Measuring a range of frequency with Time and Transition Measurements

[Jay_Smasher]

Hey yall,

I'm measuring frequency right now with the Timing and Transitioning Measurements VI.  I'm sampling anywhere between 1 KS/s to 2KS/s and I've noticed it works well for frequencies above 40 Hz (my normal operating range is between 50-500 Hz) but if for some reason it goes down below 10 Hz (which is when I don't need the sensor and I assume it's off), I get errors saying that the signal has not crossed the reference point enough times.  While I could simply turn off the VI's when they aren't being used, I'd like to just have them all in one loop as speed is not an issue as of yet.  I also don't care about data below 10 Hz as I will just assume it is zero.  Any suggestions about how to bypass this error?  Thanks.

Hi Russell,

You would need to convert the Timing and Transition Express VI to a regular VI and then delve into its block diagram to see where the error is being generated. After that it is a simple matter of using Clear Error.VI to ignore the error.
