AI summary

A method system of reducing operator-induced error in measurements comprises a measurement tool, such as a diameter gage, that is configured to communicate electrical signals representative of measurements to a computing device, which is configured to receive the signals and to determine a value for the measurement without the operator having to interact with the tool to zero the gage, acquire the data or transmit the data.
