[AT] Reading ohms on a digital VOM

[charles bridges]

I have a digital VOM and don't understand how to read it.  On the ohm scale,
the switch is marked  as follows.  (Ohm emblem)-(200)-(2k)-(20k)-(200k)-
(2m)-(20m).  What does the M and K beside the numbers mean?

In trying to use it to check a coil.  The coil should have 0.81 to 0.99
primary resistance.  If I set the meter on the ohm emblem it reads  .003.
If on the 200 scale it reads 01.3.  On the 2k it reads .001. On the  20k it
reads 0.00.  Does this mean the resistance is off the scale at the 20k
setting?

There must be something I am missing here, and I figured some of you guys
would know.

Thanks in advance
