Strange VOM Issue

All I was wanting was a backup in case the battery died in my Fluke.....which it did right after I checked the well voltage.....which led me to believe I might have damaged it, but I didn't, the battery just crapped out at the same time, it's working fine again with a new battery now. I just got this one tonight, on evilbay. I know it's not a high end one, but it will be fine for a backup, plus it gives me an analog one to do "different things" with. Notice it does have a 15V DC scale.

Hey I have one of these. I still use it once in a while. But my go to meter is a Fluke 87. Great meter.
