Figure 9-35 Characteristic Curve of a 20-mA Input (Example 1)
In this example, the measured value 0 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
Resolu-
tion
=
0.1
.

Figure 9-36 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).
