The deviations of magnetic compass are to be measured by bearings of objects. However, in case of being unable to bear the objects, a compass is often adjusted by a deflector which measures the ship's magnetic fields. After the adjustment of the compass by the deflector, the residual deviations must be measured at least on eight principal points of the compass. Our previous report presented the formulae with which we can calculate the residual deviations using the readings of the deflector in case of normal deflections on the cardinal points of compass course. In this paper we report the experimental asertainment on the formulae, giving the better accuracy on the calculated residual deviations.
