Channel Type for Analog Inputs 1–2
The selection voltage (0 = Default) or current (1) is required due to the different reference values for current and voltage.

Corresponding bit set in the range of 4 to 5 and 0 to 1 means channel selection current 4...20 mA.
The measuring range 4...20 mA is calculated from the value of the 0...20 mA range (value–0x1999) * 1.25.
4 mA correspond to 0x0000 and 20 mA correspond to 0x7fff.
Due to the increased spreading, the number of unavailable codes is increased.
