How do you read a dial caliper?

A dial caliper is easier to read than a ruler, but they’re still not the easiest things to read. It can be hard to find the numbers on the dial, especially if you have a tapered dial and the numbers are closer to one end. Try reading a dial in bright light—that can make it easier to find the numbers. After you’ve found the numbers, use a pencil and paper to record the smallest number and the largest number.

How do you read a dial caliper taper?

A dial caliper taper refers to the gradual change in diameter of the probe from the handle to the tip. If the taper is too steep, the point of the probe can scrape against the inside of the tube that holds the dial indicator. This will cause the reading to be inaccurate. To make sure the probe doesn’t scrape, insert the probe, add a spring, and lock it in place. The spring will keep the dial indicator at zero. If you still have an issue

How to read a dial caliper without the need to look?

Don't be afraid of the dial! It's easier than you might think! Look at the way the dial is laid out. There should be two gradations: one on each side of the center—this is the zero point. The minute vernier is usually located next to the zero point. Then there should be two gradations on each side of that—this is the reading point. With the dial in the center pointing down, all you have to do is count the number of lines between the

How to read dial calipers?

There are two dial calipers—one for the inside diameter (ID) and one for the outside diameter (OD). To read a dial caliper, place one jaw on top of the tube and hold the other against the tube while turning it. You can then read the number from the dial. When you have a threaded tube, you can also use a dial gauge (they’re also called dial micrometers) to read the tube’s threading.

How to read a dial caliper?

You’re now ready to actually read the caliper. Use your thumb to spin the dial around slowly clockwise or counter-clockwise while applying firm pressure to the gauge. The reading will be displayed on the dial.
