Multimeters and voltmeters may seem the same to any other person but to an electrician or electrical engineer. These two measuring devices are different in many ways. But as their names suggest, a voltmeter measures only voltage. On the other hand, a multimeter can measure more than one electrical parameter, including voltage, current, resistance, capacitance, … Read more
How to know that your protractor is accurate? What is the way to assess that your protractor’s accuracy is still within the permissible accuracy (tolerance)? What if your protractor actually needs a replacement? All of these questions can be answered with a protractor calibration. This article will provide a basic idea of the techniques for calibrating … Read more
When it comes to ruler calibration, we are talking about the accuracy of its graduation. Ruler is a linear measuring hand tool we use in broad areas such as school, office, workshop, manufacturing, etc. It’s not only for measuring length but also for marking and scribing lines. Depending on the purpose of using the ruler, … Read more
You may be hiking and seeing the altitude reading on your altimeter device. But somehow, the term elevation pops up in your mind, and you realize that they are almost the same and do not know how to distinguish them. If you are wondering what actually altitude and elevation mean, then this page may help … Read more
Wondering how roundness and circularity are different? Or both are actually the same? How to express them in terms of tolerance? We’ll be discussing it here. Roundness In simple words, the term roundness is defined as a value that is used to compute the errors that appear in a perfect circle. In other words, roundness … Read more
When it comes to the axis of a circular or cylindrical object, you will find these two terms “coaxiality” and “concentricity”. If you are an engineer, you denenitely have to know about them. For those who are looking to find how they differ, this post may help you a little bit Coaxiality The coaxiality is … Read more
If you want to check whether a surface state is level or not, you can use a spirit level; the same tool is also capable to check for plumb. But spirit level is not the only tool to check levelness. There are digital levels and laser levels as well. Confusingly, either of these models has … Read more
In construction, a spirit level is a necessary tool that is used to determine whether a surface is level or not. It can also be used to determine whether something is plumb or not. Among the types of spirit levels, the I-Beam and Box Beam are the two similar models that are interesting to talk about. … Read more
When buying a tape measure, it’s important to consider what class of tape measure is suitable for your project. The difference in class among various tape measures accounts for the difference in their respective accuracy. To be clear, this classification of each tape measure primarily depends on their ability to follow the standards of accuracy … Read more
Are you building a flat and level desk for your project? Do you need a flat floor but have a little slope on it? Or need a flat floor with a perfect level? Do you want to build a kitchen cabinet that is flat and level? The two terms flat and level are considered the … Read more
