3 Overview
Needle gauge, three-pin is of a nominal diameter of the measuring cylinder. Set the amount of needle gauge, mostly spaced by a certain size
With the general inspection aperture for the workpiece; standard gauge needles used for instrument calibration. Three needles are usually used in groups, three diameters
The same as a set of three needles, thread diameter for measurement. Needle gauge, three needle-like Figure 1.

4 Metrological characteristics
According gauge needle, three needles purposes, it should be calibrated following metrological characteristics.
--- Roundness;
--- Plain line straightness;
--- Diameter and the diameter variation.
Note. Metrological characteristics related product standards set forth in Appendix A.
