    Need densitometer manual

    I've inherited a TRX-S combo densitometer, but can't find an owner's manual. Unfortunately, the manufacturer was no help. If anyone has such an item, I'd be appreciative if you could share it. Thanks, StevenClick image for larger version.

    Is it TOBIAS? If so, it might look like the TBX on the back. The two trimmers for each color are for "zero" and "cal" which is the "high density" reading. I use about 2.0 log d for the "high density" calibration. I could copy the manual page, but it really is only a paragraph or two and indicates where the trimmers are and what they do.

    Yes, that is a Tobias. The trimmers are on the side, did you find them?
