How to use the 2022 caliper

How to use the caliper

How to use the caliper very easy to do, maybe you are already familiar with rulers, clocks and weight scales which are measuring tools.

Similarly, the caliper is used to measure the outside or inside diameter of an object, while the ruler is to measure a flat surface.

Then the caliper can be used to be able to measure the length of objects that are not only flat, but humans will certainly need a length measuring instrument.

Of course it is more detailed to be able to measure the length of an object shape, so to solve this need requires a caliper measuring instrument that has its own characteristics.

In its use and in measuring an object, especially when studying physics, the measuring instrument has even been introduced since sitting in junior high school.

But you don’t have to worry about how to use caliper because we will explain it for you as follows.

1. caliper function

caliper function

Before going to how to use the caliper, you must know what are the functions of the caliper? In practice the caliper has a function that is quite helpful for humans.

To be able to measure the length of an object, this measuring instrument was created to answer unsolved problems.

Like being able to measure the shape of objects not only from a flat surface like a measuring tool using a ruler, because in fact we also need precise and accurate measuring tools.

There are several functions of the caliper, which are as follows:

  • Serves to be able to measure an object from the outside by being flanked.
  • Serves to measure from the side in the form of an object which is usually a hole such as a pipe by stretching it.
  • Serves to measure the depth of a gap or hole in an object by plugging or piercing into the measuring instrument.
  • Used to measure the thickness of an object.
  • Functions to measure the diameter in the shape of an object using a fixed jaw and an upper sliding jaw.
  • Functions to measure the depth of an object using the bottom measuring rod, for example, the depth of a tube, a small hole or a relatively small difference in height.
  • There are two scales, namely the main scale and the nonius scale.

2. Types of Calipers

Types of Calipers

Before you understand how to use a caliper, you must know the types of caliper so that you can use several types of caliper according to your needs.

The types of caliper are as follows:

1. Analog or Manual caliper

This type of caliper is usually used for practicum in schools or school laboratories, because it is only for practical purposes.

How to use this one caliper is quite difficult, namely manually, it requires more accuracy when using it.

Meanwhile, to be able to know the measurement results, you need to calculate it manually first.

2. Digital caliper

This one caliper has been developed from the previous type which is still analog or manual, maybe you will find it very difficult to find a digital caliper at school or.

A school laboratory, but this caliper has a screen that can display the value of the measured object without having to calculate it manually.

However, this digital caliper will greatly facilitate and speed up when measuring the shape of objects, for example in large quantities.

However, in terms of price, this digital caliper is more expensive than the analog type.

3. Watch caliper

How to use this one caliper is to read it using an analog size needle attached to the face or using a stopper.

This caliper uses a measuring clock instead of the nonius scale when interpolating the index line to the measuring rod scale.

4. Altitude caliper

This height caliper is a type of slide ruler that functions to be able to measure height, but the caliper has a measuring jaw that moves vertically.

In a bar that is scaled perpendicular to its base, the measuring jaw at the caliper is parallel to the reason so that the measuring line is perpendicular.

With the surface on which the base is placed, that is why users of the caliper need a flat reference surface such as a flat tabletop.

3. Parts of the Caliper

Parts of the Caliper

In order for you to know how to use a caliper, you must know the parts of a caliper and their function if you already understand the parts in a caliper.

Of course, it will be easy to use a caliper to measure the diameter or shape of certain objects, for more details, just see below.

There are several parts to the caliper measuring instrument, namely as follows:

  • Inner jaw: Consists of sliding jaws and fixed jaws that can function to be able to measure the inside such as the diameter or gap of an object shape.
  • Outer Jaws: Consists of two jaws, sliding and fixed jaws that function to measure the outside, for example the diameter, width or length of certain shapes.
  • Stalk Depth Measure: This section serves to measure the depth of the hole in a particular object.
  • Main Scale: This section serves to state the results of the main size which is usually expressed in cm or inches, usually the length of the main scale is 15 to 17 cm.
  • Nonius scale: This section serves to add an extra level of accuracy in measurements which are usually expressed in inches or mm.
  • Locking Bolt: the locking bolt in the caliper serves to hold it in place so that the object being measured can be held or not released and the scale does not shift when it is being measured.

After knowing the functions, types and parts of the caliper, then you must know how to use and read the measurement results on the caliper.

If you are able to measure the diameter or depth of an object, but can’t read or interpret the results, it’s useless.

How to use the caliper is as follows:

  • First, prepare the object or object to be measured, such as marbles, coins or so on.
  • If you have opened the jaw, slide it into the caliper on the left side until it is really tight so that it can produce an accurate size.
  • But make sure again that both jaws are closed and the scale shows zero, things like this you need to pay attention to so that there is no measurement error or so-called zero error.
  • After that loosen the locking bolt and pull the sliding jaw to the right side until the object you want to measure can be properly placed between the two jaws.
  • Then place the object between the two jaws and make sure again that the position is appropriate and correct.
  • Then pull the sliding jaw to the left side to flank the object to be measured and then turn the locking bolt until you hear a click sound.
  • Next you pay attention to the line that is squeezed between the upper and lower scales or the nonius scale, then find the number that connects straight with the line from the nonius scale.
  • At this stage calculate the measurement results obtained by adding up the two numbers, then calculate the diameter of the object being sought.

The final word

That’s the whole content of our article this time about how to use caliper correctly and in shape for those of you who don’t know how to use it.

Not only how to use it, but you have to understand the parts and types of the caliper measuring instrument.
