OXYGEN ANALYZER
OVERVIEW
The DSX can be used with the O2 Analyzer accessory and an "R22D" style oxygen sensor (sold separately) to
analyze the oxygen content of your diving cylinders.
!
DANGER: DO NOT use expired sensors. Follow all O2 sensor manufacturer recommendations for han-
dling and use of their sensor.
!
DANGER: Allow new O2 sensors to acclimate and stabilize in air after opening, following all sensor
manufacturer guidelines.
!
DANGER: Your new DSX and O2 Analyzer cable are paired and precisely tuned at the factory, to com-
pensate for resistance in the cable. ONLY use the cable that ships with your DSX. The cable serial number
(labeled on the cable) must match the serial number that displays on your DSX (O2 Analyzer Sub Menu)
screen. Contact your Apeks Dealer for assistance if the Oxygen Analyzer cable ever needs to be replaced.
3. Remove the sensor strap, and retaining screws with a philips head screwdriver.
