Audio Alarm Speaker. This test measures the amount of elec-
trical current consumed by the speaker in the battery (Audio
Alarm), when activated.
Diluent Cylinder Pressure Sensor Validation. This test includes
a series of tests that conrm that power can be supplied to the
diluent cylinder pressure sensor, and that the signal from the
sensor is within limits (regardless of whether the cylinder valve
is turned on).
Oxygen Cylinder Pressure Sensor Validation. This test includes
a series of tests that conrm that power can be supplied to the
oxygen cylinder pressure sensor, and that the signal from the
sensor is within limits (regardless of whether the cylinder valve
is turned on).
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).

1) Standard Response; 2) If test failure persists, or the Audio Alarm speaker
does not sound during this test, contact an authorized Poseidon Service
Center for repair.

1) Inspect the primary 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.
27 Diluent Calibration Solenoid. This test measures the amount of
electrical current consumed by the diluent calibration solenoid
valve, when activated. It does not check that the solenoid
actually opens and closes (veried during the Positive Pressure
Loop Test, t49).

contact an authorized Poseidon Service Center for repair.
