I'm getting back into film photography after a 12-or-so year hiatus, and picked up an older Photronix Delta III transmission densitometer to help me in various tasks. Unfortunately, it did not come with instructions or a calibrated wedge. I need to call up Stouffer to get a new wedge, and I'd like to be prepared in case I need to recalibrate the densitometer. Does anyone happen to still have a scan of the instructions & calibration procedures for this densitometer? I took the bottom off & found three potentiometers, and while I could probably figure out how to use them, I would prefer to know the procedure before I get started. I saw some instructions being passed around in a post from 2010, but I hated to reactivate such an old thread!

If anyone still uses one of these and can help, I appreciate it!
