The extent to which the value indicated by a measurement system or element might be wrong. summation of all the possible errors that are likely to occur, as well as the accuracy to which the system or element has been calibrated. Accuracy is often expressed as a percentage of the full range output or full-scale deflection (f.s.d). Each point 1 mark Max 2 mark
