Abstract
A moving coil measuring instrument wherein at least one end of the axis (3) of rotation of the moving coil (1) is supported so as to permit adjustment of that end of the axis (3) in a direction substantially perpendicular to the axis (3), such adjustment correcting for non-ideal operation of the instrument. The adjustment is effected by rotation of a support member (5, 7), defining the one end, rotatably mounted in a frame member (9) of the instrument, the support member (5,7) defining the one end at a location displaced from the axis (31, 37) of rotation of the support member (5, 7).
Claims5
A moving coil measuring instrument comprising:
- a moving coil supported for rotation about an axis defined by a pair of spaced support members mounted on a frame member of the instrument, at least one of said support members being controllably movable relative to said frame member while mounted thereon so as to reposition said one support member relative to said frame member and thereby permit adjustment of the position of one end of said axis defined by said one support member in a direction substantially perpendicular to said axis.
