Measurement input

Symbol Notes
C111 Transducer/probe (measurement input)
C112 Unit of measurement (°C/°F)/decimal places in display
SCL Start/end value of value range
for standard signals and resistance transmitter
Example: 0—20 mA
SCH
OFFS 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
temperature deviation of 1°C).
Examples:
measured value
294.7
295.3
dF Filter time constant (damping), for adapting the digital input filter (0sec = filter off).
The value range of

- 0.3 295.0
dF
is 0.0 — 100.0sec; factory setting: 0.6sec.
- 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)
