3 Terminology and Definitions.
The terms and definitions established in GB/T 17163-1997 and the following apply to this standard3.1
Inner diameter indicator dial bore gauges
Using a mechanical transmission system、 the linear displacement of the movable measuring head is transformed into the angular displacement of the pointer on a circular dial、 and the dial is used to read
the internal dimension measuring instrument.
3.2
Adjacent error
The specified error * limit between adjacent inspection points on the inner diameter indicator.
3.3
Centering error
In measurement、 the error caused by the deviation of the connecting line between the movable and interchangeable measuring heads of the positioning bridge type inner diameter indicator and the contact point of the calibration ring gauge from the diameter of the calibration ring gauge.
3.4
Operating travel
The inner diameter indicator measuring head is used to measure the movement range.
3.5
Pre compression travel
The inner diameter indicator measures the pre compression amount before the working stroke of the head.
3.6
Length below grip of the lower part of the handle
The distance between the lower ends of the insulated hands and the centerline of the measuring head.
