"To measure low AC voltage, the signal must overcome the internal rectifier's forward voltage"
Paul, are you sure modern meters use a rectifier? I had just assumed an ADC would be used for this, with the lowest measurable signal equal to one bit. Of course, I haven't studied AC measurement techniques relating to instruments in years. :)
