Ex WW2 German ohmmeter 5 ranges from 1 ohm to 10 Mohm which has been taken apart and the meter section had been converted into a 0-120 uA (0-120mV) meter. The resistance selection part is missing two knobs but otherwise seems to be complete. The original scale had been removed and replaced with a hand calibrated one (dated 9/12/49). I have married the two parts together and after some experimentation have discovered how it may have been intended to work. I have now made a new scale for the four lower ranges.
Do you know anything about this instrument or can you point me in the right direction for a circuit diagram and more importantly a picture of the original scale markings?
