How To Read A Micrometer

It is very important that you learn all you can on how to read a micrometer. This will help you understand the results that this powerful device will give you when you use it.

A micrometer is a piece of equipment fitted with a calibrated screw, which is employed extensively for accurate measurement of small distances.

Using a micrometer, sometimes informally referred to as mike, is a fairly simple task if one practices how to read a micrometer properly.

There are several who use electronic means for measurements, which are supported by digital readouts; however, a micrometer continues to be an ideal instrument to use when it comes to precision measurement.

How to read a micrometer is a learning activity that requires practice to master the skill. Additionally, measurements those are way too small to be read with a ruler, can be easily read with the help of a micrometer.

Micrometers are many a time used together with other metrological tools like digital caliper; dial caliper and vernier, to name a few, for measurements. 

Also, a micrometer, often referred to as a micrometer screw gauge is frequently found in the form of a caliper, such as a vernier caliper.

Moreover, one can easily find a micrometer fitted with a dial indicator, wherein the latter make it very easy to obtain precise measurements of minute linear distances.

The learning activity of how to read a micrometer primarily involves verifying that the micrometer, with its jaws closed, reads a zero. If the micrometer does not read zero, one should make the necessary adjustments to recalibrate it.

Next, the article that is to be measured should be positioned properly between the two sides, with the anvil face on one and the spindle face on the other.

The rachet is to be rotated clockwise until the article is locked in, in between these two faces and one hears the rachet making a clicking sound.

Once this sound is heard, it means that the rachet cannot be tautened further and now the tool is ready for the measurement to be taken.

One can employ the metric system to understand how to read a micrometer. In this case, the spindle of a regular metric micrometer is equipped with two threads for every millimeter, which is equal to a 1000 micron.

This means that a single entire revolution causes the spindle to shift through a distance of half a millimeter, which in other measuring terms is 500000 nanometer.

The micrometer thimble is set with 50 graduations, with every graduation being 0.01 millimeter, which is 0.001 centimeter. Therefore, the final reading is an addition of two numerical.

The first is the number of millimeter divisions seen on the sleeve scale and the other is the specific division obtained on the thimble that corresponds with the sleeve’s axial line.

To explain it further, an example is stated here. If the graduation is at 10, and a further sub division of 0.5 is seen, and graduation 30 on the thimble corresponds with the sleeve’s axial line, then the reading will be 10+0.5+0.30, which equals to 10.8 millimeters, which is 0.0108 meter.

One very convenient option for those who want to learn how to read a micrometer is to practice reading micrometers online on websites which present micrometer reading exercises.

Once, people become experts, they can turn towards practicing with an actual micrometer, to enhance their skills further. You can also make use of the reliable laser measuring device to get more accurate measurements.
