There should be a little switch on the top of the camera, on the same side as the meter knob. Flipping this switch should conceal or reveal a little red dot. This is to switch between high brightness and low brightness range for the meter. If you are metering in dim light, flip the switch so the red dot is exposed. You should see the meter needle swing down further toward the back of the camera. When the red dot is exposed, take your readings from the red window on the dial (the opening toward the back/bottom of the camera). You'll get a number in that window, like 7 or 8. In the high range setting, you'll get numbers more like 12, 13 or 14 in the top/front/white window. Use that to set the EV on the front of the camera. Does that make it clearer?
