Title: Weigher
Inventor: KINOSHITA MASAFUMI
IPC: G01D7/00
Filed: 1986-08-01
Abstract: PURPOSE:To weigh even a lightweight body speedily by controlling a display speed by using weight difference data and weight variation rate data computed from weight data from a weighing part. CONSTITUTION:The weighing part 12 weighs an object placed on a weighing pan 11 and outputs weight data at a constant period. An arithmetic part 13 detects the weight difference of the weight data from the weighing part 12 and also detects the variation rate of the weight data, thereby outputting detection data to a display control part 14. Further, the display control part 14 controls the display speed with the detection data from the arithmetic part 13 and outputs and displays the weight data on a display part 15. Then when a lightweight body is weighed, the weight variation rate data can be made large even when the weight difference data is small, so the display speed is controlled by using the weight difference and weight variation rate. Consequently, a flicker of the display due to the influence of wind and vibrations almost at 0g where no measurement is taken is eliminated and the light-weight body is measured stably.
