Do you have a potato?... > PS this story doesn't make sense because you can tell when a voltmeter is out of range. It's also a bit sloppy with the bounds. To me, "reads only as far as 100" includes 100V, whereas the measured voltages only go as high as 99V.

While we're complaining, you can't measure the "voltage" of an electron tube out of circuit.

Sure you can, just buy a SMU (source measurement unit, few multimeters cobbled together with 4 quadrant power supply)
