Use:
The zero position of the universal angle ruler should be calibrated first. The zero position of the universal angle ruler is installed on both the angle ruler and the ruler. The bottom edge of the angle ruler and the base ruler have no gap contact with the ruler. At this time, the main ruler is aligned with the “0” line of the vernier.
After adjusting the zero position, any angle in the range of 0-320 degrees can be measured by changing the mutual position of base ruler, angle ruler and ruler.
