Calibration is an essential service for all measurement technology. For every industry, measurements need to be accurate, and they need to fit an agreed-upon standard. Getting accurate measurements from a device like a multimeter is essential to its purpose. A technician would have a hard time avoiding needless mistakes if they were getting incorrect readings on voltage or resistance.
Calibration also serves to provide guidelines for repairing an instrument that is out of calibration. Proper calibration will expose how an instrument's measurement is off. Having the service of a calibration lab is a must when it's time to fix instruments that have measurement errors.
During calibration, we use a calibrator to take a measurement. These devices are measurement tools that are used to give a known, accurate reference. Next, we take the exact measurement with the device that is set to be calibrated. We call these the devices under test. This side-by-side comparison allows us to check the accuracy of the device under test against the calibration standard.
Electrical calibration involves making measurements and adjustments on different measurement modes of a multimeter or other device for measurement. The most common modes of measurement are alternating current/direct current (AC/DC) voltage, current, and DC resistance measurements. And also frequency, harmonic waves, power factor, phase angle, and active/inactive/apparent power/energy are needed in some areas.
These programmable instruments are designed for precision, performance, and functionality, making them ideal for automatic testing and fault For manufacturing applications they can be used for signal injection and measurement tasks where stability and accuracy are critical.
