Delay time is the difference in time between the change of the component to be measured at the reference point and a system response of 10 % of the final reading (t 10) with the sampling probe being defined as the reference point.\n2.2. Response time is the difference in time between the change of the component to be measured at the reference point and a system response of 90 % of the final reading (t 90) with the sampling probe being defined as the reference point.\n2.3. Rise time is the difference in time the 10 % and 90 % response of the final reading (t 90 – t 10)\n2.4. Transformation time is the difference in time between the change of the component to be measured at the reference point and a system response of 50 % of the final reading (t 50) with the sampling probe being defined as the reference point\n2.5. Step input time is the time at which there is a change in the parameter being measured.\nFigure 6-11\nIllustration of system responses",
