value signal (in mA) on the display, you wish to receive the amount of water pumped in m
then set a value for par. ID1033 to correspond to the minimum signal level (0/4 mA) and another
value for par. ID1034 to correspond to the maximum signal level (20 mA). The number of decimals
needed can be set with par. ID1035 and the unit (m
signal is then scaled between the set min and max values and displayed in the selected unit.
