Quantity value provided by a measurement instrument or a measuring system.

Note 1: An indication may be presented in visual or acoustic form or may be transferred to another device. An indication is often given by the position of a pointer on the display for analog outputs, a displayed or printed number for digital outputs, a code pattern for code outputs, or an assigned quantity value for material measures.

Note 2: An indication and a corresponding value of the quantity being measured are not necessarily values of quantities of the same kind.

Note 3: In many analytical instruments, the detector response is converted into an indication being linearly related to the value of the quantity to be measured. Example: The indication provided by a spectrometer may be linearly related to the radiant power detected, or to transmittance, absorbance or absorption coefficient of a sample, or to the concentration of a specific analyte in the sample.
