.5 precission

[bndbryant]

I am a LabView newbie. I am using a hall effect sensor to find RPM. I set up my program to read out rev per second and I then multiply it by 60 to get the RPM. I am only getting returns of rps in incruments of 0.5 (I.E. 0.5 rps, 1 rps, 1.5 rps, 2.5 rps, ect......). What can I do to get more precision? Thanks.

Presumably your sensor resolution in rps is low. Maybe you could show us what you thus far to help rule out any other possible causes.

Hi Bryant,

how many pulses per revolution does your sensor count?

Example: With two pulses per rev you will be able to measure rotation speed in steps of 0.5rps (when you take a sample each second) - there are no more pulses to count!

Again: Please provide more details about your sensor AND your program to get reasonable answers!
