Wael,
What are you referring to exactly? Calibration does say "Calibrate as per the analyser instructions." Here is where it is confusing. The "Calibration with analyser (oc VR3) directions should be what I need for SCR, since it's not a closed circuit rebreather. I shouldn't have to flush with O2, and those directions do not tell me to "FLUSH" & "EQUALISE." The "calibration with analyser (cc VR3)" directions do have the "FLUSH" & "EQUALISE" directions, but of course I'm not diving the computer in CCR Mode. Pain in the butt if you ask me.
