    MK III ist die verbesserte Version von MK II (zusätzlich Sicherung zum Schutz des R-Messbereiches, mehr innere Widerstände im Aufbau).

    Replaced copper-oxide with germanium rectifiers to improve AC sensitivity and frequency response (typically 20K Hz at 2.5V).

    Fuse added to low ohms ranges. Early models of the Mk3 do not incorporate the additional protection features described below and shown on the circuit diagram.

    DC 2.5, 10, 25, 100, 250, 500, 1000, 2500 volts - sensitivity 50 uA
    DC 0.05, 0.25, 1, 10, 100 mA, 1, 10 A
    AC 2.5, 10, 25, 100, 250, 1000, 2500 volts - 
    sensitivity: 1 mA on 10+ volts, 10 mA on 2.5
    AC 100 mA, 1, 2.5, 10 A
    R 2k, 200k, 20 M ohm (20, 2k, 200k ohm center)
    Also LR (= 0.325 volts, for use with low range of Resistance Range Extension unit) and Ins. (2 M ohm center, with external power)
