Behaviour of the current output

EN
The linear behaviour outside the measurement range described in the following only results if
temperature values ranging between the minimum value and the maximum value of the selected
sensor correspond to the current values. If this is not the case, the output current jumps to the
minimum or maximum specified value. The Diagnosis window (see section 6.5) shows the
message Above limit or Below limit.
If you select Characteristic inverted, the conversion of start value and end value will be inverted.

At this setting, the start value of the measurement range is converted to 4 mA and the end value
to 20 mA. Intermediate values are converted proportionately.
If the value falls below the start value, the output current decreases linearly to a minimum of 0 mA
(-25 % of the measurement range). Further decreases cannot be evaluated (output 0 mA). If the
value exceeds the end value, the output current increases linearly to a maximum of 22 mA
(approx. 112.5 % of the measurement range). Further increases cannot be evaluated (output
approx. 22 mA).
