Dear Steve,
I apologize for what you perceive as rudeness, and also for my mis-remembering: I was thinking of the original Luna-Pro, not the F, which I also have. Of course the F does not use silver cells, but as you say, a 9v battery.
I'd still ask, though, why you need a manual. In incident mode it is used like any other incident meter; in reflected mode, like any other reflected meter. ANY book or web-site on metering technique should tell you all you need to know: I'm not quite sure what you mean by 'collective purposes'. There is a 'correction' ring, which is best left on '0'; a battery check (the little green button on the right); a flash/ambient button (on the left, in for ambient, out for flash). Press the big red button (upper left) to take a reading; use the dial to get a null reading. The ISO dial is not hard to figure; use the main index, or one of the Zone indices if you are reading a limited area (a spot meter is a better bet).
With the exception of the gate time when mixing ambient and flash, for which I freeld admit you need the instruction book, I really don't see what there is on this meter to require further explanation.
What do you need to know? I'll help if I can.
Cheers,
R.
