

Display gain: 0.99800
Display offset: +0,0110 mm
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.
