reading multimeter?

My multimeter is somewhat different from yours. When I test a 1.2V battery and set the multimeter to 200m, it reads 3.1 or 3.2 (reverse black and red and I get -3.1). If I turn the dial to 2, I get .001. Can you explain what is going on. The instruction manual is totally unclear.

Do you have a picture of what you are looking at?

I have to say I tried it with some other batteries (6V and 9V) and they were pretty accurate. I think I should have selected the 2 Volt setting, which I did just now. The meter read 1.6, so I guess that 1.2 is an average and that over time the battery falls to below 1.2. I think I must have selected some setting other than 2V--because that seems to be the limit. My multimeter gives very scant directions on how to use it--just a bunch of charts--and it's confusing.

By the look of your picture, you have your meter set for continuity. Yes??

AA batteries (or similar) should be 1.5V on average. Rechargeable NiCAD batteries should be about 1.2V.

2V is the proper setting for reading batteries in the single digit voltage range.

It's just a matter of paying careful attention to selecting the type of unit that you are using. Figuring out the range takes more time and practice (and sometimes trial and error).
