Abstract
A method for identifying a principal tooth in a series of teeth extending along at least a portion of a periphery of a rotatable object includes the steps of rotating the rotatable object, setting a counter to a predetermined value, measuring a first tooth in the series of teeth to obtain a first measurement, adding a qualifying value to the measurement to obtain a qualification measurement, measuring a second tooth in the series of teeth to obtain a second measurement, comparing the second measurement to the qualification measurement, and identifying the second tooth as the principal tooth when the second measurement exceeds the qualification measurement.
