Any one familiar with Wallner CA 526 color analyser?

Some time ago I bought a combination of a timer, densitometer and color analyser at ebay. The color analyser is Wallner CA526 and I don't have the instruction manual for it. Is there anyone here who has or knows this device and could provide me either with a copy of the manual or at least with some basic principles how to calibrate and use this analyser?

I've got the same rig and have started a group for sharing information. I've got pdf files of the manuals posted at:

These must be infrequent to stumble into as I've not had single user interact through the group as yet.

Thanks, Craig, that's perfect.
