AIO Input Values change when using other ports
Posted: 10 Jul 2019, 23:52
Currently I am using 7 ports on the AIO (28,27,23,6,5,2, and 1) which correspond to Inputs and Outputs 1 and 2. The AIO is plugged into the Connect. I am trying to read output voltages from a mass flow meter and a pressure transducer simultaneously. I am supplying 10 V to both devices, but the input range for the pressure transducer is 0-5 V whereas the mass flow meter is 0-10 V. Plugged in separately, they produce the correct values (measured and verified by a multimeter). However, when plugged in at the same time, the voltage values from the pressure transducer (InputValue_1) go way higher. The actual voltage measured from the transducer with a multimeter do not change. The mass flow meter does not seem to have this issue.
I have tried using different the input/output terminals and a different AIO, but the problem persists.
Any help is appreciated!
