Mode Setup
Mode
Mode sets which breathing circuit configurations are available:
CC/BO
OC Tec
OC Rec (default)
Gauge (e.g. bottom timer mode)
When changing to or from Gauge mode, the decompression
tissues are cleared. This is because when in Gauge mode the Perdix
does not know what gas you are breathing, , and therefore cannot
track inert gas loading.
Salinity
Water type (salinity) affects how the measured pressure is
converted to depth. Settings:
Fresh
EN13319
Salt
Density of freshwater and saltwater differ by about 3%. Saltwater,
being denser, will display a shallower depth for the same measured
pressure versus the Fresh setting.
The EN13319 value is between Fresh and Salt. It is from the
European CE standard for dive computers, and is the Perdix’s
default value.
