The measured value correction (offset) is
used to correct a measured value by a
certain amount upward or downward.
Examples:
Measured valueOffset Displayed value
294.7 +0.3 295.0
295.3 - 0.3 295.0
Special case: "2-wire circuit".
If the input is connected to a RTD
temperature probe in 2-wire circuit, then
the lead resistance is set in ohms here.

On transducers with standard signal, 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 overrange/underrange signal.

Digital filter

100.0
To adapt the digital input filter (time in
seconds; 0s = filter off).
63% of the alterations are acquired after 2x
filter time constant (2nd order filter) at a
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)
CAUTION!
Measured value offset: The controller uses the corrected value
for calculation (= displayed value). This value does not comply
with the value measured at the measuring point.
Incorrect use can cause inadmissible control values.
Only carry out a measured value offset within the admissible
range.
