Comment 10 for bug 230850

Maybe you also want to know why I applied that correction:
it also affects the limit-settins. If 5 volts nominal is reported as only 4.8 volts it is already cose to the lower (warning) limit of -5%, in volts 4.75 and may cause invalid warnings.
The second formula after the colon in the same line is for the reverse calculation only.
