Resurrecting an old thread here. So, I've checked the connectors in the back, their spacing and etc. I think I understand how the system works (I work IT and deal with weird crap like this all the time) and here's the skibby: under lowlight situations it reads the proper incident reading and displays it like I would expect--yes it's in AMBI mode--but the moment I step into harsher light it jumps to extreme readings like f/90 @ 500 or so. I feel like I've read the manual a thousand times and even the guy who used this before me is scratching his head. Any thoughts again?
