Boy is that hard on the movement.:-)



And the internal shunt. :-)

I've seen a summer hire blow the shunt (epoxy housing, packed
with sand) in the amps plugin in an old HP Digital voltmeter. The rest
of it survived, and they were able to find a replacement precision
shunt.

Enjoy,

On the later Simson 260s a factory fuse was added in the shunt circuit
to save the rest of the meter from damage. I soldered in some of the
older meters that our company used.
