    Multimeter "s/o" select option

    Hello,
    Today I have bought used Voltcraft multimeter. It has option to measure "S/O". I don't know what this means. Googling I have found "signal out" but that is still unclear to me. It is between buzzer (continuity) and TEMP. The multimeter is M4660A.

    Do you what this is and when it is used?

    It seems it is signal generator with possibility to change frequency, but what waveform?

    From the manual
    With the
    function "S/O" = Signal Out, 10 different preset frequencies from 10 Hz
    to 10.24 KHz can be recalled. For this a special adapter (option) is needed
    which is connected to the CAP-measuring socket.
    Could used for signal injection for testing an audio amp for example, I'm sure there are many other uses as well See Page #15

      Thank you. I missed that one potential application. I was wondering where that could be useful.
