Hi,
Hoping that someone can help me.
I have a very strange issue, I have a cDAQ with NI9208, reading multiple 4-20mA pressure transducers fine but does not read 4-20mA signal from the flowmeter(flowmeter has a digital display giving 4-20mA output. (https://flomecmeters.com/downloads/manuals/rt12-owners-manual.pdf))
We have broken into the circuit and with a fluke loop simulator read from the flowmeter, which gives expected output, and using the fluke as a source the cDAQ reads correctly.
When the flowmeter is connected to the NI 9208 it reads about 0.5mA.
We have tried it on a different channel and still get the same issue.

How is the NI 9208 connected ? According Figure 4 of the user manual ?
