Sure you want rid of it? These are perfect for guessing print times in black and white.
Example I use Yellow for Shadow (thin) and Magenta for Highlight (dense).
Then when I have a good base print time, measure a shadow in yellow channel and dial in, for example 32 seconds. Then switch to magenta and dial in 32 seconds for a highlight.
For a change of height or negative just directly read off the possible seconds and if highlight and shadow both tell you 40 seconds you can try that base time for a test strip.
P.S. I am not in the market for more. But that unit is probably working just fine. Everyone kind of needs one.
