Sähkökalibrointilähte

Sähkökalibrointilähte translates to electrical calibration source in English. It is a device used to provide precisely controlled and known electrical signals for the purpose of calibrating measuring instruments. These instruments, such as multimeters, oscilloscopes, power meters, and signal generators, need to be regularly checked and adjusted to ensure their accuracy and reliability.

A sähkökalibrointilähde generates specific voltage, current, resistance, or frequency values with a high degree of certainty. The accuracy of the output is typically traceable to national or international standards. This traceability is crucial for ensuring that measurements made with the calibrated instrument are consistent and comparable across different locations and over time.

These calibration sources are essential in various industries, including manufacturing, research and development, telecommunications, and metrology laboratories. They are used to verify that instruments are within their specified tolerances. If an instrument deviates from its specified accuracy, the calibration source is used to adjust it back into compliance.

There are different types of electrical calibration sources, ranging from simple DC voltage and current sources to highly complex, multi-function calibrators capable of generating a wide array of AC and DC signals, as well as specialized waveforms. The choice of calibration source depends on the type of instrument being calibrated and the required level of accuracy. Maintaining accurate calibration is fundamental to quality control and scientific integrity.
