Gauge
The gauge on most measuring instruments is a transducer that converts mechanical or optical measurement into a signal in order to carry out an analysis of the component. Sometimes called the ‘pick up’ or ‘probe.’
Gauge Calibration
This is the measurement of an appropriate calibration standard (ball, flick, prism or 3-line standard) to derive a set of calibration constants. These constants will be used in any calculations to ensure integrity of results.
Gauge Range
This is the linear distance over which the gauge can measure. It should be noted that the specific gauge doesn’t always dictate the range, changing the stylus from one length to another will affect and change the range.
Gauge Resolution
The smallest numerical value that the gauge can resolve a defect.
