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 3.8 mA
(-1.25 % of the measurement range). Further decreases cannot be evaluated (output 3.8 mA). If the
value exceeds the end value, the output current increases linearly to a maximum of 20.5 mA (approx.
103 % of the measurement range). Further increases cannot be evaluated (output 20.5 mA).

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.
Values below the start value cannot be evaluated (output 4 mA). Values above the end value cannot
be evaluated either (output 20 mA).
