Hello everyone,
This is my first attempt to use cRIO and I'm using NI-9381 module with cRIO 9040. I'm trying to read pressure values of a sensor (MIDA-DI-13P) which gives output as 4-20 mA. I established the connections but I read zero value constantly, is there a way to read current value with NI-9381?
Thanks in advance

NI-9381 does not have current input but voltage input channels. To measure current using voltage input, you need a shunt resistor. See Measuring Current with the NI Analog Voltage Input Channels
