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).
