Things to know about the best digital caliper

Technology is growing, and measuring devices are also increasing day by day to bring about the best efficiency, serving the needs of people. One of the most commonly used measuring instruments today is digital caliper. This caliper is known for its high accuracy and is also easy to use. In this article, I will show you more specific information about these types of calipers as well as guide you on how to apply, preserve it in the best way, to bring the highest efficiency.

What is a digital caliper or electronic vernier caliper?

An electronic caliper is a measuring tool used in many manufacturing industries such as mechanics, woodwork, plastic, aluminum, and glass, etc.

This tool is used to measure dimensions such as the length and width of a cylindrical or square part or measure the inner diameter, outside diameter, and depth of objects.

Digital calipers, also are known as electronic calipers; the accuracy of this measuring instrument is considered to be relatively high.

Characteristics

  • The digital calipers can measure the outer dimensions, internal dimensions, and depth of objects.
  • The measuring range of the vernier scale is quite broad, and the accuracy is relatively high.
  • The price of the calipers is relatively low and sold on the market.
  • The electronic vernier caliper is easily usable due to its reasonably simple usage.

Structure

structure

The structure of a digital caliper consists of the following parts:

  • External measuring face
  • Internal measurement surface
  • Level measurement surface
  • Screw brakes
  • LCD screen
  • Depth gauge
  • Main measure
  • Body size
  • Battery compartment
  • Point setting button 0
  • The power button is off
  • The switch for units in inches and meters
  • Original zero setting button “0.”
  • Roller
  • Cable connection port

User manual

1. Prepare to measure

For the object to be measured: dry and clean the surface of the object to be measured.

For electronic caliper:

  • Loosen locking screws of the caliper.
  • Jaws clamping of the digital calipers include in jaws clamping on the right, clamping jaws on the left; the lower right maxilla, the lower-left mandible of the caliper should be dry and clean.
  • Next, slide the clamping jaw of the calipers fully closed, then press the ON button to clamp.
  • Clean the clamping function until the meter shows 0; if the meter shows 0, then measurement can be made.
  • Check the LCD screen and all the buttons on the caliper by moving the slider.

2. Proceed to measurement

  • For external dimensions:

Step 1: Place the lower jaw of the calipers on the outside of the object to be measured.

Step 2: Perform a slight sliding so that both of the lower clamping jaws grip the outer surface of the object to be measured.

Step 3: Read the measurement results shown on the LCD screen. The number displayed on the screen is the size of the object to be measured.

  • For measuring internal dimensions: it is performed in the same way as measuring external dimensions; however, the clamping jaw is used only with the upper jaw of the ruler.

Step 1: First, insert the upper jaw into the inside of the object to be measured.

Step 2: Make sliding so that the clamping jaw is opened until it entirely fits inside of the object to be measured.

Step 3: Read the number displayed on the screen. This number is the size of the object to be measured.

  • For step measurement:

Step 1: Place the object to be measured on a hard and flat surface.

Step 2: Proceed to place the tip of the calipers on the plane. When laying, ensure that the measurement steps are perpendicular to the plane.

Step 3: The measurement result is the number displayed on the screen, read this number, and we will get the size of the object to be measured.

  • For depth measurements:

Step 1: Move the ruler slider to bring the depth gauge to the object to be measured. Must be perpendicular to the inside of the purpose to be measured.

Step 2: Proceed to move the slider gently until it touches the fixed surface of the object to be measured.

Step 3: The measurement result is the number displayed on the screen, read this number, and we will get the size of the object to be measured.

Caution when preserving and using digital calipers

1.Preservation

  • Do not place the electronic caliper in water or allow other liquids to spill on the caliper.
  • Do not make incisions or substantial impacts on the caliper.
  • Keep the digital caliper carefully, do not let the caliper fall from above, avoid the ruler from being hit and may damage or affect the measurement results.
  • Do not expose the ruler to direct sunlight.

2. Note when using

  • When you are finished using it, press OFF to turn off the power.
  • Remove the battery from the device if not in use for a long time.
  • If the screen has abnormal displays, then you need to check the battery. If the battery runs out, replace the battery. If the battery remains, proceed to clean the dirt on the ruler.
  • If the battery door is exposed to water, open it immediately and blow inwards at a temperature not exceeding 40 ° C until it dries.

In conclusion

In this article, I have provided you all the information about digital calipers as well as how to use them to get the most accurate results. Hopefully, this will help your work and study with regards to electronic calipers or digital calipers
