I've tried filtering and turning up my filter count and various other settings on the DMM to try to accomplish this measurement. Could anyone offer a suggestion on how to measure low resistance values with this instrument?

Is the chassis floating or does it have a connection to earth ground?
As a sanity check, try using a length of thick wire, such as an unfolded paper clip, to present a low ohms DUT. Place the cables at different lengths along the wire to see if the ohms increases with length.
DMM calibration for Zero Ohms (at input) this is made at 23C, In a cold room, zero Ohms CAL this gets negative Ohm values that Zero-Ohm math setting (offset compensation) cannot remove.
For best results DUT temperature should be at above 21C.
