How does an 8” digital caliper work: Working principle

Before we discuss the maintenance of digital calipers, you must understand how it works. Proper knowledge of the workings of a digital caliper will be a background to how to care for its delicate parts.

Digital calipers use capacitance sensors that stretch along the whole length of the beam. Small changes to the distance between the jaws trigger an electric charge which is detected by sensors placed in the caliper.

The electric charge detection and sensors work efficiently in the caliper because of an engraved rectangular plate sitting on a glass or copper strip. In addition, circuit boards are placed underneath the moving jaws of the caliper. These boards alongside the engraved plates form the network of capacitors.

As the jaw slides along the main scale, the rectangular plates, line up properly and also misalign; thus causing a difference in the amount of electrical charge present between the plates. The sensors pick up the charges in the earlier described mechanism and send them to a chip in the caliper.

This chip interprets the charges and creates the readings shown on the LCD.

The steps to follow in using a 8 digital caliper

Having discussed the working principle of digital calipers and how it works, let’s discuss how to actually put one to use. Be rest assured, using a digital caliper requires very easy-to-follow steps. However, not following these steps adequately can lead to inaccurate measurements.

First and foremost, always start the readings from zero. Although the best digital calipers will reset to zero every time they are turned on, otherwise, you will have to manually press the zero button before each use.

The next step involves positioning the jaws correctly because of the numerous positions the jaws can assume; especially under different measuring conditions.

For instance, if you want to measure outside dimensions, you must position the inner part of the jaw to parallel to the object being measured. This way, you can get the most precise measurement.

Also, if you want to measure how thick an object is, you place the inner part of the jaws and the object perpendicularly to each other.

On the other hand, if you want to take measure inside dimensions; you must place them outside of the jaw and the object perpendicularly to each other. For depth measurements, you must not just position the jaw rightly, you must also engage the depth gauge.

Here, the right positioning for the jaws is perpendicular to the surface that is about to be measured.

Sometimes, calipers are used in measuring steps, and you do this correctly by using the step gauge. It accurately helps the caliper measure the distance between one edge and the edge. Lastly, comparative measurements are taken by resetting the caliper to zero while the jaws are still in place.

 

The things to look out for in the Best Digital Caliper

Having discussed extensively the importance of having the best digital caliper, you are most likely wondering how do I get my hands on one? Look no further, the answers are here!

As much as digital calipers are widely used in metalworking, carpentry, mechanical engineering, and other handiwork that require precise measurements, many do no know what to look out for when purchasing one. Here are few features an 8” digital caliper should have;

1. Depth gauge

A depth gauge ensures you can measure how deep a hole is and also the thickness of an object.

2. Locking screw

it is useful in keeping the caliper jaws in place so that accurate readings are taken.

3. Step gauge

As described earlier, helps to measure between edges of an object.

4. ABS button

Remember having to reset to zero? This button makes that possible as it allows to you reset any measurement to zero, but only temporarily.

5. Outside jaws

It helps to take readings on the inside dimensions of an object.

6. Inside jaws

Inside jaws are useful for taking measurements of the outside dimensions of an object. Remember, you must care for these jaws otherwise you risk damaging them and having to work with inaccurate readings, something you do not want for the success of your project.

7. Zero button

Unlike the ABS button, this is useful before you start taking readings as it resets your current position to zero. It is usually the same as the power on button (peradventure you do not see a designated button).

8. In/mm button

Converts readings between two metric units (inches and millimeters). The best digital calipers also can convert readings to fractions.

9. Automatic off

Engrossed by the project at hand? don’t worry about having to turn off all your devices.

The automatic off feature present on the best digital calipers only saves battery power by turning the caliper if idle for an extended duration. Usually, after 5 minutes, most calipers will turn off.

10. Stainless steel construction

Calipers made from other materials are sometimes flimsy and do not have a smoother finish like calipers made from stainless steel. As a result of the stronger build, they often provide more accurate readings although with negligible differences to other types.

11. Large LCD screen

Although not much of a deal-breaker makes reading measurements easier and reduces the risk of error (at least on your path).

12. IP54 protection

Do you trust your ability to care for the caliper? If in doubt, purchase a unit with this feature.

Because it protects your device from damages caused by dust, dirt, water splashes, and insects. Although it increases how much you have to pay from such units.

What’re a few extra bucks compared to having a long-lasting and functional caliper for your projects?

In essence, the best digital calipers will be easy to operate for all sorts of needs, if you know what to look out for. A readable display, a smoother caliper jaw movement, is nothing but features to improve your productivity.

Why and how do I care for a digital caliper?

In reiteration, digital calipers are delicate precision tools and must be looked after properly. Otherwise, the essence of purchasing a digital caliper is voided: as the device will take inaccurate measurements.

You do not want to hamper the success of your project because you missed out on a few maintenance tips, do you?

Although there is more to the maintenance, proper care is ensuring the caliper is adequately switched off and stored properly after each use. Some modes have custom-made cases, ensure you put these extra features to use.

Some other maintenance steps you can follow to keep the accuracy of your caliper intact include the following;

  • Periodically, oil the shaft lightly and wrap the caliper in corrosion-resistance materials or store it in designated cases.
  • Keep the caliper in a low humid environment.
  • Store away from the reach of corrosive chemicals.
  • Archaic but true, never use the caliper for any purpose it was not intended for.
  • As much as possible, avoid dropping the caliper; this can damage the calibration.
  • While in the workshop, avoid placing heavy tools on top of the caliper.
  • Keep away from excessive heat.
  • Periodically check the battery for optimal performance.
  • If you will not use the caliper for an extended period in the advent of vacation or any other travels, remove the battery to prevent damages from leakage and corrosion.

FAQs About Digital Calipers

What benefits do digital calipers offer regular ones?
