I'm trying to measure the output current of a sensor. It is between 4mA and 20mA.
I'm using the NI cDAQ-9171 with the NI 9218 Unit and an additional shunt resistor, NI 9983F (for +- 20mA current measurement):
In the "Start Task" vi does an error occur:
Error -200077 at DAQmx Start Task.vi: 7220001
Property: AI.MaxRequested Value: 20,0e-3Value must be bigger than: -6,644518e-3Value must be smaller than: 6,644518e-3
I tried several examples made by NI or other users but nothing worked!
My current measurement vi.
Thank you in advance!

which driver you are using with DAQmx 16.1 and newer this should not happen, with an older driver the worlkaround is to configure the adapter to NI 9983D.
Thank you, I updated DAQmx and it works!
