Position the Tool against the Work and Read the Setting. Place the legs of the adjustable tool against the work angle and read the setting for the miter saw, as indicated by the red arrow. The angle is already converted to the correct setting--in this demo, 38 degrees.
(2) Taking the depth measurements: There is a depth bar which is especially used for depth measurement on the digital caliper. Step1: Move the slider of the digital caliper and adjust the depth bar perpendicular to both the hard, flat plane and the internal side of the item.
The jaws of the caliper indicate the formal value of minute of angle (MOA) at 100 yards, 1.0471996 inches, allowing for vagaries of operator interpolation and mechanical tolerances. The ruler shows 1 inch, the commonly accepted value of MOA at 100 yards. The MOA is a useful tool for shooters because it varies in direct proportion to distance. Our nominal inch at 100 yards is a half-inch at 50 yards, 2 inches at 200 yards, 3 inches at 300 yards, and so on.
