PURPOSE:To measure net weight with a proper minimum scale unit by setting two kinds of minimum scale unit and changing the scale unit automatically on the basis of net weight as a boundary according to the specified weight. CONSTITUTION:The minimum scale units of 1g and 2g are provided and weighing of 0-3kg on the 1g unit and 0-6kg on the 2g unit is carried out. When the power source is turned on, a weighing means 3 measures the weight including tare and a tare-free weight discriminating means 4 measures up to 3kg net weight on the 1g unit to display the weight on the 1st 1g unit 1. A minimum scale unit switching means 5 changes the minimum scale to the 2g unit up to 6kg net weight to display the weight on the 2nd 2g unit 2. Therefore, the net weight is obtained on a proper minimum scale unit regardless of the tare. |
