Abstract
A method for validating a workpiece measurement in a hand-held spatial dimension measurement metrology tool comprises vibrating a portion of the metrology hand tool using the vibration excitation element; sensing a vibration signature using the vibration sensor configuration; identifying a valid contact state between the metrology hand tool and the workpiece based on a vibration signature criterion; identifying a valid seating state based on a measurement stability criterion applied to a set of dimensional measurements of the metrology hand tool; and indicating that a dimensional measurement is valid for a dimensional measurement that is obtained when the valid contact state and the valid seating state occur simultaneously.
