Q. Error speci?cations on a 10-A digital ammeter are given as 0.07% of the reading, 0.05% of full scale, 0.005% of the reading per degree Celsius, and 0.002% of full scale per degree Celsius. The 10-A analog meter error speci?cation is given as 0.5% of full scale and 0.001% of the reading per degree Celsius. If the temperature at the time of measurement is 20°C above ambient, compare the percent error of both meters when measuring a current of 5 A.
