Avoltmeter with a range of 0 to 100 v reads 2 v when the leads are shorted together. the manufacturer claims an accuracy of ±4% of full scale. estimate the maximum error when reading a voltage of 80 v in both volts and as a percentage of reading. if the voltmeter is adjusted so that the reading when the leads are shorted together is 0 v, estimate the maximum percent error when reading 80 v.
