I need to measure RPM between 200 - 1500 RPM (3 - 25 Hz) I've got the example code "Frequency Measurment.vi" to work. But when the result is in Hz, I must multiply by 60 to get the result in RPM, which means that the result is rounded to the nearest 60th What can I do to get a more accurate result.

I spoke with Tommy about this and the solution to the problem was to follow this KB:
Measuring Low Frequencies with LabVIEW and FieldPoint Using [c]FP-CTR-500/502
