How to Buy the Best Digital Caliper

How to Buy the Best Digital Caliper

#1. Zero Button

A zero button is one of the best features in a digital caliper because it makes the process of recalibration much easier and allows you to reset the reading to zero at any point. This resetting allows for some sort of differential measurement, just like in the dial calipers.

The result of this is a more versatile unit and therefore, this feature should be highly considered.

#2. Inside and Outside Jaw

These are the most essential parts of any digital caliper because they are used to measure the inner and outer dimensions of an object.

All calipers have these jaws and it is important to handle them with care (especially the inner jaws) because once they break, your caliper is useless.

#3. Gauge

Apart from the jaws, a depth gauge, also known as a depth probe or bar, is similarly important for measuring thickness and hole depth.

A step gauge is also good to have so as to measure the length from an edge to a point on the object.

Basically, all these make the digital caliper more versatile because they give more functionality in one.

#4. Locking Screw

A locking screw is a necessary convenience feature that locks the calipers jaws and slider in place so that the parts do not move or slip as you take the measurements.

Without it, you might have a difficult time taking accurate measurements because the jaws will move slightly as you take the caliper out of the object, causing the readings to change a bit.

#5. Display

Different calipers are equipped with differently-sized LCD screens and the larger it is, the easier it will be to view the displayed readings.

Also, for the highest accuracy, ensure that the caliper displays a big number of decimal places in what is otherwise known as the resolution. Basically, the lower the resolution (more decimal places), the better.

#6. Ease of Use

Smooth jaw movements and highly sensitive machined thumb wheels are just but a few features that make any digital caliper easy to use.

Other desirable features that you should look for include a large display (as described above) and clearly marked push buttons for easy operation.

#7. Water Resistance

Some digital calipers have an IP54 rating, which basically means that they are resistant to dust and water sprays. Even though such units may be more expensive, this is a good feature to have because it raises the durability factor.

Tips to Use Digital Caliper

This product is very easy to use, but if you don’t follow the right steps, then you can get a lot of inaccuracies in the measurement process. To avoid this, use the tips below.

  • Ensure that you start from zero every time. Also, check the calibration before use. Most units come with calibration rods from the manufacturer and you should use this before use to make sure the caliper is well set.
  • Clean the jaws of the digital caliper as well as both sides of the object being measured to avoid inaccuracies brought about by dirt particles. This is especially important if you want an extremely high degree of accuracy, such as to the thousandths of an inch
  • Don’t over tighten the caliper. Proper contact is made once you feel a slight resistance if you try to pull the caliper’s contact pads across the object’s surface. Overtightening will slightly compress the object and this may alter its size measurements.
  • Whether you are measuring the outside, inside or depth, position the caliper’s jaws or depth gauge perpendicular to the object.

Conclusion 

There is quite a lot about digital calipers than what meets the eye. For this reason, it is important to be well informed about the different features that these products have before purchasing one.

This article is very resourceful and it explains all these features. After reading through, you should have a much easier time picking the best digital caliper that suits your needs.
