Correction of the actual value
Actual-value correction permits adjusting a measured value upwards or downwards by a
programmable value (offset). For a 2-wire circuit, lead compensation can thus be implemented
in the software (for Pt100 probes, for example, a lead resistance of 0.39
programmable value (offset). For a 2-wire circuit, lead compensation can thus be implemented
in the software (for Pt100 probes, for example, a lead resistance of 0.39
⍀ corresponds to a
temperature deviation of 1°C).

dF
Filter time constant (damping), for adapting the digital input filter (0sec = filter off).
The value range of
dF
is 0.0 — 100.0sec; factory setting: 0.6sec.
if
dF
is large:
- high damping of interference signals
- slow reaction of the actual-value display to changes in the actual value
- low limit frequency (2nd order low-pass filter)
- slow reaction of the actual-value display to changes in the actual value
- low limit frequency (2nd order low-pass filter)
