Terry - what firmware version do you have? (Check by reading the display during power-up). If it is earlier than v8.5 then the split grade mode works slightly differently and adjusting either channel will affect overall exposure. However, the comments regarding filters are still valid, on a dichro head set max Y when using ch.1 and max M for ch.2.
