ABSTRACT:
A force measuring device, such as a weighing device, having device for automatically compensating for temperature-induced zero and span deviations. The device includes force and temperature sensors for producing force and temperature indicative signals, respectively. Device for processing processes these force and temperature signals at various temperatures in no-load and reference-load conditions by regressive analysis in order to obtain and store in memory equations representing the zero and span deviations with temperature. During use of the force measuring device for measurement, the device uses the stored equations to calculate the zero and span deviations from the current temperature to correct the force indicative signal.
