I know; I was just speculating on how he might have blown it up.  I had one 
for years, and connected it across the meters of several transmitters, some 
tube, some solid state.  I also used it with a Heathkit VTVM which could 
read up to 1500 volts, and I never came close to blowing it up.  I think the 
instructions had some caution about taking care not to ground either side of 
the input, or having too high a voltage between the input terminals, but I 
may have read that somewhere else.
