The CCR FIX SP mode is used for closed circuit diving with a fixed pO2 setpoint. This is the preferred mode, when the SYMBIOS HANDSET is not paired with a CCR.
In this mode it is possible to pair the dive computer with tank transmitters for O2 was well as diluent.
The sepoint can be selected in menu/CCR SETPOINT.
In menu/CCR Bailout it is possible to switch between CCR and Bailout.
This is an example of the screen during closed circuit diving with fixed setpoint. The left bar graph indicates the tank pressure of diluent (171 bar), and the right bar graph indicates the tank pressure of the O2 tank (98 bar).
If the no decompression limit is exceeded, the %_DEVICE%> indicates ceiling (in this example 3m),the estimated time to surface (5 min) in closed circuit (CC) mode the estimated time to surface (7 min) in bailout mode (BO).
Closed circuit time to surface estimation is based on the current pO2 setting.
Bailout time to surface estimation is based on the enabled gases in the gas table.
