Process value input

Symbol Notes
C111 Transducer/probe (process value input)
C112 Unit of process value (°C/°F)/decimal places of display
SCL Start/end value of value range for standard signals
Example: 0—20 mA
SCH
OFFS Process value correction
Using the process value correction, a measured value can be corrected by a programmable
amount upwards or downwards (offset).
Lead compensation can be implemented in software for 2-wire circuit through process value
correction.
Examples:
Measured value
294.7
295.3
dF Filter time constant (damping) to adapt the digital input filter (0sec = filter off)
dF
if high:

Offset Displayed value
+ 0.3 295.0
- 0.3 295.0
- high damping of interference signals
- slow reaction of the process value display to changes in the process value
- low cut-off frequency (2nd order low-pass filter)
