On transducers with standard signal and on
resistance potentiometers, a display value is
assigned to the physical signal (scaling).

Example: 0—20mA

־ 0—1500°C.

The range of the physical signal can be 20 %
wider or narrower without generating an out-of-
range signal.

With a standard signal and customised
linearization, the display range coincides with
the linearization range (range of the x values).
For the above example this means:
Start x = 0, End x = 20, in order that the display
range goes from 0 to 1500 °C.
If the range of the x values is smaller, the dis-
play range is reduced accordingly.

To adjust the digital input filter
(time in seconds; 0.0 sec = filter off).
63% of the alterations are acquired after 2x
filter time constant (2nd order filter) at a filter
time step change.
When the filter time constant is large:
- high damping of interference signals
- slow reaction of the process value display

to process value changes

- low limit frequency (low-pass filter)
