Universal angle rule verification procedure
1 Scope
This procedure applies to cursors and gauges with scale values of 2' and 5', measuring ranges from 0° to 320° and 0° to 360°.
The first test of the angle ruler, the subsequent test and the test in use.

3 Overview
The universal angle ruler is a universal angle measuring instrument that reads the angle separated by the relative movement of the two measuring faces.
The main structural types are 1 type (Fig. 1) and 2 type (Fig. 2). The vernier universal angle ruler and the table universal angle
The ruler (Figure 3). The basic parameters and dimensions of the universal angle rule are listed in Table 1.
