You might try connecting several diodes in series in two reverse parallel strings. A single diode will begin conducting at around 0.7 V so if the voltage across the meter coil the exceeds this level the diode will conduct and affect the meter reading.
If you connect three diodes in series, conduction will not start until about 2 V which should not affect the indicated reading and still afford some protection.
