With my DMM I have to remember to subtract about 0.2R every time. But it
isn't always the same - sometimes its a few R, very occasionally it
actually reads zero with the probes shorted.

Its probably the sockets in the front so new leads/probes probably
wouldn't fix it. I have newer meters, but I've had that on a long time and
its become comfortable.

Some of my meters have a button on them that will set the display to 'zero'
for most functions.

Some of the other inexpensive DMMs do not have any way to zero out the
resistance.
I even had an old one somewhere that had a zero adjustment pot similar to
my trusty Simpson 260 analog.
