Yes.. now.. that I have part clear.. On the front of the camera there two sets of numbers. One is is for for F and T Fstop and Time. I understand. just left of that, there a set of number that you discribed. with that said. There is a black arrow that points to the numbers got that that.. there is no center point in this area. so there a 5 number swing. Do put the arrow on the first number that shows in this area? Or do i put the arrow in the center of the area? Also how do I know this is zero'd?
