Abstract
A method of calibrating a scale which enforces exercise requirements. The method includes causing an interface to provide a first indication to place weight on the scale by control circuitry of the scale, receiving weight signals from a load cell by the control circuitry, causing the interface to provide a second indication that exercising has begun and of the level of weight applied by the control circuitry, determining that a minimum recommended calibration weight has been placed on the scale by the control circuitry, and causing an interface to provide a third indication that the minimum recommended calibration weight has been placed on the scale by the control circuitry.
Claims19
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.
A method of exercising a scale as part of calibration of the scale upon installation for commercial purpose, the method comprising:
- sensing activation of a scale calibration switch by a controller;
- initiating a calibration process by the controller with an exercise process;
- providing an indication to an operator to load the scale with a recommended calibration weight, where the recommended calibration weight is a maximum weight the scale is designed to read;
- utilizing the controller to monitor weight signals from a load cell as the scale is loaded;
- determining by the controller when the recommended calibration weight is reached by analyzing the weight signals;
- and
- providing an indication to the operator that the recommended calibration weight has been reached.

- (g) removing all weight placed on the scale;
- and
- (h) repeating steps (c) through (g) a predetermined number of times.
