Digital scales aren’t really the most accurate type of scales out there, so calibration is extremely important. These things, and other electronic products such as WiFi or bluetooth technology, can cause interference and potentially affect your readings. Calibration of a weighing scale is key to getting an accurate reading. If the indicated weight differs from the known weight, calibration entails adding or subtracting the weight difference.
