  • Method and apparatus for reducing magnetometer errors
    Patent number: 4194150
    Abstract: 1. A method of correcting errors in the electrical characteristics of a tl field magnetometer after the magnetometer is tested and said errors are measured and resolved, which comprises correcting the core turnover errors in said total field magnetometer by replacing a pair of cores thereof with a new pair of cores having the same total reductance as the first pair and the difference in reductance of the replaced cores different than the difference in reductance of the cores which are replaced, and subsequently correcting the block misparabolism errors in said magnetometer by adjusting at least one of the cores of the magnetometer to a new angular setting thereof so that the indication of field strength will be within prescribed limits of accuracy.
