For values below the measured value 0, the output current decreases linearly to a minimum of 3.8 mA
(-1.25 % of the measurement range). Further underflows cannot be evaluated (output 3.8 mA). If the
span is exceeded, 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).

For values below the measured value 0, the output current decreases linearly to a minimum of
-12.5 mA (approx. -1.6 % of the measurement range). Further underflows cannot be evaluated (output
