Abstract: A load cell scale includes a memory for storing span data, a weight data generating circuit for generating weight data corresponding to load weight, and a data processing unit for generating weighing data on the basis of the weight data and span data. The scale further includes first and second keys, and a nonvolatile memory having first and second memory areas. The data processing unit responds to the operation of the first key to store, as zero-point data, the weight data from the weight data generating circuit, into the first memory area of the nonvolatile memory. The data processing unit further responds to the operation of the second key to store, into the second memory area of the nonvolatile memory, the difference between the zero-point data and the weight data from the weight data generating circuit. The difference data is used as span data.

Abstract: Means for supporting an article to be weighed, a low range load cell having a high accuracy weighing range and including means for outputting a first signal in response to a weight on the supporting means and a high range load cell having a high load weighing range which is higher than the high accuracy weighing range, the high range load cell including means for outputting a second signal in response to a weight on the supporting means, are provided. Means are also provided for receiving the first and second signals and for outputting a weight signal as a function of one of the first and second signals, the means for receiving including means for outputting the weight signal as a function of the first signal for any weight within the weighing range of the low range load cell, whereby high accuracy weighing is achieved.

Abstract: A multi-range load cell scale includes heavy- and light-range load cells. For the load weight below a predetermined value, the scale displays the weight data based on the output signal from the light-range load cell. For the load weight above a predetermined value, the scale displays the weight data based on the output signal from the heavy-range load cell. As for change of the load cell from light-range to heavy-range, when it is detected that the weight data WH based on the output signal from the heavy-range weighing load cell is smaller than the weight data WL based on the output signal from the light-range weighing load cell, weight data equal to the weight data WL at the switching point is displayed, in place of the weight data WH.

Abstract: An improvement in a multi-range load cell weighing instrument of the type which has a plurality of load cells including a high weighing load cell positioned adjacent a base and a low weighing load cell positioned adjacent a tray. In the improved weighing instrument according to the invention, the load cells are located such that the center lines along the length thereof substantially coincide with the center line of the tray. Accordingly, if a partial load condition is entered wherein a load is put aside relative to the tray, a force acting to twist the load cells is weakened, resulting in reduction of the frequency of causing flickering of indication.
