[volt-nuts] HP419A Meter Pegged to Right

My second oscilloscope was a new Tek 515 which I got for the student price and picked up from the Tek sales office on 
San Antonio Rd in Palo Alto.  On the tour they showed me the washing booth where they used a water soap solution to 
spray wash the complete scope.  There were no parts in the design that would absorb water.

When washing semiconductor wafers after the DI water rinse they used an alcohol rinse then a compressed clean air blow 
off.  The alcohol sucks up the water and what small amount that's left after the air evaporates quickly.
