Aaah..,you were talking about ammeter showing
unsteadiness  and not vibration of instrument as whole
(I already started to wonder where and how you have
been putting that ammeter that 13 amps could shake it
-quite unlikely to happen).
Next time ,be more specific please.
John offered good explanation (if nothing else but
needle shakes).

cheers,
boris
