If the measuring errors are not compensated for, the underpower
setting should not be lower than the sum of the current-measuring and
voltage-measuring errors.
For example, if the error of the current-measuring device is 2% and
that of the voltage-measuring device is 1%, the minimum setting is (2
+ 1)% = 3%.
