How to Use Mitutoyo Calipers

Electronic calipers, digital calipers, were created to replace conventional rulers, making measurement accurate and more efficient. Along with the development of technology, there are many brands of measuring devices that produce quality and competitive products, Mitutoyo measuring instruments is one of the brands that are trusted and used by many people. Thanks to its accuracy and design advantages.

As one of the measuring devices used in many measurement jobs, the Mitutoyo calipers are highly appreciated for their accuracy and price. However, to use the product so effectively and accurately, nobody knows. The article provides a way to use the Mitutoyo calipers or digital calipers that you may need. A digital vernier caliper is a versatile tool (measuring external dimensions, internal dimensions, depth measurements) with a wide range of sizes, relatively high accuracy, ease of use, low cost, etc.

There are many types of calipers, such as:

* Calipers: Display measurement results on an analog clock face.

* Digital calipers: Display measurement results on the electronic clock face.

* Mechanical calipers: Display results on the mechanical scale.

Here we introduce the best way to measure and store Mitutoyo electronic calipers or digital calipers:

Preparation

  • Step 1: Dry and clean the measuring surface of the object that you will measure with a clean cloth (or soak with oil cleaning).
  • Step 2: Loosen the locking screws of the electronic caliper
  • Step 3: Dry and clean the lower right and left clamping jaws of the digital caliper with a clean cloth (or soak with cleaning oil).
  • Step 4: Dry and clean the upper and left clamping jaws of the electronic caliper with a clean cloth (or soak with cleaning oil)
  • Step 5: Slide the clamping function of the digital caliper fully closed and then press the ON button. If the reading is 0, then you can take the measurement. If the number on the dial is still not displayed as 0, then you need to clean the jaw until there is no dirt affecting the size.
  • Step 6: Move the slider to check if the LCD screen and all the buttons on the electronic calipers perform well

Start measuring:

When you play the measurement, do not touch the measuring surface of the object being measured and the measuring surface of the electronic scale with your hand as it may lead to inaccuracy due to sweat on your hands. You need to keep them clean during the measurement.

Before measuring objects, first of all, you need to press ON to start the digital calipers

1. Measure the electric calipers:

  • Step 1: Place the lower clamping function of the digital calipers on the outer parts of the product.
  • Step 2: Slide gently until both of the lower jaws are tightened against the outside surface of the product.
  • Step 3: Then read the number directly from the large LCD screen. As such, external measurements are made quickly.

2. Size inside the electronic calipers:

The method of taking internal measurements is similar to measuring from the outside. However, internal measurements with only the upper jaw of the digital calipers can handle this.

  • Step 1: When measuring the inside diameter of the object, you first need to insert the upper jaw into the hole.
  • Step 2: Slide so that the jaw is open until it fits into the hole completely.
  • Step 3: Then read the number directly.

3. Measurement of electronic vernier calipers steps:

It is essential that when you measure the levels of the digital calipers on the product, the product must be on a hard and flat surface.

  • Step 1: Place the tip of the electronic vernier caliper on the plane and make sure that the measurement steps are perpendicular to the plane.
  • Step 2: Clearly, the result will be displayed on the screen, which is the result of measuring the levels of the digital calipers.

4. Depth measurement of a digital caliper:

  • Step 1: Move the meter slider bar to insert the gauge depth into the object to be measured.

Note: the square should be placed with the inside of the object to be measured.

  • Step 2: Move the slider slightly until touching the fixed surface of the product.
  • Step 3: After that, read the results displayed directly on the LCD.

Instructions for maintenance and storage of electronic calipers or digital calipers

  • Never apply a voltage (such as etching a pen) on any part of the Mitutoyo digital calipers for fear of damaging the circuit.
  • Press ON / OFF to turn off the power when the caliper is not in use, remove the battery from the machine if the machine is not used for a long time.
  • For battery, if the display is not standard (digits flashing or not even displayed) shows that the battery is low. So you have to push the battery cover as the directional arrow and then replace it with a new one. Battery discharge action…) please contact the supplier.
  • In case of water entering the battery cover, open the lid immediately and blow into the battery cover at a temperature not exceeding 40 ° C until it is dry.

In conclusion

The digital calipers, or vernier calipers, are a relatively accurate measuring instrument, used a lot and mainly in the mechanical engineering industry, plastic, wood, or aluminum and glass… For a professional engineer mechanics, the use and read the calipers that it is intuitive, but for many students due to the actual contact conditions or challenging access environment, inevitably, they do not understand in-depth on how to use an electronic caliper. Through this article, in addition to choosing for yourself the best digital caliper, I hope it will help you in your work as well as learn about its use and maintenance.

How to prune large trees

Your family has some pretty big trees.  You find that its branches are too large to take up all the other plants in your garden. Or you feel uncomfortable when their branches touch the roof of your home and make loud noises that keep you up at night. To solve this problem, you plan to hire a worker to cut the branches but when you know the price of their cutting, you have to give up. Does your house have the best pruning saw? Why don’t you cut the branches you want with it? Pruning saws are a commonly used tool. I’m sure you all have seen them somewhere already. It supports you to trim branches especially large branches efficiently and easily. However, using and cutting properly is not well known. If you are new, you will face even more challenges.

Understanding your concerns, in this article, I will show how to cut large trees easily and efficiently. If you’re just a beginner, you can easily do that. Are you curious? I don’t take much of your time anymore. Let’s start exploring.

Time suitable for pruning

Winter is the best season for tree pruning work (late winter is best). Why? Because as you know, winter is the time of deciduous trees. You can see the bad branches or touch your house. And in particular, when you’re done cutting. Then the season will come, the leaves and flowers will sprout and grow quickly, which will not accentuate your cut and lose the aesthetics of the tree.

How to pruning

Step 1: Locate the dead and bad branches that you want to cut. Locating dead branches is quite simple. On the outside, it will have a completely different color from the other branches. Moreover, in that branch, leaves or buds cannot grow. Besides, according to experts, the U-shaped limbs on the branches are healthy and should remain on the tree. You should only remove limbs with V-shaped branches.

Step 2: You start with the first cut. You use a pruning saw to cut from the underside of the branches upwards. The pruning saw is quite outstanding, ensuring that you can cut up to 18 inches deep easily and effortlessly. You should also note that for safety, you should wear some protective equipment such as gloves, glasses, … Moreover, If you are trimming on high branches, you need to use a ladder or zipper to ensure safety

Step 3: After the first cut, it’s time for your second cut. Make a second cut slightly further on the branch from the first cut. This time, you cut across the branch from above. Before making the final cut, you need to determine the position of the branch collar that is usually at the end of the branch that is close to the trunk. Be careful when trimming just outside the branch collar. Because, if not a little careful, you can mistakenly cut into other important parts of the nearby tree. Moreover, if the collar of the branch is intact after pruning, the cut will be more effectively sealed and the stem tissue may not decay.

Step 4: After cutting the branches at the top. Now it’s time for you to cut the branches under the tree where you have difficulty walking. Continue using the pruning saw to cut them.

Step 5: Note: You need to be aware that cleaning your saw with a dedicated disinfectant after you prune each tree to help prevent the spread of disease from tree to tree. That helps your saw to be used longer without rust and damage.

The specific steps are as follows:

First, you need to pour a small portion of the bleach solution into the water (remember to mix well). Then rub the mixture on the saw blade and let it stand for a few minutes. Follow that with a dishwashing detergent mixture and water. Finally, you need to clean the blade with clean water and wipe dry completely with a clean towel.

Common mistakes when pruning trees

Cut branches too short: Many gardeners have a habit of cutting branches to the stem of the tree. That should not be. As you know, the collar is responsible for forming scar tissue for the tree. This means it helps the tree grow and recover after each pruning. If you cut into the branch collar, the tree will take a long time to recover. When you see rotten holes in a tree trunk or ugly wounds that ruin the aesthetics of a tree, you will know how serious the consequences of a collar cut will be.

Impact of old branches: As I said above, the branch collar is supposed to help heal the cut. Of course, it only works on the branches that it covers and preserves it. Therefore, if a branch of your house is having problems like the first one is to cut off the collar. It will affect the restoration and healing of nearby branches. Therefore, you must be especially careful when cutting.

Failure to cut relief: If you do not make relief cuts and remove most of the weight of the limb before cutting branches near the trunk, your branches are at risk of splitting. This can make the wound on the trunk more susceptible to disease. And easily destroyed by insects. In particular, they will take longer to heal.

In conclusion

I have finished showing about how to trim a large branch and some common mistakes when cutting. Have you found the above information helpful to you? I hope they are useful and necessary for you.

Final notes I want to remind you. You should only cut about 25 percent of the branches per year. That helps the tree to balance. Besides, you should limit pruning of the upper branches because it is not only dangerous for the cutter but also worsens the aesthetic of the tree. Ultimately, thank you for taking the time to read through this article.
