Hi,
I want to use a myRIO in order to measure a voltage of a 9v battery and later on measure the voltage accross resistors. However there are values greater than 5v that is why i am using the C port using the differential analog in.
The problem is that when I have nothing connected to the connecting wires (while they are connected to ports) and jiggle the wires, i see the value of the measurement change. Also when I connect the battery i see the measurements going from 0 to 8.77.
Any help is appreciated... I do believe it is a straight forward application.
Regards
