Lesson 1/Learning Event 2
Additional micrometer reading exercises later in this lesson will assist you
in understanding how to read micrometers.
ADJUSTING THE MICROMETER CALIPER TO WORK
Figure 11, Part A, shows the proper way to hold a micrometer caliper in
checking a small part. Hold the part in one hand. Hold the micrometer in
the other hand so that the thimble rests between the thumb and forefinger.
The third finger is then in a position to hold the frame against the palm of
the hand. When the frame is supported this way it is easy to guide the work
over the anvil. The thumb and forefinger are thus in position to turn the
thimble either directly or through the ratchet and bring the spindle over
against the work.
