Parameters Comment
Value range
(default setting in bold)
9.2.2 Offset Using Offset1, a measured value at the analog input can be
corrected by the value entered over the entire measuring
range. -999.9 to 0.0 to 999.9
9.2.3 Lead wire resis-
tance
Lead wire resistance analog input 1
in two-wire circuit
This value is used to compensate the resistance of the probe
line and depends on the line length.
Enter the ohmic resistance of the probe line here to achieve
the best possible temperature measurement.
0.0 to 30.0 ohm
9.2.4 Filter time Time constant of the digital input filter
2nd order for analog input 1
If the input signal changes suddenly, approx. 26 % of the
change is recorded following a period that corresponds to the
filter time constant dF (2 × dF: approx. 59 %; 5 × dF: approx.
96 %).
Value 0 means: filter switched off
If the filter time is long:
- Interfering signals are better absorbed
- Measured value display responds more slowly to changes
0.0 to 0.6 to 100 sec
9.2.5 Scaling start Here, the user selects which value (i.e. pressure) should be
displayed at 4 mA. -9999 to 0 to 9999
9.2.6 Scaling end Here, the user selects which value (i.e. pressure) should be
displayed at 20 mA. -9999 to100 to 9999
