Abstract

See full text

Real-time clock circuitry integrated in an electronic torque tool facilitates time-stamping of torque data acquired by the electronic torque tool. The time stamped torque data may be displayed on a display integrated in the electronic torque tool or may be communicated to an external device. The real-time clock circuitry may be adjusted based on information received from an external device or may be manually input to a keypad of the electronic torque tool. A calibration timer integrated in the electronic torque tool monitors time between calibrations of the tool and notifies a user upon expiration of a calibration interval. A secondary power source is coupled to the real-time clock circuitry to maintain power to the real-time clock circuitry during battery replacement.
