2. eZ-TOMAS: Tach Configuration and Discussion
Select Analysis Frequency Based on ~70 samples per revolution at max. machine speed (CPS).
For example, 3600 RPM = 60 CPS 60 CPS * 70 samples / revolution = 4200 samples per second.
Recommend Analysis Frequency = 2000 Hz. (sample rate would be 5120 samples per second … * Fmax)

3. eZ-TOMAS: Tach Configuration and Discussion
