Limiting error: The maximum allowable error in the measurement is specified in terms of true value, which is known as limiting error. It will give a range of errors. It is always with respect to the true value, so it is a variable error.
Guaranteed accuracy error: The allowable error in measurement is specified in terms of full-scale value is known as guaranteed accuracy error. It is a variable error seen by the instrument since it is with respect to full-scale value.
Calculation:
Full scale voltage = 200 V
Accuracy = 0.5%
Voltage to be measured = 50 V
The limiting error is given as:-
