OXYGEN ANALYZER
USING THE O2 ANALYZER WITH THE DSX
First plug the O2 Analyzer cable into the DSX. To access the O2 Analyzer menu, hold the Left and Right buttons
while on the Surface Main screen in CC, OC, or SM Mode. Alternately, O2 Analyzer is an option in the Set Gases
Menu of those modes, see p. 32. The first step to use the analyzer is to calibrate the sensor.

CALIBRATION
Changing enviornmental conditions and the diminishing output of an O
2
sensor can affect the gas analysis. For
this reason it is good practice to calibrate periodically, minimum of every day of use. Set the FO
2
(Fraction of Oxy-
gen) of the known gas.
1. Hold the O2 Analyzer dome cap firmly against the known (control) gas tank valve or expose in air. Slowly open
the tank valve only part way if using a cylinder gas to calibrate with. The flow rate should not be excessive (≤ 10
liters per minute).
2. Expose the sensor until the DSX confirms the calibration.
3. If any error codes are displayed, take corrective action before attempting to calibrate again.
4. After successful calibration you may use the Analyze feature.
!
DANGER: Moisture in the gas can create false readings.
!
DANGER: DO NOT proceed until a good calibration is achieved.
NOTES: DO NOT calibrate with excessive flow rates (greater than 10 liters per minute).
NOTES: Dropping or mishandling the O2 Analyzer can damage the O
2
Sensor or electronics. It is also
important to keep the O2 Analyzer dry.

DANGER: Your new DSX and O2 Analyzer cable are paired and
precisely tuned at the factory, to compensate 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.
