<P>PROBLEM TO BE SOLVED: To provide an electronic force balance which indicates the remaining time to be needed for the work for calibrating sensitivity, from the current point of time to the finish of the work, while a sensitivity calibrating part executes the work. Ž<P>SOLUTION: The electronic force balance 1 includes a weight indication control part 51 which makes an indicating part 60 indicate a weighed value, using a weight detected by a load detecting part 10 and a sensitivity calibration value for calibrating the sensitivity of the load detecting part 10, and the sensitivity calibrating part 53 which calculates and updates the sensitivity calibration value by using a built-in weight 11. The balance includes a storage part 40 which stores a required time needed for the sensitivity calibrating part 53 to calibrate the sensitivity. The sensitivity calibrating part 53 makes the indicating part 60 indicate the required time on the occasion of starting calibration of the sensitivity, and carries out indication of the remaining time to be needed from the current point of time to the finish of calibration of the sensitivity, while calibrating the sensitivity.
