Measuring interval
The set of values of quantities of the same kind that can be measured by a given instrument or system with specified instrumental uncertainty under defined conditions — the interval the specifications actually promise.
VIM (JCGM 200:2012) 4.7
Discrimination threshold
The largest change in the value of the quantity being measured that causes no detectable change in the corresponding indication — stickiness quantified.
VIM (JCGM 200:2012) 4.16
Step response time
The duration between the instant an input quantity is subjected to an abrupt change between two specified constant values and the instant the indication settles within specified limits of its final steady value.
VIM (JCGM 200:2012) 4.23
Resolution
The smallest change in the quantity being measured that causes a perceptible change in the corresponding indication. Digital resolution contributes a rectangular uncertainty component of (δ/2)/√3.
VIM (JCGM 200:2012) 4.14
Sensitivity of a measuring system
The quotient of the change in an indication and the corresponding change in the value of the quantity being measured.
VIM (JCGM 200:2012) 4.12
Selectivity of a measuring system
The property whereby the system provides measured values for one or more measurands that are independent of other measurands or influence quantities.
