Best Digital Caliper Buying Guide

Before you decide on the best digital caliper for your needs, it helps to understand more about this tool.

Introduction of Calipers

Digital calipers allow for a high level of precise measuring when you desire to get the exact reading. There are three main types of calipers available: Vernier, Digital and Dial.

A vernier caliper offers length and diameters down to 0.0005 inches so it is the most precise you can purchase. With computerized calipers, readings are shown on the LCD screen to make it easier for you to understand.

With both the dial and vernier variety, you need to evaluate the measurements.

Parts of a Digital Caliper

Let’s look deeper at what parts make up the best digital caliper.

Depth Gauge – Helps to measure an object’s thickness as well as the depth of a hole.

Locking Screw – Prevents the caliper’s jaws from moving during a measurement.

Step Gauge – Measures the distance from the edge to the point of an object.

ABS Button – Temporarily sets your measurement to zero.

Inside Jaws – Measures the dimensions inside. These jaws are delicate and prone to breakage, so care must be used.

Outside Jaws – Measures the dimensions outside of the object.

On/Zero Button – Sets the current position to zero plus powers the unit on.

In/mm Button – Switches measurements from inches to mm.

Battery Compartment – a place where the batteries are held to operate the digital caliper.

How to use the Best Digital Caliper

If you’ve never used the best digital caliper, we have the steps you need to make it easy.

Start by Zeroing the Calipers

You must zero the calipers prior to taking any measurements. If you decide to skip this, your measurements won’t be accurate. Simply press the zero/on button to get started.

To Measure Outside Dimensions

Make sure you use the inside jaws on the object. You need it to be parallel to the jaws or you won’t get an accurate reading. The inside jaws are also helpful with measuring thickness. Just make sure your object is perpendicular to the jaws.

To Measure Inside Dimensions

Use your outside jaws on the object. The object must be perpendicular to the jaws.

To Measure Depth

Use your depth gauge to get the depth from one surface to another. Your calipers must be perpendicular to the surface you are measuring.

To Measure Step

Use the step gauge and measure the distance from one edge to the edge above it.

Take Comparative Measurements

When you zero the calipers in place during a measurement, you can compare those dimensions to another.
