I bought a modified Bird meter with the 2x 5x 9 volt multiplier. I started testing some 9v units I had in a box and they were reading 11.4 - 14.6 volts. Is this typical? Is there that much voltage loss in these wall units?
Am I right to be concerned about replacing the 9v battery with a wall wort testing at 14.6? 11.4 seems more acceptable.
