Melico pm2 Colour Analyser, how do i use it.?

Just got a Melico pm2 Colour Analyser,but sadly no instructions.

Iv'e figured out most of the controls, but still need some advice

How do I match the settings on the PM2 with those of my Enlarger

The PM2's dial settings run up to 30 whilst those on my JOBO

Dichroic Enlarger run up to a value of 170. ( C:M:Y )

Any advice on this much appreciated.Or better still:

A copy of a manual if possible,many thanks Mike
