Really?  Or is the lowest range just 0-200 ohms?  I'd be surprised if it
couldn't measure lower resistances.  Have you tried it?  When measuring
low resistances, it's a good idea to short the probes together and note
the reading, first.  I've seen cheap test lead sets that had over 2 ohms
of resistance all by themselves.

If it can't measure that low, I suggest buying a 270 ohm resistor,
measuring it first, then putting it in series with a speaker and using
subtraction. ;)

(Then go buy a different DMM, because one that can't measure low
resistances will be somewhat limited when it comes to automotive
troubleshooting.)
