Switch Setpoint
This menu is only available in CC mode when PPO2 mode is set to Int�
(internal)�
The internal PPO2 mode is used to calculate decompression for a
unconnected rebreather� In this case, the setpoints are switched in the
computer to approximate the rebreather setpoint�
During a dive the “Switch Setpoint” menu item will be the first item
displayed, since the “Turn Off” and “Calibrate” displays are disabled
when diving�
Pressing SELECT when this menu is displayed changes the PPO2
setpoint from the low setpoint to the high setpoint or vice-versa� To
redefine the PPO2 value of a setpoint, use the Dive Setup menu.
This menu item performs a manual switching of PPO2 setpoint� In
Auto SP Switch menu, the Petrel can be setup
to automatically perform setpoint switches at programmable depths�
When auto setpoint switches are enabled, this menu item is still
available to provide manual control�
