How Does A Digital Protractor Work?
Despite being a more modern form of an older tool, digital protractors are actually incredibly easy to use. In the simplest sense, a digital protractor is an angle gauge that effectively measures angles to a very precise degree.
It does so by connecting two separate rulers at a pivot point, and then measuring the angle that is created when they are in different positions. There are a number of different applications for this type of measurement, but the most common method of measuring angles with a digital protractor are vertical and horizontal.
Vertical measurement is performed by placing one end flat on the ground surface and angling the other end upwards. You can probably guess how the horizontal method works and is typically used for determining the inside angle of small objects.
How to Use a Digital Protractor
Using a digital protractor is very easy thanks to its digital display and the lack of assembly that is required. You should first start out by analyzing the object or surface that you need to measure.
If the angle can be laid flat on a surface, you can simply lay the protractor directly on top of it and align the rulers with the object that you are measuring.
If you are trying to do something like stand a beam in a perfectly straight position, all you have to do is set the ruler side flat down with the secondary end sticking straight up.
Finding the correct measurement is easier than ever with digital protractors. Their digital displays allow for a much more precise measurement, and many can offer increments to the nearest tenth of a degree.
If you are familiar with how to use a standard protractor you will probably have no problem at all figuring out how to use it modern digital counterpart. You will have to secure the pivot point down and be sure to consider whether it would be easier to measure the angle vertically or horizontally.
Things You Should Consider When Buying a Digital Protractor
Whether you are a constructor, woodworker or doing simple maintenance at home, a protractor is a must-have tool that you should have in your tool box. It is used for everything from cutting angles to wood joints.
Digital angle finders are divided into two categories, professional and amateur. If you are going to use the instrument a couple of times, there is nothing wrong with selecting the amateur type. If you are a professional, it will be best to consider the professional section.
Most modern protractors come in standard style and have digital gauges for accuracy. Others come in form of a small cube or box. Although the style does not affect accuracy, the brand and technology will definitely have an impact on how well the protractor works.
A measurement error can radically increase costs of your projects and that is why you require a digital angle finder. With the examples stated above, you can quickly select the easiest model for your exact usage.
Below are some of the major factors you should look into when selecting a digital protractor
Accuracy
This is the most important feature that will enable you take measurements without errors. If you are looking for specific angle measurement, it is best to select a digital angle finder. They are very accurate within a tenth of a degree. You may not be lucky with the manual protractors.
Whether or not you are having problems finding angles depend on the tool you are using. Some allow you to calibrate the angle finder depending on the surface it is sitting on while others may not. If you value accuracy above any other metrics, select an instrument that will make your calculations simpler.
Wide Measurement Range
A digital protractor is capable of measuring angles between 0-360. This gives the instrument versatility when dealing with many different kinds of projects. Using a manual finder can be exhausting and difficult for the extreme angles, something that a digital one does in seconds. One of the main useful functions of the instrument is versatility.
Level Included
It is imperative to check if a level is included in your digital protractor. This is a convenient feature which saves you from going back and forth between your level and finder with each single cut. It is a good insurance policy just in case you forget your own level.
Any instrument that fulfills more than a given task prevents you from carrying many other tools. These are the sort of things that make the difference when working on a project.
Quality
Investing wisely in your project is all about the quality you buy. The instruments available in the market are all made of different materials. There are those that are durable while others are not. For example, you would expect stainless steel instruments to last for long, which may cost you more as compared to light plastic.
Added In-Built Measurement Features
There are those that come with just one function. However, best angle finders come with features that make work easier. Among the added feature is a cut calculator. It ensures that each piece you cut fits in the exact manner you want it to. It will be more tiresome to find that the cut you made is off by an inch.
The cut calculator does the work for you ensuring every piece fits. Other instruments have Bluetooth technology to enable you back up data on your phone or other mobile device. With it you can carry around work data with ease.
These added features increase the price of the instrument. If you do not need them, going for such a tool may be a waste of money. Alternatively, if you require these features, buying a digital protractor that only perform its core function will cost you more as you will have to buy additional instruments.
Price
Digital protractors are comparably more expensive than the manual types. You however should keep in mind that you pay for what you get. If you are doing a one-time project, look for a pocket friendly type but if not, invest well to get one that will last.
How you plan to use your angle finder will determine the one you select. If you are into woodwork, a versatile tool will probably be a god choice. If you are into construction, a compact type will be a good choice to fit within any nook and cranny.
