Digital caliper is a measuring instrument (measuring) equipped
with a linear slider that glides on a ruler. It is designed to
take linear measurements of external contact. It can also
measure internal dimensions, depths, among other bumps,
eliminating the need to interpret the reading. An electronic
device increases the distance traveled by the cursor and
presents it in a liquid crystal display. One advantage of this
geometry is the possibility of switching between the measure
presented millesimal-tenth inch and hundredths of a millimeter.
Another advantage is the ability to zero the instrument at any
point in the past to see the difference between the measures
facilitating the inspection of various parts of tolerance
without the need to interpret each one, for example. For
reference, the main scale of the simulator is graduated in
decimal inches and millimeters. This instrument, as a rule, can
not replace the micrometer resolution thousandths inch, because
its accuracy (inaccuracy between the actual value sh
