摘要
介绍了一种利用单片机能对感应式单相电度表制动磁钢进行退磁的控制仪的研制，该退磁仪可与电度表校验台配套，实现对电度表误差的自动预校，特别适用于固定式磁钢结构电度表的满载预校，亦可用于可调节式磁钢结构电度表的满载预校裕度的调节。
：The article introduced the development of demagnetisation instrument of breaking magnet based on 8031 microcomputer． The instrument can implement autmatic precalibration in single－phase watt－hour meter by means of the demagnetization processing of breaking magnet．This instrument especially adapts to demagnetisation processing of breaking magnet fixedly in watt－hour meter． Also the instrument can be applied to adjustment of fully loaded precalibraton of watt－hour meter expecially to which breaking magnet emplacement is not fixedly．
