SLIDE 1:
INTRODUCTION
Title: Introduction to Vernier Caliper
Content
Welcome to the training session on Vernier
Caliper
Importance of precise measurements in
engineering and manufacturing
Overview of today's session
Title: Understanding Vernier Calipers
Slide 2:
What is
a Vernier
Caliper?
Content
Definition of a Vernier Caliper
Key components: main scale, vernier
scale, jaws, depth rod, locking screw
Types of vernier calipers
Slide 3: Parts of
a Vernier
Caliper
Main scale: fixed scale marked in
millimeters/inches
Vernier scale: sliding scale for precise readings
Inside jaws: measure internal dimensions
Outside jaws: measure external dimensions
Depth rod: measure depth of holes
Locking screw: holds the scales in place for
accurate measurement
Title: How to Read a Manual Vernier
Caliper
Slide 4:
Reading
a Vernier
Caliper
Content
Align the zero of the vernier scale with
the main scale
Note the main scale reading just before
the zero of the vernier scale
Find the vernier scale division that aligns
perfectly with any main scale division
Calculate the final measurement
Slide 5:
Example
of Reading
a Manual
Vernier
Caliper
Title: Reading Example
Content
Main scale reading: 3.2 cm
Vernier scale reading: 0.08 cm
Final measurement: 3.2 cm + 0.08 cm
= 3.28 cm
Visual example with an image of a
vernier caliper
Title: Using Digital Vernier Calipers
Slide 6:
Digital
Vernier
Calipers
Content
Turning on the digital caliper
Zeroing the caliper before measurement
Taking a measurement
Reading the digital display for the final
measurement
Title: Techniques for Accurate
Measurements
Content
Slide 7:
Measuremen
t Techniques
Ensure the caliper is clean and free
from debris
Use consistent pressure while
measuring
Measure at right angles to the object
Repeat measurements for accuracy
Slide 8:
Common
Mistakes
and How
to Avoid
Them
Title: Avoiding Common Mistakes
Content
Zero error: ensure the caliper reads zero
when fully closed
Parallax error: read the scales directly from
above
Misalignment: ensure the object is properly
aligned with the jaws
Applying too much force: gently slide the
jaws to avoid damaging the caliper or object
Title: Hands-on Practice
Slide 9:
Practical
Exercise
Content
Practice measuring objects with both manual
and digital vernier calipers
Record and compare measurements
Discuss any difficulties and how to overcome
them
Title: Summary and Questions
Slide 10:
Summar
y and
Q&A
Content
Recap of key points: parts, reading techniques,
and best practices
Importance of accuracy and precision in
measurements
Open floor for questions and clarifications
