6.9.37 3Fh: 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, setpoint and the differential value if applicable are
calculated by means of the following formula (for position value):
Display value = position value x calculation factor

4-Display factor
9 different calculation factors can be set (see Table 17). The number of decimal places is
selected via parameter 0Ah: Decimal places.
