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
