Patent ID: 7681431

Claim:
A method of calibrating a scale comprising: (a) sensing activation of a scale calibration switch by a controller; (b) initiating a calibration procedure, by the controller causing an interface to provide a first indication to an operator to place weight on the scale; (c) receiving weight signals from a load cell as increasing weight is progressively placed on the scale; (d) upon detection by the controller of the weight signals, causing the interface to provide a second indication that exercising has begun and of the level of weight applied; (e) as the controller detects signals indicating progressively increasing levels of weight, analyzing the weight signals by the controller to determine if a recommended calibration weight approximately equal a maximum weight the scale is designed to read has been placed on the scale; and (f) upon determination by the controller that the recommended calibration weight has been placed on the scale, utilizing the controller to control an interface to provide a third indication that the recommended calibration weight has been placed on the scale.
