Hi
Has anyone ever tried an automatic setpoint adjuster, not depth triggered but the setpoint changes according to the loop PO2.
I am thinking about setting the lower setpoint at say 0.7. If a manual injection was done to push the setpoint to 1.1 then the controller would automatically set the sp to 1.3 and hold it. To lower the SP just flush and dump till the Loop is under 0.9 and the SP is switched to 0.7 again. This may be a bit fiddly on the ascent but it also means you dont need a separate switch for setpoint adjustment.
I have thought it through and I cant see a problem but I am sure someone out there will tell me why it wont work. There must be a point in the dive where it could cause problems but I cant see it at the moment.
