The slide caliper is a measuring instrument with a scale and a cursor that drift into it. It was designed to take external linear dimensions, by contact between two opposing sides. With less accuracy, it also measures internal dimensions, depths, bumps, among other.
The scale of this simulator is graduated in inch and it´s divided into fractions. The vernier scale divides the 1/16in by eight, marking the 1/128in.
