Calibrate a transmission densitometer

[ic-racer]

PM me if you need the Tobias repair manual on PDF.

Not sure how we get 30 posts on this when the calibration procedure is a single paragraph in the manual.

The one not had no values with my purchase, I've no idea if nominal values were supposed to be shown. My uncredentialed opinion is that I only care that the value my densitometer returns is accurate to within the stated tolerance of the machine, and I do that by calibrating it as per the manufacturer's recommendation.

Sorry if you got the wrong one. The nominal values with tolerances are given on the Stouffer website.

If you're satisfied with the performance of your meter, why did you order the step wedge in the first place???

to carryout personal film speed tests and development time tests as described here; to test for relative ISO Range Numbers of my VC paper as described here. Although my meter does not require a step tablet, both of these testing methods that I use do, and I'm quite pleased with them.
