battery drain

To troubleshoot a battery drain, I charged up the battery in my
'91 200 20V.  I reinstalled the battery. I attached the negative
(ground) cable to the battery negative and left the positive cable
free. I then attached my digital volt meter (DVM) probes between
the battery positive and the positive cable, to see what the
battery drain might be.  I tried all 3 m.amp settings (2000u,
200m, and 20m) and couldn't get a reading -- the DVM showed 0 on
all 3 settings.

Not being an EE, am I doing this right?
Should I see a reading?
Could I have burnt out the m.amp reading?

I swapped the DVM probes for m.amps rather than the Ohms position
they had been in.  The voltage part of the DVM still works.
