X-Rite 810, some questions

Hi all,

Recently I bought the X-Rite 810 densitometer from a bankrupt’s estate. The machine is in good working order but it came without the manual and reflection plaque (PN 302-12) and a transmission film (PN 810-68) that are needed to calibrate it.

I think I need (at least I want to) to calibrate the machine and I don’t have the calibration plaque and film. Is there any way to do it without the original plauqeu and film? Or do I have to buy them, which I think would cost me more than I payed for the densitometer?

I will not meassure color, just B/W transmission in order to find my EI according to the Zone-system. There are som buttons and modes and I just can’t figure out how to do. Can anyone shed some light?

For instance, the second button on the left dials between Read-Green-Blue, Autocolor and Visual. What should i choose for b/w film?

Next button switshes between density and HD-LD. What is HD-LD and which one should i use?

I haven’t found a way to reset the readings, is there any?

I got the machine without the manual, is there anyone available that is downloadable?

Best regards

PS. I post this question in rec.photo.equipment.large-format, photo.net and LUSENET B&W Photo - Film & Processing if they adress different readers.
