2. A voltmeter 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.
