I have found the L-208 to be inconsistent. When turning the dial to match the meter needle, I always turn it anticlockwise because there is some slack (1/2 stop) in the mechanism. Also, I would recommend that you calibrate it against a known good meter because it isn't particularly accurate. I set the film speed on an adjusted setting so it matches other meters, and a different film speed for incident and reflected readings. Apart from that, I do like meter needles rather than digital outputs.
