In order of probability:

1. Dirty battery contacts. Clean the contacts and possibly replace
the battery.

2. Dirty test probe contacts, broken test probe wires, corroded test
probe tip. Clean or replace.

3. Dirty rotary switch. Spray with a small amount of contact
cleaner.

4. Dirty fuse contacts or bad fuse. Clean and/or replace fuse.


What about

5. Dodgy zeroing pot (internal, external, both) ?

It's a minor nuisance on one battery/pocket analogue meter
of mine, but then I don't try and guess resistances off it!
