SECTION 4: DIAL INDICATOR
General Usage Tips
The dial indicator can be used for many
precise measuring tasks. The magnetic
base can be positioned on flat or round
surfaces. Below are some tips to follow
when using the dial indicator and base.
• Turn the magnetic base OFF when
moving the unit to prevent damage to
the current mounting surface, and to
prevent sudden jarring that could damage the internal components of the dial
indicator.
• Make adjustments to the support
assembly only with the base magnetically secured to a steel or iron object.
• Always loosen the lock knobs when
positioning the boom and dial indicator.
Make sure they are tight before making
fine adjustments to the dial indicator.
Adjusting the
Assembly
The support assembly can be adjusted
to provide a longitudinal reach of 21" and
a 360° lateral reach of 111⁄2 ", as shown in
Figure 7. This means the contact point of
the dial indicator can reach virtually any
point within this space.

1. Loosen the lock knob on the support
column enough to allow the boom arm
to pivot, and the lock knob to slide
along the length of both the support
column and the boom.
2. Set the boom height and rotation to the
desired position, and tighten the lock
knob so that it allows the boom to pivot
with slight resistance.
3. Make any adjustments to the boom
angle and tighten the lock knob completely.

Indicator
Setting the Contact
Point
The dial indicator position can be finetuned to provide the optimum measuring
conditions.
To adjust the dial indicator position:
1. Loosen the lock knob on the boom
enough to allow the boom arm to pivot,
and the lock knob to slide along the
length of the boom.
2. Set the dial indicator position along the
boom and tighten the lock knob so that
it allows the dial indicator to rotate with
slight resistance.
3. Loosen the knurled nut with a screwdriver or by hand so that the dial indicator can pivot freely. Set the dial indicator to the desired angle and tighten
both the knurled nut and the lock knob
completely.
4. If the dial indicator is in position but
the measuring angle is still not exact,
the fine-tune adjustment knob may be
turned clockwise or counterclockwise
to change the angle of the boom, as
shown in Figure 8. It can also be
used when setting the contact point, as
shown in Figure 9.
One of the most important setup considerations with a dial indicator is to ensure
the contact point is perpendicular to the
expected motion of the object being tested. Failure to ensure a proper setup will
result in an error in measurement.
To set the contact point:
1. Follow all previous instructions about
the positioning of the support assembly, boom and dial indicator.
2. Adjust the dial indicator so that it is
perpendicular (at a 90° angle) to the
object being measured. The contact
point should touch the object, as shown
in Figure 9.
Note: If the object being measured is
cylindrical, position the dial indicator
perpendicular to both the cross-sectional axis and the longitudinal axis of
the object, as shown in Figure 9. When
the object rotates, the needle of the dial
indicator will show the lateral motion or
deviation of the object.

Zeroing the Dial
The dial can be adjusted by loosening the
dial lock. This can be helpful for making
comparison measurements or if the contact point has been set and the dial needs
to be reset to zero.
To zero the dial:
1. Release the dial by loosening the dial
lock a half turn.
2. Rotate the dial so the needle and the
zero mark line up.
3. Tighten the dial lock to fix the dial in
place.
Reading the Dial
The dial is relatively straightfor ward and
easy to read.
• Every tick on the outer rim of the dial
represents 1⁄1000" or 0.001". One complete revolution of the large needle is
equal to 1⁄10" or 0.1".
• To read the dial as a whole, read the
value of the small dial first, and then
add the value of the large dial. The dial
in Figure 10 shows a reading of just
over 0.886".

Figure 10. Reading a dial measurement.
Adjustable Markers
The rim of the dial indicator is fitted with
two adjustable markers, which can be
moved even with the dial locked in position. These are very useful when performing range testing. Figure 10 shows one
of the adjustable markers at the 0.083"
position.
• The small dial indicates the number of
full revolutions made by the large dial
needle; each full revolution is equal
to 1/10" or 0.1". If the needle is situated
between two numbers, then the dial is
read as if it equalled the lower number.
For example, if the dial needle was
resting at any point between four and
five, the dial reading would be 4⁄10" or
0.4".
Note: It is important to remember the
small dial needle rotates counterclockwise.

SECTION 5: CALIPER
General Usage Tips
• Use the thumbwheel to open and close
the caliper.
• Always keep the jaws of the caliper
clean and free of dust, grease, oils
or grit. The calipers are accurate to
0.001", and even something as small
as a grain of sand or human hair can
cause a false measurement.
• Never drop, mishandle or otherwise jar
the caliper. Jarring can damage vital
internal components and cause the
caliper to provide false measurements.
• Always store the caliper in a safe place
where it will not be bumped by or
beneath other objects.
Zeroing the Dial
Locking the Caliper
The caliper lock can be tightened at any
point to prevent the jaws from opening
or closing. This is useful for per forming
manual measurement comparisons. The
caliper can also be partially tightened to
provide greater resistance, alllowing for
more precise manual measurements. The
caliper lock is shown in Figure 11.

The dial can be adjusted by loosening the

To zero the dial:
1. Release the dial by loosening the dial
lock a half turn.
2. Rotate the dial so the needle and the
zero mark line up.
3. Tighten the dial lock to fix the dial in
place.

Reading the Caliper
The caliper is ver y straightforward and
easy to read. Reading a measurement is
the same for both internal and external jaw
measurements and depth gauge measurements.
• Every tick on the caliper dial represents
1
⁄1000" or 0.001". As with the dial indicator, each full revolution of the needle
is equal to 1⁄10" or 0.1". The dial ticks
are separated into units of ten for easy
reading.

Figure 12. Reading a caliper measurement.
• The caliper ruler is marked with increments of 1⁄10" or 0.1". For every ten
ticks, there is a raised number indicating 1" or one full inch. As the caliper
jaws are opened, the ruler becomes
visible to the left of the caliper dial.
Read the numbers closest to the inner
edge of the right caliper jaw when taking a measurement.
• To take a measurement, first read
the rightmost raised number (if any)
to the inner edge of the right caliper
jaw to determine the number of whole
inches. Next, read the rightmost lower
number to the left of the jaw edge for
1/10" or 0.1" increments. Lastly, read
the dial itself to determine any remainder. Figure 12 shows a caliper set to
2.147".
