How to Use a Vernier Caliper
Vernier calipers are measuring tools used mainly for measuring linear dimensions. These calipers come in handy in measuring the diameter of circular objects. Their circular jaws fit securely on either side of the circumference of round objects. Vernier calipers have two types of scales- a fixed main scale and a moving Vernier scale. Vernier calipers score well over standard rulers because they can measure precise readings up to 0.001 inches. Let’s get to know more about the device!
Range of
Vernier Calipers:
The maximum
capacity of a Vernier caliper is the difference between the smallest and
largest measurement reading. Usually, it is the total length of the main scale.
Vernier calipers, generally, have a range of 300 mm. Vernier calipers of
smaller ranges are also widely available in the marketplace.
Vernier
Reading:
Vernier
reading is the smallest measurable distance captured by a Vernier caliper. It
is also termed as "Resolution" of the Vernier caliper. Imperial
Vernier calipers have a resolution of 0.001 inches. The resolution of metric
Vernier calipers varies from 0.02mm to 0.05mm.
Tolerance:
Tolerance or instrument error refers to the accuracy of Vernier caliper readings. Vernier calipers are generally used for low-tolerance measurement readings. Low tolerance measurement readings are accurate and reliable because there is a minimal chance of error. Vernier calipers have two different types of scales- a fixed main plate and a moving Vernier scale. The significant scale usually is in millimeters.
Vernier
Measurement:
Vernier
measurement reading is the tiniest measurable distance noted by a caliper. It
is also known as the "Resolution" of the device. The answer of metric
Vernier calipers varies from 0.02mm to 0.05mm. The key is usually indicated at
the end of the Vernier scale.
