HOW TO READ A CALIPER
For instruments 3202M Series:
• Each bar graduation (6) represents 1 mm, numbered in sequence 10,
20, 30, etc. Each tenth graduation represents 10 mm, numbered in
sequence 10 (10 mm), 20 (20 mm). The dial has its display graduated
in 100 parts, each one representing 0.02 mm. Each fifth trace is
numbered in sequence .1 (0.1 mm), .2 (0.2 mm), allowing direct
reading two hundredths of a mm (a complete revolution of the dial
represents 2 mm).
• To take the reading on the instrument, first count how many mm 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 .02 mm. Add the .02 mm 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. 12, adding:
a. ... 13.0 mm on the bar
b. ... .66 mm on the dial (each revolution represents 2 mm)
 13.66 mm is the reading
