I have just purchased and am awaiting delivery of my first transmission densitometer--a Tobias TBX. All I know about it is that it comes with a power cord and will light up. I didn't pay a lot for it, but probably too much.

I own a 31-step Stouffer wedge. Where do I go from there?

I don't have a manual; I haven't the foggiest notion of what else I need to calibrate the thing or how to go about it.

I photograph with black and white film.

Any guidance or information will be appreciated.

Please don't transmit guffaws!
tnx
Warren
