I decided to take off on a little photographic road trip in northern Oregon with my 4x5 Toyo and Fuji medium format. All was well until this afternoon when my battery died in my Sekonic L-508. I changed the battery and I was back in business, expect that my meter went crazy. When I went to change the ISO it would only "toggle" between two settings (I.e. 400 & 650). After playing with it for some time I realized that I could change ISO #1 if I changed ISO #2 the opposite direction! I have tried removing and reinstalling the battery several times. Does anyone have any thoughts?
