"> Just convert the 3 pin wall plug to a 2 pin
    >wall plug.  (lift the ground pin)"

We had a young tech who did this to measure
the grid drive to a small TWT (traveling wave
tube) one day (p/o the GM (Ground Mappping) RADAR
in a Panavia Tornado Nose RADAR) - the only problem
was the drive was WRT (with respect to) the cathode
of the TWT - and the cathode sat around -3000 VDC ...
the Tek 475 *did* stand off this voltage (the spec
states something like 500 V or so) ...

Normally a special isolation transformer and
insulated 'cage' for the scope was used - someone
had not informed this young man as part of his
training however.
