SUMMARY
The discussion centers on calculating the relative error of a voltmeter measurement of 50V with a maximum input voltage of 300V. The correct relative error is determined to be +/- 0.8%, factoring in both absolute voltage error and percentage of full scale error. The absolute error is 0.1V, and the percentage of full scale error is 0.1%, leading to a total error of +/- 0.4V. The initial calculation of 0.0016% was incorrect due to misunderstanding the error components involved.
