41 This test requires the user to conrm that:
1. They have a canister installed
2. It contains sufcient unused absorbent to complete the
dive.
120 0=Timeout 1)Ensure to conrm canister good via wet switch wet procedure. 2) If test
failure persists, contact an authorized Poseidon Service Center for repair.
38 Depth/Temperature Sensor Validation. This test ensures that
the temperature sensor embedded in the depth sensor is
working correctly.

1) Standard Response; 2) If test continues to fail, ensure loop temperature
is within limits; 3) If test failure persists, contact an authorized Poseidon
Service Center for repair.
35 Secondary Oxygen Sensor Validation. This test measures the
voltage output from the secondary oxygen sensor, to ensure it
exceeds a minimum threshold value. Although it is possible
that the gas mixture in the breathing loop is hypoxic, a failure
of this test more likely indicates a failed oxygen sensor and / or
a broken wire. This test does not ensure proper function of the
sensor (veried during the calibration routine, t53).

1) Inspect the secondary oxygen sensor, the wires leading from it, and the
electrical contacts at the back of the sensor cavity, and replace the sensor
and/or wires if either are suspect; 2) Standard Response; 3) If test failure
persists, contact an authorized Poseidon Service Center for repair.
34 Primary Oxygen Sensor Validation. This test measures the
voltage output from the primary oxygen sensor, to ensure it
exceeds a minimum threshold value. Although it is possible
that the gas mixture in the breathing loop is hypoxic, a failure
of this test more likely indicates a failed oxygen sensor and / or
a broken wire. This test does not ensure proper function of the
sensor (veried during the calibration routine, t53).
