| Abstract: | This frequency meter is controlled by a microcontorller 8031,and the measuring error is corrected by a way of two sequent table. Its accuracy can be corrected by a higher accuracy standard digital multimeter at any time,All these factors can ensure the measuring accuracy and simplicify the circuits and make the correction easy. This method can he also used into any other digital multimeter or intelligencing instruments accuracy. |
