I'm using a NI 9401 to measure two counter flow meters, which operate anywhere from 2kHz to 20kHz. I'm using Large Range, but would like to use just 1 NI 9401. My understanding is ctr 0 is paired with ctr 1, and ctr 2 paired with ctr 3? Well anyways the error is that the resource is reserved when starting the task. Is running two counters of this type possible on a NI 9401?
Thanks
