There are 4 types of measurement that a digital caliper can perform: external, internal, depth, and step. Learn how to use a caliper to measure each. Also included in this presentation are tips for using a handheld durometer gauge. For more information, contact Timco Rubber today at 1-800-969-6242.

1. HOW TO USE A DIGITAL CALIPER
The main use of a digital caliper is to measure the distance between
2 opposing sides.
Please remember to always check for zero point before starting to
use your digital caliper.

2. TO CHECK THE ZERO POINT
Make sure the jaws are clean, move the
movable head towards the stationery jaw so
that the two jaws surface completely contact
each other.
Apply small force using your thumb so that
the two jaws do not separate from each
other.
Check the Digital Display for zero
reading, push the zero point button to set to
zero. Your digital caliper is ready to use.

3. There are 4 basic types
of measurement which a
Digital Caliper can
perform

4. 1. EXTERNAL MEASUREMENT
Using the lower jaws, the
external dimension can be
measured. Place your work
piece in between the two
jaws. Push the movable
head towards the work
piece. When both jaws
touch the work piece, hold
lightly, make sure the jaws
of the digital caliper are
perpendicular with the work
piece, then check the
digital display for
dimension.

5. 2. INTERNAL MEASUREMENT
Internal measurement can be
obtained using the smaller
upper jaws. Place the two
small upper jaws inside the
work piece to be measured.
Pull the movable head so that
the two small jaws separate
from each other and touch the
opposite sides of the
measured portion. Make sure
the 2 jaws are perpendicular
with the hole to be measured.
Hold lightly and read the
dimension appeared on the
digital display.

6. 3. DEPTH MEASUREMENT
You can measure the depth of the
hole on your work piece using the
probe, which is attached to the
movable head, and the slice, which is
along the center of the digital caliper
body. The measurement can be
obtained by moving the probe to the
lower end of the measured area.
Make sure the bottom of the digital
caliper is sitting on the upper end of
the measured area. Hold lightly and
steadily, make sure that the digital
caliper is perpendicular with the work
piece, then take the dimension on the
digital display.
Note that depending on the
manufacturer, a few digital calipers do
not come with the probe.

7. 4. STEP MEASUREMENT
As you move the movable head
of the digital caliper, notice that
at the back of the head, there is
a step which also moves. This
step can be use to measure the
step on your work piece. Put the
movable step measuring face of
your digital caliper on the upper
step of your work piece and the
stationary face of the digital
caliper on the lower step of your
work piece to be measured.
Make sure the faces of the
digital caliper and the step faces
are perpendicular with each
other. Hold steadily and take the
dimension on the digital display.

8. USING A HANDHELD DUROMETER GAUGE

9. WHY DO WE USE A DUROMETER GAUGE?
TO VERIFY THE
HARDNESS
OF THE MATERIAL

10. DUROMETER GAUGE FUN FACTS….
1. We use a Shore A durometer gauge for softer rubber materials
2. The Shore D durometer gauge is used for harder rubber materials
and plastics.
3. A durometer gauge is considered an indicator.
4. The accuracy of a durometer gauge is +/-2.
5. We get our gauges calibrated once a year except for Denise and
Greg. Theirs are done two times a year.
6. The test buttons that are with your durometer gauge should check at
60 durometer.
