Multimeter Problem.

Please help. I have a second hand P.O. meter no 12 C/1. It is a moving coil meter. It reads o.k. on Volts but under reads on Ohms. The zeroing pot does not seem to work. A label inside states that it has thick film components. Why won't it read Ohms accurately? Can it be repaired.

Thanks,

Z.

    Hello John, I have an AVO 8, but it has been converted to a table lamp and is now a decorative feature.
