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.
Reset the piston. The piston, which is located on the back of the caliper, is 3 to 4 inches (76.2 to 102 mm) long and changes position as the brake pad wears. Put a piece of wood on top of the piston, place a C-clamp over the wood and the piston, and tighten the clamp until the piston is even with the caliper.
