SWITCH SETPOINT
This menu is only available in CC mode.
The internal PPO2 mode is used to calculate decompression for an
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” 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 the System Setup Auto SP Switch menu, the Perdix 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.
