One activity that is often done throughout life is measuring an object. Want in terms of length, width, to height, these measurements are carried out to get one specific goal. The gauges are also different. For the most common measuring devices there are rulers and gauges.

But unfortunately, in these measurements, there are just measurement errors that can occur. This error also occurs due to various factors, in terms of humans who measure, defects in the tools used, to calibration errors. What is a calibration error?

Calibration error is an error caused by incorrect grading of the scale when making or performing calibration (standardization). With this error, it can appear an error in reading the measurement results, can be bigger or smaller than they should. In addition to the calibration errors that are included in the systematic errors section, there are also two other major errors namely general errors and random errors.

Each factor of this measurement error has a striking difference and is easy to determine its mention. To get to know more about this, here are three common measurement errors.

Common Mistakes

The first mistake that is part of the calibration error is a common mistake. Basically, common mistakes are mistakes that occur because of the limitations of the human factor when taking measurements.

For a more complete explanation, common mistakes occur due to errors in small-scale reading and lack of skills when using these measuring devices. With conditions, you can say the general error is the most common mistake made when taking measurements. To correct this error, the human being taking the measurement must be more careful than before. From how to use the tool, see the size of the tool, to see the measurement results through the tool.

Random Error

Random errors are errors that arise because of the creation of subtle fluctuations when making measurements. The subtle fluctuations referred to here consist of a number of reasons, such as electrical voltage fluctuations, the groundwork when making measurements that actually vibrate, noise, to radiation, and the brown air molecules.

As the name implies, random errors do not always arise consistently. In just a few moments this error will appear, and including errors that rarely arise, compared with other error factors. But it still is a pretty annoying mistake because it certainly makes measurements incorrect. In order not to be hit by random errors, it is best to pay close attention to the measurement process, not only in terms of the tools used, but also the surrounding environment, because it greatly influences the measurement process and the measurement results themselves.

Calibration Error

In accordance with what has been mentioned above, calibration error is an error caused by incorrect grading of the scale when making or performing calibration (standardization). Basically, calibration errors are included in a separate type of error, namely systematic errors.

Systematic errors themselves are errors that arise because the tools used are not supportive. In addition, the environment around the device being used can also produce systematic errors. There are various types of systematic errors, such as tool component errors, zero point errors, tool damage, parallax errors, humidity, extreme temperature changes, to calibration errors too.

But take it easy. Calibration errors can still be overcome. To overcome this error, the device just needs to be reset according to the standard (calibration) so that it can be used normally, and the measurement results can be precise.

That is an explanation of the various types of errors that can occur, especially calibration errors that turn out to often occur when making measurements. Avoid the mistakes above so that the measurement results can be more precise. Prepare the right measurement tool, check the environment around the measurement site so that it can carry out the process properly, and as a human being, take measurements carefully. Even if there are errors that occur, immediately find a way out in order to get the right measurement results and do not bring new problems again for you.
