PURPOSE:To improve operation efficiency by turning off LEDs of respective measuring instruments in order automatically when detecting articles being removed from the measuring instruments. CONSTITUTION:Circuit components such as an AD converter and an interface of the respective measuring instruments are arranged on a measuring instrument substrate (a) and every three of the measuring instruments #2-#10 are installed together in housing (g) while only one measuring instrument #1 is put in a housing as a main scale (c). Then the LEDs (d) which indicate the participation of the measuring instruments in combination are provided on both sides of the measuring instruments. Weight data obtained by the respective measuring instruments are sent out to a power source part (f) and a CPU monitors the weight data of the respective measuring instruments by polling. Here, when the holding start of the LEDs is set manually or automatically, the removal of all articles from a measurement disk is detected automatically, the holding is reset automatically, and the LEDs are turned off, so that a next combinational measurement is taken.
