2) The full scale deflection can be calibrated by feeding the FS current
and adjusting the counter weight.


Uhhh - those counter-weights aren't for that purpose - they are there to
balance the movement regardless of position (vertical - laying down, on
it's side, etc.). They are to be adjusted so that the meter needle
doesn't move (i.e. stays on zero) regardless of the meter's physical
orientation. If you try to "calibrate" the movement with those - the
meter will become very "gravity" sensitive - and loose much accuracy -
depending on "how it sits"...
