Abstract
A high precision DC B-H curve tracer is developed which uses microcomputer control. The error caused by the drift of DC amplifiers is automatically corrected and the difference between the starting and finishing points of the curve is automatically corrected to zero. The measuring and plotting interval along the curve can be constant. These are totally processed by the microcomputer.
