Yes, it is possible. You'd need to wire a resistor of identical value to the coil resistance of the 100uA meter in parallel with the 100uA meter. The resistor and the meter would then share the current equally i.e. with 200uA flowing in the combination the resistor would take 100uA and the meter would take 100uA and indicate full scale.

Ah, that sounds good. But next question: measuring the coil resistance on the meter, is that just a matter of measuring ohms between the two connector points on the meter?
