4.5.9 Display Factor
If a display factor>0 is set, all values on the display are indicated in inch.
It should be noted that the transmission values from and to the interface are present in the
metric system (depending on resolution and ADI). The control delivers target, calibration and
offset values as well as loop length and target window metrically as well. Device-internal
position monitoring is metrical. Therefore, the superordinate control can only function in the
metric system. The values for position, target value and the differential value if applicable are
calculated by means of the following formula (for position value):
