What does calibration mean? Easily explained
You have probably come across the term "calibration" in connection with technical devices. In this practical tip, we explain what this means and in which situations calibrating can be helpful.
What is the term "calibration"?
Calibrating generally means setting devices or software more precisely. A measuring device is often set up to an initial value. For this purpose, a measurement is carried out in order to recognize and document the deviation from the correct value. Then it makes sense to readjust the device until the measured values are again within the tolerance range. In short, calibration teaches the device default values and makes operations more accurate.
Calibrate: what is it in everyday situations?
Many technical devices have to be calibrated at regular intervals. This is especially true for devices that have to communicate official measurement results. But there are also some applications in private use:
- Calibrating the monitor of a PC is common practice. This is especially necessary when you edit and print digital images. This way you can ensure that the colors and contrast are displayed correctly. You can also calibrate your screen yourself using on-board equipment.
- If you have connected a gamepad to your computer, you usually have to calibrate it first. This allows you to define the key assignment and the response speed of the analog stick, among other things.
- Especially on tablets, PCs with touchscreen and smartphones, the touchscreen is often calibrated when used frequently. This ensures that the screen reacts to your touch exactly as it did at the beginning.
- The battery can also be calibrated, for example with smartphones using various apps. Then the battery level is recorded more precisely.
- Motion sensors also require calibration after some time. This will return you to the initial state and movements can be recorded more precisely again.
