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

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

Two things to get a better understanding of how the gauss meter works: Hall effect and Lorentz force. Gauss meter works making use of the Hall effect. The semiconductor of the Hall effect sensor is charged with current. The magnetic field will pull or push electrons in the semiconductor and then creating voltage differences. This … Read more

The first time using a micrometer, you may get a little stunning fuzzy because you don’t know what to start from. Can’t keep silent, you decide to try measuring. Stop it, please! You could ruin the micrometer’s accuracy because rotating the thimble too tight. Using a micrometer is actually easy. There are only some steps … Read more

After you learn how to use the micrometer, the next basic is how to read the micrometer or taking the reading. The unit system that’s used in micrometers has two versions. Therefore in this page, we cover how to read a micrometer in those two versions: metric (mm) and imperial (inch). Reading a micrometer is … Read more

Measurement traceability or the fancy term “metrological traceability” is an important element in relation to accuracy. Someone may claim they are accurate, however, without measurement traceability, it’s just a claim. If you are going to hire a calibration service for your measuring instruments, this is an interesting topic for you. You have to make sure … Read more

A micrometer is one of the linear measuring instruments, provides accuracy down to 1/100 of a millimeter. Even, some of them can reach 1µm accuracy. It’s truly a hand-held tool that you can rely on to measure something very thin or to get more detail about the thickness, length, diameter, and depth of an object. … Read more

An ADC (analog to digital converter) is an electronic circuit that converts the analog data (continuous) from nature into digital data (binary). The ADC circuits can be found as a stand-alone ADC IC module or embedded into microcontrollers. The following features are best for you to understand before you go deeper about ADC. ADC Features … 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
