Digital Hydrometer issue

I decided to do a salt test on mine. It's been in the bag for about 6 hours now. It's reading 76F. The problem is, when I turn the dial, it does not change the reading. Logically, if I turn the dial all the way up, and it still reads 76F, I SHOULD be able to remember its +1...but am I really sure its +1? Maybe its just reading very wrong...how am I to be sure?!
