The center knob moves the face so that you can rotate the numbers 2-24 to be in any position on the face. This I kind of knew, but what I found today was that if you spin the whole face (grab it from the trim ring and rotate it), the green line moves clockwise and it starts to tick like a timer!! I set the needle and aligned it with the 24 and I am headed to work for the day. I'll see where the needle ends up when I get home later.

So now I am confused. What is this thing...

I will put 12v to it tonight and see what happens.
