Abstract

This paper mainly deals with a novel magneto-optical apparatus with a comparator for the measurement of large direct current. The measuring principle, the probe structure, as well as the experimental data are presented in detail with additional analysis of the apparatus's mathematic model. A long-running test shows that the apparatus, with its measuring range from 6000 angstroms to 16,000 angstroms and its measuring error less than 0.5%, possesses a fine temperature characteristic and long-period performance stability.
