I have aquired a Durst Diprotim (with instruction leaflet) which is great for processing with Caffenol Cl using the semi stand method as it can be set to count down consecutively with all the agitation stages having a 5 second warning before hitting their mark so have set it up for 30secs, 2 mins, 4 mins, 8 mins, 16 mins, 34 mins 30 secs to give a total processing time of 65 minutes.
Now as I have the instruction sheet, my question is (which is not answered in the instructions) is: What is the flap and jotter type area at the top of the timer for?
