hello, looking for some help/advice...?
i'm currently running a Turbocharger rig with a passive variable reluctance sensor, which is operating from 1v lowest speed to 24v highest speed. however i'm finding the NI-9361 card wont pick up until the probe is 'putting out' over 3v. (read from a PICO scope)
did some digging into the Cards the 9361 indicates it operates 0-24V in a single ended conection (this is what im using)
i dropped a desktop Hz generator onto the input signal to test the cards input range, and i'm finding the card wont read when the voltage is below 2.9v (even in NI MAX)
i'm running the signal into 2 seperate 9361 cards also so i'm certian its not the specific card causing the issue.
has anyone had experiance with this before at all? could anyone advise?
Kindes regards
