HOW TO READ A CALIPER

For instruments 3202 Series:
• Each bar graduation (6) represents 0.1", numbered in sequence 1, 2,
3, etc. Each tenth graduation represents 1", numbered in sequence 1
(1"), 2 (2"). The dial has its display graduated in 100 parts, each one
representing 0.001 ". Each tenth trace is numbered in sequence 10
(0.01 "), 20 (0.02"), allowing direct reading in a thousandth of inch (a
complete revolution of the dial represents 0.1").
• To take the reading on the instrument, first count how many inches
and inch tenths exist between the zero trace of the bar and the left side
of the slide (zero reference of the slide). Then, look for the graduation
indicated for the dial hand and write down its value in thousandth of
inch. Add the thousandth of inch reading from the dial indicator to the
number from the bar. This is the total reading.
To obtain the reading see the example on fig. 10, adding:
a. ... 0.60" on the bar
b. ... 0.022" on the dial (each revolution represents 0.1")
 0.622" is the reading
