PURPOSE:To permit zero-tracked displaying even during compensating of tare by monitoring the data on the count value after correction of tare weight and adding the tare weight gram in a memory to the prescribed weighing data. CONSTITUTION:An operating part 13 interposed between a zero point correcting part 3 and a tare correcting part 6 adds the tare weight written in a memory 7 to the weighing data D2 which is the output of the part 3. A discriminating part 9 monitors weighing data D3 and at every application of an external tare subtration instruction P3, the memories 4 and 7 are refleshed. The memory 4 is also refleshed by the tracking instruction P1 of the part 9. Thus if tare A gram is placed while a zero point correcting value Z and a tare correcting value T are both zero grams, the weighing data D1, D2, D2, D3 are the A gram. The data D3 after the tare correction is maintained at zero grams. |
