PROBLEM TO BE SOLVED: To provide an electronic force balance/electronic weighing instrument capable of performing data communication without requiring cable connection to external equipment. SOLUTION: This electronic force balance/electronic weighing instrument is equipped with a radio communication device 5 for modulating/demodulating communication data, a frequency switching device 4 for switching a radio communication frequency, a storage device 3 for registering/storing the communication frequencies of a plurality of radio communication apparatuses, a frequency switching means for checking the communication data and selecting and switching automatically the communication frequency, and a communication data conversion means for converting a variable into radio communication data. Hereby, the communication data are checked in each transmission, and switched into the radio communication frequency of a counter communication address and transmitted wirelessly.
