A power supply is a critical part of a particular measurement instrument. Almost all parts of a particular measurement instrument require electricity to run. The power supply in this case provides electricity to energize the system right from the transducer (sensor); we mean the passive one, goes to the microcontroller, and all the way down … Read more
Almost every single human in the world carries a display that is embedded into such a device called a cellphone or smartphone at this very moment. However, we might have no idea what type of display that is and how the mechanism works behind it. In this article, we are trying to bring the best … Read more
The reliability of handheld tools like calipers is frequently required in many areas that need higher accuracy and precision such as in engineering, metrology, manufacturing, quality control, 3D printing, etc. However, behind its advantage, these measuring tools are important to keep them well maintained to give accurate readings with extended life. The care includes regular … Read more
In engineering, the requirement to know what to measure on a day-to-day basis is essential. You have to know what to check for all shapes, sizes, and axes, including spherical or cylindrical. While doing those jobs, it means you are going to measure runout and total runout. It is usually noted for parts or components … Read more
Maybe, you are planning to buy an oscilloscope but the logic analyzer also seems to suit your need. Due to budget, you only have one choice to choose from. All you have to do is to learn both of them first so that you know which one is really appropriate for your project. Aside from … Read more
As highlighted above in the article, an oscilloscope measures signals in the time domain while a spectrum analyzer captures and measures signals in the frequency domain. In the previous article, we have discussed the differences between oscilloscopes and logic analyzers. In this post, we are going to differentiate another electronic testing instrument spectrum analyzer from … Read more
Maybe, you are searching for an electrical measuring device that can measure the current. You know they are either multimeter or clamp meter. But, you are not sure which one to choose from. Because getting a little confused about how one differs from another, you start to dig more information about how they contrast to … Read more
LCR meter and multimeter are one of the most if not the most important measuring instruments for an electrical engineer. A Multimeter is often the first choice for a hobbyist or a student getting into the industry. Further, with an advanced understanding of the fundamental concepts, instruments such as an LCR meter might come in … Read more
There are multiple reasons for errors that may happen while using a caliper be it the vernier, dial, and digital model. The sources of error may be generated by the faults in the instrument, human error in the method of calculation, environmental factors, etc. These errors, further, can affect negatively the measurement results; though some … Read more
Electromagnetic field meters, often known as EMF meters, are commonly used in businesses and residences to monitor non-ionizing radiation. An EMF meter is able to measure electric field, magnetic field, and radiofrequency field. On the other hand, there is another device to measure only the magnetic field which is the Gauss magnetometer or Gauss meter. … Read more
