Been sitting back and watching what may come of this thread.
I don't think it matters what the resistance of the meter
movement is, the 30Ω load that Gus has applied to the meter is
an excellent way of checking it in the full position. If you
wanted to check the meter thru the entire range you could
obtain an accurate rheostat so you could vary the
resistance from 0Ω to 30Ω.

change the resistance of the coils inside.
