Tighten the screw so that you can remove the workpiece and get your reading. To get accurate measurements, ensure that the upper step is perpendicular to the edge of the hole, object, or workpiece you are measuring.ДЄdditionally, the fixed jaw should make contact on the lower step. Step MeasurementДЄlthough itвЂ™s the least used application of a caliper, itвЂ™s extremely helpful for many DIY projects. Turn the lock screw to tighten the jaws to remove the object and take the reading. Do this by moving the thumb screw gradually. Open the caliper until the blade touches the bottom. Then, press the machined end against the top of the object or hole you want to measure. To measure the depth, position the rod so that it is flat against both the bottom of the hole and its internal side. Depth MeasurementДЄ caliper has a depth blade that extends out of the far end. Slide the jaws apart as far as they can go and make sure that the calipers are not tilted to get better readings. Do note that it can be challenging to keep things lined up correctly when measuring internal spaces.ДЇor an accurate measurement, slide the caliper closed and place the inside jaws into the space to be measured. The smaller jaws or legs on top of the caliper are used to measure inside dimensions. Additionally, if thereвЂ™s dirt on the object to be measured or on the jaws of the caliper, the measurement wonвЂ™t be accurate. While itвЂ™s easy, you may not get accurate measurements if you donвЂ™t do it properly. To do this, you simply slide the jaws of the caliper until both ends touch the workpiece. The most basic application of a caliper is for measuring the outside dimensions of an object, say, a watch, a coin, or a screw head. This tool also comes with a depth robe and a metal sheet that you can use to quantify hole distances. You use the first pair for measuring the internal dimensions of an object, and the other pair is for measuring external dimensions. How To Get Accurate Readings With a CaliperДЄs mentioned, a caliper has two pairs of jaws. This way, you donвЂ™t end up buying one that doesnвЂ™t match your projectвЂ™s requirements. The key to finding the best digital caliper is knowing what your needs are. They are easy to use and automatically convert the readings between metric and standard measurement systems. There are different types of calipers, but the most popular are the digital versions. As you can imagine, this is enough to ensure your workpiece fits nicely within the material youвЂ™re using. The most decent ones boast an accuracy within +/-0.001 inches or 0.02 millimeters. LetвЂ™s take a closer look at how this tool does in terms of accuracy. The best digital caliper for accurate measurements will provide you with four readings: external and internal dimensions, depth, and step. While you use them for measuring different materials, how sure are you of their accuracy? A caliper is a special measuring tool that primarily consists of two adjustable legs or jaws.
