All channels share the same original, factory-set, configuration: the scale factor is 16.56 °C/mA.
This setting results in the 0 °C offset to be at 6.41 mA, the minimum 4 mA scale limit to be at -40 °C and
the maximum 20 mA scale limit to be at 225 °C.
For example, as for channel 1 in the Analog Output screen shoots below; if the loop reads 7.69 mA, the
corresponding temperature for that channel is then 21.19 °C:
(7.69 mA
–
6.41mA) × 16.56 °C/mA = 21.19 °C.
