Why is there a setpoint in the menu when the computer doesn control the setpoint?
The computer has two modes of operation, even when it isn’t controlling the setpoint. 1) External PPO2 In this mode the computer monitors the all three sensors votes on their values, averages the sensors that are voted in, and uses this average to calculate decompression and CNS loading. When the computer is switched to this mode, the prompts regarding setpoint don’t appear. 2) Setpoint PPO2 In this mode, the computer allows you to enter a low and high setpoint. You would typically enter these setpoints to be the same as you are using on your rebreather’s setpoint controller. You can then easily switch between these setpoints when you switch your rebreather’s setpoints. In addition, you can configure the computer to automatically switch setpoints up and down at depths that you select. That allows the computer to accurately track your rebreather’s setpoint without you ever having to touch the computer during a dive.
