    just got this function generator and dosn't seem to function.
    It only puts out .5v at max on any setting. It should be 10v on dc output.

    its one of those ebay deals seller said works perfect

    I tested with fluke 25 multimeter and tek 475a for volts and function .
    volt range id .01 to .5 v

    any ideas for the low volts output?

    From the block diagram there are 2 outputs - TTL and 600Ω. Are both of them having low outputs?

    See block attached.

    First: have you recapped the generator ) electrolytics get bad with age ad sitting a long time dormant will also age them significantly).

    Recapping the power caps? Im sure they need to be.

    That would be one or two power caps probably.
    there is no telling what else has drifted in value. I paid $80 for it and may just return the ebay item. If I had paid only $20 or so I would fix it. however, Its was described as fully functional working condition and that makes me want to return it even more!

    But they both only output .5vdc max

    They manual says 10vdc on the TTL when used as a DC power supply.
    All buttons out mode

    With the DC offset in the 12:00 position, the TTL out reads 2V dc and about 1.9 AC.
    In the 600 ohm out, it reads about 9.7 VAC.

    I can't find my manual, but those are the observed readings.

    OK, since you've made up your mind to send it back. There is no point for further questions. But just in case you changed your mind here's the link for the schematics.

    I have the B&K 3010 and schematics so if you decide to trouble shoot it I can be of assistance.
