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 functioning 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.
120 66=Diluent
FO2 Bad
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
2
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. After completion of this test,
the congured diluent FHe is locked and cannot be changed.
120 0=time out 1)Ensure to conrm fraction via wet switch wet procedure. 2) If test failure
persists, contact an authorized Poseidon Service Center for repair.
52 Oxygen Fraction Conrmation test. Description; 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
Oxygen in the diluent. After completion of this test, the cong-
ured diluent FO2 is locked and cannot be changed.
120 0=time out 1)Ensure to conrm fraction via wet switch wet procedure. 2) If test failure
persists, contact an authorized Poseidon Service Center for repair.
50 Mouthpiece Closed-Circuit Position. This test requires that the
mouthpiece is set in Closed-Circuit (CC) position in order to
pass.
120 0=Timeout
1) Ensure that the mouthpiece is fully in the CC position (sometimes requires
rm pressing on the mouthpiece lever); 2) Ensure that the HUD is properly
positioned on the top of the mouthpiece, and that the exhaust cover is
holding it tightly in place; 3) If test failure persists, contact an authorized
Poseidon Service Center for repair.

1) Ensure dump valve on right counterlung is turned all the way clockwise;
2) Ensure oxygen cylinder valve is connected and turned on, with sufcient
pressure; 3) Inspect for tears, cuts or punctures in the counterlungs and
breathing hoses; 4) If test failure persists in spite of a sealed loop, contact
an authorized Poseidon Service Center for repair.
1) Ensure breathing loop is stable during test; 2) If test failure persists in spite
of a sealed and stable loop, contact an authorized Poseidon Service Center
for repair.
71=Oxygen
FO2 Bad
1) Ensure Diluent has correct oxygen percentage; 2) If test failure persists,
contact an authorized Poseidon Service Center for repair.
