Pull out the black lid (wrap in a paper towel and wring it out hard). Reattach the lid on the roller and adjust the length, so that the bumps on both sides stand on the ruler. Only put the lid on the one side into the groove. Press the lid on the other side into the groove. The ruler returned to normal. Align the center of the protractor on the edge of the ruler with the vertex of the surveying foot, and at the same time, coincide the scale of the protractor with the datum line, then various angles can be measured on the edge of the ruler. Insert the pen into the small hole at the ruler end to make the center of the circle, insert another pen into another hole and rotate the ruler body 360°to draw a circle. If the radius between the 2 holes is different or the rotation ruler body is different, different circles or arcs can be obtained. Press your hand on the ruler body, draw a horizontal line along the edge of the ruler, and then move the ruler up and down to draw a parallel line. Insert the pen into the small hole on the edge of the ruler, slide the ruler up and down to draw a vertical parallel line. The distance between the vertical lines can be measured directly.
