zeroadjust
zeroadjust is a term that can refer to several related concepts, primarily within the fields of measurement and calibration. In its most general sense, it describes the act of setting an instrument to a zero reading when it is not subjected to any input or stimulus. This is a crucial step in ensuring accurate measurements, as any deviation from zero in the absence of a signal can lead to systematic errors in subsequent readings.
For example, in a digital scale, zeroadjust would involve pressing a button to make the display read
The specific implementation of zeroadjust can vary depending on the device. It might be a manual button
