you should have it screwed to the back box not just floating,
i am pretty sure you have the multi meter set to the wrong position.
does the symbol where you have the multimeter set to look like this

i might be mistaken but from what i can make out you have it set to AC.
forgive me if i am wrong but it looks like the range you have it set to only has 2 selections which is usually the AC range
 

yes you are right ill recheck tonight when I finish work. Thanks
