Features to Look for Before Buying

A digital Vernier caliper is an instrument you use to measure the internal and external dimensions of an object. And a machinist will use these in many applications, including CNC, routing, and others.

Vernier calipers measure accurately to one-hundredth of a millimeter or one-thousandth of an inch, which makes it more accurate than any standard ruler.

That is to say that it works like a ruler but has more implications and has a better standard of measuring.
Electronic or digital calipers have increased in popularity these days.

This is because they are much simpler to use and measure faster, not to mention more accurately than an average ruler.

With different features like sensors, large LCD screen, zero function, measurement conversion, it is easy to see why machinists are leaning towards these more and more for their projects.

When buying a digital caliper, take into consideration the environment you will be using it in. Find out the functions and how they can help you with your job or projects.

Depth Gauge

Depth Gauge

This measures the depth you’re making and the thickness of the material you’re working on. Basically, if you have a caliper, it is usually because of the ruler-like feature on it. Most of the best digital calipers read out the measurement on the screen, so you don’t need to worry about the accuracy of the measurement.

Locking Set Screw

A locking screw helps stabilize the measuring jaws. You can use this if you want to retain the last measurement you took.

This is usually a knurled knob on top of the LCD screen and on the big jaw of the caliper. You can use it as a manual backup to the last measurement you took.

Step Gauge

A step is the measurement from the edge of a certain object. It is crucial to note this, especially when you’re connecting two components together.

With a step gauge on your caliper, it will be easy for you to measure out different aspects without using different tools.

Outside Jaws

You use these to measure the inside of the item or object. When buying one, be sure that there are no flaws in the jaws. This is to make sure that your measurements are as accurate as possible.

Thumb Roller

This is a simple knurled knob that gives you more control over the caliper. Usually, this is located on the lower part of the LCD screen. The basic function of this is to provide the user with a better grip when using the best digital calipers (learn how digital calipers work here).

Inside Jaws

You have to be sure that you’re getting a nice and flush build on these. You should expect the inside jaws to have clean and precise construction, which will provide the most accurate measurement possible.

See to it that they do not have any dents or glinting, as these will compromise your measurements.

Zero Function

Machinists need to do a lot of measurements, and sometimes you need to reset the measurement to zero in order to get a better one. This is called a differential measurement.

Without a zero function on your caliper, you will need to list the previous measurement and then hope that you can get the next one more precisely.

While you can do this with a set screw, a zero function is more practical and has less room for mistakes.

LCD Screen Display

Everybody loves a bright display. It is a good way of determining if the overall construction and build of the caliper are as good.

The LCD should have a high definition display, which means the numbers should have deep coloring and should be visible in any light condition.

What the LCD displays should also be taken into account. It should display the standard measurements (inches and millimeters), and it would also be a great addition if there is a fraction display option.

Power Saving Mode

A digital device will need batteries to run it. It is both practical and convenient because you don’t have any wires or cables restricting your movement.

You just need to make sure that your caliper will have a power-saving mode. As simple as it seems, it can save a lot of battery power. This is simply a feature that shuts off the device after a set time of not using it.

Rigid Construction

Your devices should also last a long time. After all, what’s the use of having accurate measurements if you can’t use them for a long time?

Well-built calipers are made from stainless steel. Aside from being the ideal material for precision instruments, stainless steel can also provide a tough exterior or overall build to devices.

This material is generally resistant to rust and can withstand most accidental blows or impacts.

IP Rating

Having an IP rating means it meets an international standard for devices that determines how well they fare against certain external factors.

Most calipers will have an IP54 rating, which means they can withstand or resist most accidental spillage and protection from dust particles.

This is crucial for precision instruments since these tend to have sensitive components that need such protection.

It is also a reflection of the manufacturer’s commitment to quality because they constructed the device to meet certain standards.

User-Friendly Features

A caliper is a simple and basic tool that does a crucial job. So, look for one with all the details and important things you need.

Always look for the basic functions first before any other fancy features because that’s what you really need.

Components of a Caliper


It doesn’t take a lot to get used to a digital caliper. After all, these are designed to provide you with the most accurate measurement with all its specs and features.

One of the things to consider so that you can use a caliper rightly is to familiarize yourself with the parts and their uses.

The most critical components of a caliper are:

Outside Jaws

In essence, this is what makes the caliper what it is. These large jaw-like protrusions are designed this way so that they can measure the outside diameter, thickness, and even length of the object.

To get the best result, make sure that the object you’re measuring is as close to the ruler as possible. This will help keep the caliper stable, and at the same time, you have a visual guide of how close the jaws are on the object you’re measuring.

Inside Jaws

These are the smaller jaws behind the outside jaws that are meant to measure the inside dimensions as well as the cavity length. They work with the same principle as the outside jaws.

Depth Gauge

As the name suggests, this measures the depth of the cavity or hole you made.

For additional functions, you will also find these features that can help with using the caliper.

  • Thumb Roller
  • Locking Set Screws
  • Zero Mode
  • Inch/Millimeter/Function – used to change the unit of measurement

Right Way to Use a Caliper

Once you’ve familiarized yourself with these, you can operate the caliper with confidence. Here’s how you can operate a digital caliper:

  • Wipe the caliper before using it.
  • Close the jaws so that they are in contact, or the LCD screen reads zero.
  • Select the desired unit of measurement.
  • Test the stability of the jaws by opening and closing it a couple of times. Make sure that it goes back to zero every time you close it.
  • Clean the object you are measuring, making sure that there is no foreign object on it that can alter the measurement.
  • Measure by clamping the jaws on it. Remember that it should not be tilted at an angle and should be square with the object.
  • Do not force the measurement. Let the natural distance reflect on the caliper. For example, if the unit measures .200”, don’t press it to reach .200”.
  • Once you’re finished with measuring and recording it, check the caliper if it goes back to zero as a review of your measurement accuracy.
  • Clean up the jaws and the caliper before storing it.

Care and Maintenance Tips

It’s not hard to clean up a caliper. But since it is a precision instrument, proper care and maintenance should be done to it to keep it working well and lasting a long time.

Here are some care tips for your best digital calipers;

  • Don’t throw or drop your caliper.
  • Avoid putting it on areas where it may be damaged or broken.
  • It should not be laid on a detritus-filled surface.
  • Keep the measurement within the limits of the caliper.
  • Don’t use it for other than its intended use.

Here are some maintenance tips for your caliper:

  • Wipe the surfaces before and after using the tool. This prevents dust and other materials from affecting the accuracy of the measurement.
  • To clean the jaws before using them, you can use a piece of paper (see how thick paper is) to do this. Simply clamp the jaws shut on the paper and pull. This will remove any foreign material that may interfere with an accurate measurement.
  • When not in use, return the calipers in their proper storage.
  • Use them only in stationary objects.
  • Even if the calipers have an IP54 rating, it would still be a good idea to keep them from water and dust.
  • Check the calibration and battery power periodically.
