Shinta When it comes to precision measurement tools and devices such as mechanical micrometer, caliper, indicator, etc, we take the reading in inch reading. You need to know the inch reading is actually an imperial unit system. Here we are going to briefly discuss imperial unit system including its history, the units, and countries that keep … Read more
Micrometer’s least count means the smallest increment figure that the micrometer’s scale provides. It’s also the smallest thickness or length that can be measured. For example 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, these row of numbers has 1 increment figure. Another example, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, … Read more
In short, the idea behind how micrometers work is a combination of these two: the working principle of the differential screw and the distance magnifying that is affected by the thimble diameter. In this page, we only explain the micrometer working principle of the mechanic type one. Differential Screw According to Wikipedia, “A differential screw … Read more
Zeroing in micrometer is the process of adjusting the index line to line up straightly mark “0” of the thimble scale when the measuring faces of the micrometer are closed properly. In basic terms, it’s a way in order for the measuring tool to get repaired its zero error. How to zero a micrometer is … Read more
Using a tape measure is basically easy. Things that you need to consider are the hook and the tape. On this page, we are going to discuss how to use the hook and read the tape. If you know how to use it and read the marks properly, that’s good, whereas if you are still … Read more
When talking about how laser measure works, the first thing that you have to learn is the laser itself. This is the physics artificial phenomenon that takes a big chunk of the portion on how the laser measure works. Other aspects to know are some basic math and light speed coefficient. As the laser measures … Read more
The word micrometer itself is a combination of two Greek words. These words are “micros and “metron”, the meaning of micros is small and the meaning of metron is measure, both of them combine to give micrometer its name. William Gascoigne was an astronomer who first invented a micrometric screw while measuring the star in … Read more
One of the reasons why you should choose tape measures as your length measuring tool is their easy-to-maintain advantage while it provides great functions that you can’t obtain from an ordinary length measuring tool. Even though easy, if you don’t take care of it properly, it will break apart early. Here are some simple tips … Read more
A tape measure is actually a long ruler that can be bent and rolled-up so that we can get it housed in a case then pick it anywhere. It is a problem solver when we need a portable long-range ruler. That’s why carpenters, builders, etc are those who always pick tape measures for their measurement needs. … Read more
Calibration is to find out the measurement error. According to the measurement error that is observed, verification is to decide whether it is within the tolerance (permissible error) or not. Then, validation is to make sure it measures what it’s meant to. In some cases, verification and validation overlap. Calibration According to NIST, calibration is … Read more
