ABSTRACT:
The indicating pointer of a gauge is rotatably and frictionally connected to a hub which is attached to the shaft from a meter movement for calibration of the pointer relative to the graduation indicia of the gauge, without removal and replacement of the pointer or hub from the shaft. The hub may include a gap within which the pointer is nestable and has limited movement.
