    I was able to find a Fluke 79 II (series II) service manual but so far the only manual I've been able to find for the Fluke 79 Series III is a calibration manual. There is some commonality between series but am looking for the actual service manual for a "Fluke 79 III" (series III).

    That's a Fluke 77 Series III, I think similar but with different specs.

    e.g. the display resolutions are different

    77 Series III

    Digital: 3,200 counts, updates 2.5/sec
    Analog: 31 segments, updates 25/sec
    Response Time of Digital Display V ac < 2 s
    V dc < 1 s
    W < 1s to 320 kW, < 2s to 3.2 MW, < 10 s to 32 MW

    79 Series III

    Digital: 4000 counts, updates 4/sec
    Analog: 63 segments, updates 40/sec
    Frequency: 9,999 counts
    Capacitance: 9,999 counts
    V dc < 1 s
    W <1 s to 40 kW, <2 s to 4 MW, <10 s to 40 MW

    79 III calibration manual - http://assets.fluke.com/manuals/7926____cieng0200.pdf

    I did find a Fluke 79/26 Series III Multimeter Instruction Sheet but not the service manual. Downloaded and saved but have seem to lost the url.

    IIRC a 77 series IV

    Digital: 6000 counts, updates 4/sec
    Bar Graph: 33 segments; updates 32/sec
    Frequency: 10,000 counts
    Capacitance: 1,000 counts

    Oh, I'm sorry. I've been so fixed on the "III" :(
