Abstract
An apparatus includes a platform that is supported by a first set of load cells. Output from these load cells may be adversely influenced by factors such as temperature, humidity, aging, and so forth. The device includes a second set of load cells that are unloaded, that is they do not support the platform. Output from the first set of load cells is digitized to produce first digital data while output from the second set of load cells is digitized to produce second digital data. The first digital data and the second digital data are processed to produce compensated data. For example, values of the second digital data may be subtracted from values of the first digital data to produce the compensated data. In other implementations, other processing may be used. The resulting compensated data may be used to provide highly accurate weight data about the platform.
