| description | A method and apparatus for carrying out auto-calibration of one or more piezoelectric elements in a force transducer assembly of a vehicle wheel balancing system. Output electrical signals from the piezoelectric transducers in response to application of a known imbalance force are measured and recorded. Subsequently, during an auto-calibration procedure, a known input signal is selectively applied to at least one piezoelectric element in the force transducer assembly, and at least one output electrical signal is received from the force transducer assembly. The obtained auto-calibration output signals are evaluated with respect to the output signals obtained from a previous auto-calibration, and compensation values are derived there from for application to subsequent output signals obtained during imbalance measurements. |
