The dial indicator is supplied with a magnetic base stand. Fitting the dial indicator to the stand provides a motionless and stable means of measuring runout. The solidly constructed base is easily adjustable and has a fine adjustment feature on the boom arm. For added stability, the magnetised base grips solidly to any ferrous metal surface and has a 60kg pull. The magnet can be turned on and off with the switch. The base is V-shaped for positioning on curved or cylindrical surfaces.
