To use the Caliper to measure the outside diameter of an object, close the Out-
side Diameter Jaws (2) over the object, making sure that the item rests squarely
on the Jaws. See Figure C, below.
Make note of the value along the Sliding Index Edge (7). Then read the whole
number indicated by the dial arm. Finally, note the numbers of lines after the
whole number. For example, values 1.5, 30 and 3 will read as 1.5", 0.030" and
0.003", which equal 1.533".
