53 Oxygen Sensor Calibration. Like the Positive Pressure Loop
Test (t49), this test check several things besides performing an
oxygen sensor calibration, including the composition of the
diluent and oxygen supplies, the proper funcioning of both the
oxygen and diluent calibration solenoid valves, and other
parameters associated with the oxygen sensor behavior. The
mouthpiece must remain in the CC position for the duration of
this test.

1) Ensure Diluent and Oxygen cylinders have the correct oxygen percent-
age; 2) Make sure that you have connected the oxygen- and diluent tanks to
the correct connection on the pneumatic block; 3) Replace Primary oxygen
sensor with a known good sensor; 4) Ensure CO

absorbent cartridge is
installed correctly; 5) Ensure breathing loop temperature is within range
limits; 6) If test failure persist, contact an authorized Poseidon Service Center
for repair.

51 Helium Fraction Conrmation test.
This test will be run if a rig is enabled for decompression or if
the diluent conguration is not air. It will display the assumed
fraction of Helium in the diluent.

persists, contact an authorized Poseidon Service Center for repair.
