I am sorry I have not got back to you sooner I have been in bed sick.
Many thanks Mike Wilde, Nige, Agx and largeformat pat for your responses. Your responses were a big help, I think I am starting to get a grasp on this analyser. Having the instruction manual would be a big help so Pat I have just sent you a PM, many thanks.
Once I have the analyser sorted hopefully I can do some serious RA-4 colour printing at last. The next step for me then is to start shooting 5x4 large format, I canít wait.
Many thanks, Geoff C.
