Communication is an activity that everyone does daily. To communicate is to send (transmit) or receive the data (information) between two or more sides. In the electronic world, communication is done in certain ways. The protocol regulates it. A protocol consists of a set of rules that ensure a secure and reliable communication process. In … Read more
Calibration is to find out the measurement error. According to the measurement error 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 [Source: International Vocabulary … Read more
Gauge blocks or slip gauges or Jo-blocks are used for calibration, inspection, and verification. They function as standards. According to its grade level, they can be a reference or working standard. Therefore, you could find gauge blocks in the area of the workshop and calibration lab. The role of gauge blocks is highly vital in … Read more
You may wonder about the differences between the gauge and instrument. Both of them we use in many times and many places. In this post, we will briefly break down their differences. 1. Gauge A gauge comes in a fixed dimension which has only a single readout. For example, a single feeler gauge comes in … Read more
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 question might arise from you when trying to determine what is actually controlling the daily appliances you often meet, such as a printer, microwave, or even a simple line-following robot. Well, the answer you have been seeking is right here in this article. The thing that controls those devices called a microcontroller. By reading this … Read more
We do agree that almost every aspect of our life is processed by the digital processing system. It’s the reality that most of us already at least have a laptop, PC, or smartphone. However, the world we are living in at the moment is the analog world. It is logical that the data conversion from … Read more
A transducer is an electronic device that functions to convert the energy from a certain form into another form. The process to convert the energy from one form into another is called transduction. The conversion is going through two processes, which are sensing and transducing the physical quantity (units) such as length, pressure, temperature, sound, … Read more
Repeatability in measurement is a vital aspect when it comes to precision in measurement. Along with reproducibility, you get two aspects of precision to analyze. They show how consistent a repeated measurement is. As a result, it generates a reliable measurement. Learning about measurement repeatability is not only important in the field of metrology but … Read more
