I have a  30L-1 with a real "bouncy" meter.  When switching from DC volts 
(~1900V)  to either Tune or DC Amps, the meter swings down to about minus 
400-600v  before coming back to rest at Zero.  Also, when first powering on, it  
overshoots and pins the DC Volt scale.  Checking the same action on my  other 
30L-1 shows that there is no overswing to negative numbers when  switching deom DC 
Volts to Tune or DC Amps and it goes quickly and  smoothly
from 1900 to zero.  Is the wide swing indicative of a bad  meter?

Sounds like it could be a bad meter shunt resistor for the position that it  
bounces in.  There are shunts for each value the meter reads.   Lou
