I used to. I don't recall ever having calibrated anything (I didn't have a probe to go with it). Just dial in contrast on the panel, set time and there you go. I very rarely used the consecutive exposure functionality since I didn't (still don't) do a lot of split grade printing, but it worked OK.
Doesn't sound familiar to me. Mine allowed to set the contrast grade, which affected blue and green together. No filters adjusted; the exposure of the blue and green channels was varied by dimming both bulbs as I recall.
If you want to make split grade prints, just follow any of the many tutorials out there. For instance, start with making a grade 0 test strip, then a second strip exposed to the time you established for grade 0 and the the grade 5 increments on top of that. Choose the one that appeals to you, do a full sheet, burn & dodge the next sheet as desired.
Whether you use grade 0 and grade 5 or some other combination (e.g. grade 1 & 4) doesn't really matter. The process is the same.
The exposure times you determine based on paper choice, enlargement, lens aperture, negative density etc. I never worried about any of this and just printed the test strips, changing times if I didn't see what I liked.
What exactly is your question? It's not entirely clear to me where you're getting stuck. Have you already tried it?
