There are many types of calipers on the market, but the two most common types are digital and dial. Each type of caliper has its own strengths and weaknesses, so it’s important to understand the differences before buying one. In this article, we’ll take a closer look at each type of caliper and help you decide which is right for you.
What is a dial caliper?
A dial caliper is a precision measuring tool that uses a vernier scale to measure distance. The vernier scale is a series of small lines spaced differently from the main scale, allowing for more precise measurements. Dial calipers also have a large dial that can be used to make quick, rough measurements.
What is a digital caliper?
A digital caliper is a precision measuring tool that uses a digital display to show the measurement. It typically has a vernier scale and a large digital display showing the measurement in metric and imperial units. Digital calipers are more expensive than dial calipers, but they’re also more accurate and easier to use.
Four types of measurements
Four main types of measurements can be taken with a dial or a digital caliper:
Outside measurement
It is the most common type of measurement taken with a dial caliper. To take an outside measurement, simply place the caliper’s jaws around the object you want to measure. The large dial will give you a quick, rough measurement, while the vernier scale will give you more precise measurement.
Inside measurement
To take an inside measurement, reverse the caliper’s jaws so that they’re facing inwards. Next, place the jaws around the object you want to measure, and then read the measurement from the dial or vernier scale.
Depth measurement
To take a depth measurement, you will need to use the depth probe attached to the caliper. Place the tip of the depth probe into the object you want to measure, and then read the measurement from the dial or vernier scale.
Step measurement
To take a step in measurement, you will need to use the depth probe and the caliper’s jaws. First, take a depth measurement of the object you want to measure. Then, place the caliper’s jaws around the object and take another measurement. The difference between these two measurements will give you the width of the step.
How to use dial and digital calipers?
Using a dial caliper is relatively easy, but there are a few things you need to keep in mind. First, make sure that the caliper jaws are clean and free of any dirt or debris. It will ensure that the caliper takes accurate measurements. Second, be sure to use the vernier scale when taking precision measurements. To use the vernier scale, line up the zero mark on the vernier scale with the zero mark on the main scale. Then, read the measurement from the vernier scale.
Digital calipers are very easy to use. Simply turn on the caliper and select the mode you want to use (outside, inside, depth, or step). Then, place the caliper’s jaws around the object you want to measure. The digital display will show the measurement in both metric and imperial units.
Troubleshooting
If you’re having trouble using a dial or digital caliper, here are a few tips that might help:
First, make sure the caliper jaws are clean and free of debris. Make sure the object you’re measuring is placed squarely between the caliper’s jaws. If you’re taking an inside measurement, make sure the jaws of the caliper are reversed so that they’re facing inwards.
When taking a depth or step measurement, ensure the depth probe is properly positioned and not obstructed by debris. Try using a magnifying glass if you’re having trouble reading the dial or digital display.
Calibration
It’s important to make sure your caliper is properly calibrated before taking any measurements. Most calipers have a calibration screw that can be used to adjust the dial or digital display. Consult your caliper’s instruction manual for more information on how to calibrate your specific model.
How to read measurements on the dial or digital calipers?
The most important thing to remember when taking measurements with a caliper is that the caliper’s jaws must be flush with the object you’re measuring. If they’re not, the measurement will be inaccurate.
First, make sure that the vernier scale is lined up with the main scale to read a dial caliper. If it’s not, you can adjust it by turning the knob at the end of the caliper. Once the vernier scale is lined up, read the measurement from the main scale and the vernier scale.
To read a digital caliper, simply press the button on the side of the caliper to turn it on. The digital display will show the measurement in both metric and imperial units.
Difference between the dial and digital calipers
You should be aware of several key differences between the dial and digital calipers before you buy one.
Accuracy
Dial calipers are less accurate than digital calipers because they rely on the user to read the vernier scale correctly. Digital calipers are more accurate because they use a digital display to show the measurement.
Ease of use
Digital calipers are easier to use than dial calipers because they have a digital display that shows the measurement. Dial calipers are more difficult to use because the vernier scale can be difficult to read.
Price
Dial calipers are less expensive than digital calipers.
Which type of caliper is right for you?
The type of caliper you need will depend on the measurements you need to take. For example, if you need a caliper that is easy to use and accuracy is your top priority, then a digital caliper is the best choice. On the other hand, if you only need to take quick, rough measurements, then a dial caliper is good.
