I have one of the exact same units in our rig. As far as what I see from your picture, it is showing somewhat low voltage. This could be because the unit itself is defective, or your supply voltage is indeed low. I would test the reading against a more accurate digital voltage meter, and/or test it alongside another exact same unit back at the store for comparison.
Let us know.
