May I know how to figure out the raw data value related with the voltage and resistor that have been chosen. These raw data value will be the input min and max, right?

As stated above the raw data for 0-10v input for the embedded analog input for the ML1400 is 0-4095. 1.88/10=.188 .188*4095=770 9.4/10=.94 .94*4095=3849 So using the "SCP" instruction and assuming the value of your resistor is exactly 470 ohms, then Input min=770 Input Max=3849 Last edited: Feb 23, 2017
