You can't measure the mat resistance with an ohm meter.  Or to be more 
accurate, if you get a reading on the meter, then the resistance is way 
too low.  The resistance between a pair of meter probes would typically 
be in the range of 100's of megohms or more, which is too high to 
measure with a multimeter.

At the bottom of this message is a description of the test procedure I used:
