Setting The Bore Gauges

If plus and minus readings are required, adjust the extension until the "minimum" reading occurs, roughly midway in the range of the dial indicator. Should the full plunger travel be required in one direction, adjust the extension until the indicator registers just at the beginning or end of its travel according to the direction required. Lock the extension securely with the nut. The indicator with its shroud can be adjusted on the body of the gauge if socket-head clamp screw "H" is loosened. Using this adjustment and the rotatable bezel of the indicator, the hands and main dial can be positioned wherever required within the range of movement.
