Measuring apparatus
专利汇可以提供Measuring apparatus专利检索，专利查询，专利分析的服务。并且PURPOSE: To make it possible to correct the drift component all the time, by refreshing an offset voltage at an offset-voltage measuring mode, and correcting the drift component, which is superimposed on a weight-value signal at a measuring mode by the offset voltage.
CONSTITUTION: At the initial state, a switching part 2 is made to be a measuring mode, and the output value W
x of an A/D converter 5 is compared with the output value W
oo when a power source is turned ON. When the result is within a specified range, a load is not mounted, and the output value Wo is memorized and updated. Zero is displayed on a display device 7. When the load is mounted, a counted value W corresponding to a net weight Wg is computed. The number of samplings is counted up. Then the weight Wg is displayed on the display device 7. The switching part 2 is made to be an offset-voltage measuring mode, and the output Z of the converter when an input to an amplifier 3 is grounded is memorized as an offset value. The difference between the offset value and the correcting output Z' at the previous time is computed. The counted number W corresponding to the weight Wg is computed by the value obtained by adding the output value Wo.
