Title: Electronic force balance having improved in noise resistance
Inventor: NAGANE YOSHIKAZU
IPC: G01G23/37
Filed: 2000-05-16
Abstract: PROBLEM TO BE SOLVED: To permit automatic reset of the function of an electronic force balance, or to facilitate restarting, by evacuating necessary data simultaneously when an electromagnetic noise is generated in the electronic force balance. SOLUTION: A logic voltage LV of a power source applied on a central processing part 3 or the like is always monitored. When the logic voltage LV is lowered to a value determined beforehand by generation of the electromagnetic noise, various kinds of data are evacuated simultaneously to a nonvolatile memory part 8, and the function of the electronic force balance is suspended temporarily, in order to prevent malfunction of the electronic force balance caused by the noise. When the noise disappears and reuse of the electronic force balance becomes possible and the evacuated data are enough, automatic reset is executed into the original mode. When the evacuation data are not enough, lost set values or the like are inputted again, and the device is restarted.
