    Can anyone tell me how I can measure coil inductance with a DMM
    without a special add-on circuit?

    Find a DMM with an inductance range.

    Do you have any other test equipment that we can also hook up?

    I do have one with inductance, but feeding a signal into the inductor
    and resistance should give you a voltage that will indicate inductance.
    I can't remember if the meter i have also measures capacitance, but
    the procedure is the same.

    Put a sine gen on a RL cct and use the DMM to measure the AC level
    across the coil.
    Then do math..
    Beware of the limitations and restrictions..

    DMMs with capacitance ranges are common enough, but I've never seen one with
    inductance - it probably wouldn't be very accurate if you did find one.

    Peak Atlas instruments do a LCR meter for about the price of a good DMM.

    ARRL Radio Amateurs Handbook had(has?) a circuit for measuring inductance
    with a DMM. IIRC,there was a company that offered a kit of parts + PCB,too.


    Service to my country? Been there, Done that, and I've got my DD214 to
    prove it.
