Figure 10-25 Characteristic Curve of a 20-mA Input (Example 1)
In this example, the measured value -20 mA means a temperature of 0 degrees Celsius and the measured
value 20 mA a temperature of 100 degrees Celsius. Thus, Unit = °C and Conversion factor = 100 are
entered. The resolution (decimal place) of the temperature value can be chosen; for a decimal place, select
Resolution = 0.1.

Figure 10-26 Settings for Example 1
If a value smaller than -24 mA or larger than +24 mA is applied to the measuring-transducer input, the meas-
ured value is marked as invalid. If the parameter Range active is activated, the 2 additional parameters
Upper limit and Lower limit appear. Both limiting values indicate the input currents in mA, for which
the value set by the Conversion factor (Upper limit) and the value 0 (Lower limit) of the calcu-
lated measurand are valid (see following figure).
