RE: Cibachrome Exposure Monitor M-1

[Paul Ewins]

Does anybody have one of these or know how it works? I've bought one very
cheaply and I hope to use it for B&W printing. It has an on/off switch, two
red LEDs and a calibration dial marked from 0 to 100. I guess I could work
it out by trial and error, but would prefer some experienced advice or a
copy of the manual.
