I am trying to measure the frequency a 0-14V pulsed output from a turbine flow meter and keep getting the 200284 Error. I am using the cDAQ 9178 chasis and a 9401 digital card and taking the signal in through the bnc connections on the chasis. I have tried the low freqency, high freqency and large frequency range options. I have also tried several different sample sizes from 1 up to 10M with no luck.
