→ Salinity ( Figure 33 )
Salinity is determined by calculations derived from the conductivity and
temperature sensors.
Because salinity is an important factor in determining dissolved oxygen,
YSI does not recommend calibrating or taking dissolved oxygen
measurements without the conductivity/temperature sensor installed in
the bulkhead.

GPS turns the ProDSS Global Positioning System On or Off. The
symbol is shown when a GPS signal is received ( Figure 34 ).
When enabled, the GPS coordinates will be saved with the GLP file and
logged data.
