The operation unit 34 is provided with an increase key 44 and a decrease key 46 for increasing and decreasing the preset tare value. When the increase key 44 and the decrease key 46 are operated during measuring operation, the preset tare value is changed and automatically displayed in a display panel 32 of the display unit 14 while being stored in the memory 30. |
