Abstract
A fluxgate-magnetometer-mounted-theodolite was experimented for observation of
declination and inclination. By initial experience, a newly purchased sensor which is less influenced by the surrounding conductors was introduced. We repeated the measurement for five months with the instrument fixed on a pillar. As a result of comparison with the standard instrument of Kakioka observed on the same days, the difference between the two and the variation were small. Then, synchronous measurement with the two instruments on D- and I-reducible pillars showed good agreement. So, it is confirmed that this instrument has good performance equal to the standard instrument of Kakioka.
