Fullskalevärdet

Fullskalevärdet, often translated as "full-scale value" or "full-scale reading," is a term used in measurement and instrumentation. It refers to the maximum value that a measuring instrument can display or record within its specified range. For example, a voltmeter with a full-scale value of 10 volts can accurately measure voltages up to 10 volts. Readings above this value would exceed the instrument's capability and likely result in an inaccurate or undefined output, sometimes indicated by an "over-range" signal.

Understanding the fullskalevärdet is crucial for selecting the appropriate instrument for a given measurement task. Using an instrument with a fullskalevärdet that is too low for the expected measurement can lead to saturation and loss of information. Conversely, an instrument with a fullskalevärdet that is much higher than necessary might offer lower resolution for the actual measurements being taken, making it harder to discern small changes. It is a fundamental parameter that defines the upper limit of an instrument's operational range and is directly related to its accuracy and precision.
