Defines the minimum %-value that corresponds to minimum
mA/(V) signal for analog input AI1. When used as a
reference, the value corresponds to the reference minimum
setting.

Example: If the minimum value for analog input is 4 mA, the
percentage value for 0...20 mA range is:
(4 mA / 20 mA) · 100% = 20%
