How to use a caliper??

A caliper has two jaws, one fixed, the other sliding. Move the sliding jaw by pressing your thumb on the bump on the bottom. Many calipers also have a knurled wheel that makes moving the jaw easier. An electronic digital caliper has some buttons on the readout. One of them turns the caliper on; one sets the caliper to zero; and one switches from inches to millimeters. The precise location of each button and how it is labeled varies from model to model. Yours might have additional buttons.

The First Step

Before you take a reading—and I mean before you take every reading—close the caliper and make sure the reading is 0.000. If not, do this:

1. Open the jaws about three quarters of an inch. Then use the thumb of your free hand to wipe off the mating surfaces of the jaws.

2. Close the caliper again. On an electronic digital caliper, if the reading is not 0.000, press the zero button so that it does read 0.000. To zero a dial caliper, rotate the bezel so that the needle points to 0.

Four Basic Readings

Your caliper can take four kinds of readings: outside, inside, depth, and step. Any caliper, whether it is a vernier caliper, dial caliper, or electronic digital caliper, can take these measurements. Let’s take a look at how you take each of those readings.

Outside Measurement

Outside measurements are the most basic you can do with a caliper. Slide the jaws open, place the caliper over the object to be measured, and slide the jaws until they contact the workpiece. Read the measurement.

It’s easy, but if you don’t do it correctly the measurement will not be accurate. If the calipers are not straight (that is, perpendicular to the workpiece) the measurement will not be accurate. Likewise, if there is dirt on the jaws or the workpiece the measurement will not be accurate.

Inside Measurement

The smaller jaws on the top of the caliper are used for inside measurements. Slide the caliper closed, place the inside-measuring jaws into the space to be measured, and slide the jaws apart as far as they will go. Read the measurement.

It’s a little harder to keep things lined up correctly when you are taking an inside measurement. Be sure that the calipers are not cocked, or you will not get an accurate measurement.

Depth measurement

As you open the caliper the depth blade extends out of the far end. Use this blade to take depth measurements. Press the machined end of the caliper against top of the hole you want to measure. Open the caliper until the depth blade contacts the bottom of the hole. Read the measurement. It can be tricky keeping the caliper straight over the hole, especially if only one side of the caliper is resting on the workpiece.

Step Measurement

Step measurement is the hidden use of a caliper. Many instructions skip this important use. But once you know about it, you will find many uses for step measurement.

Open the caliper slightly. Place the sliding jaw on the upper step of the workpiece , then open the caliper until the fixed jaw contacts the lower step. Read the measurement.
