Answer / sam

It is easy. Find a manual and read it, that's what we all do.
The manufacturer can give you all the details of a specific
instrument much better that what anyone else can although it
seems that you already know quite a bit about it. Where did
you find that information? From the manual maybe, or are you
a scientist that knows about Archimedes theory as part of
you general knowledge about physics?
Good Luck
