48 Sufcient Battery Capacity. This test ensures that the battery
has a sufcient charge to start a dive. The minimum necessary
charge depends on how long it has been (both in terms of time
and number of charge cycles) since the last Learn Cycle (see
Chapter 1). If 160 days have elapsed since the last Learn Cycle,
this test will always fail.

1) Standard Response; Insert battery into the charger.
2) Subject battery to a Learn Cycle on the charger (see Chapter 1);
3) If test continues to fail, try a different battery (subject to decompression
data issues);
4) If test failure persists, contact an authorized Poseidon Service Center for
repair.
45 Sufcient Diluent Supply Pressure. This test requires that the
diluent cylinder contains sufcient pressure for a dive to be
started (at least 25% of maximum capacity).
120 0=Timeout 1) Ensure the diluent cylinder is connected to the diluent regulator, and that
the valve is turned on; 2) Ensure that the diluent cylinder contains sufcient
pressure; 3) If test failure persists, contact an authorized Poseidon Service
Center for repair.
49 Positive Pressure Loop Test. Besides checking for leaks in the
breathing loop, this test checks several additional things,
including leaks in any of the four solenoid valves, that gas
actually passes through each of the two metabolic solenoid
valves, that the dump valve on the right counterlung is secured,
and that the depth sensor is sensitive to small pressue changes.
Because there are several things being checked during this
test, there are also several different kinds of failures, with different
solutions.

pressure
1) Ensure mouthpiece is in OC mode; 2) Ensure oxygen cylinder valve is
connected and turned on, with sufcient pressure; 3) Ensure all connections,
seals, and o-rings for the breathing hose connections, Water Diversion
Manifolds, Electronics Module, and bottom cover of the gas processing unit
are attached and seated correctly; 4) Inspect for tears, cuts or punctures in
the counterlungs and breathing hoses; 5) If test failure persists in spite of a
sealed loop, contact an authorized Poseidon Service Center for repair.
44 Sufcient Oxygen Supply Pressure. This test requires that the
oxygen cylinder contains sufcient pressure for a dive to be
started (at least 25% of maximum capacity).
120 0=Timeout 1) Ensure the oxygen cylinder is connected to the oxygen regulator, and that
the valve is turned on; 2) Ensure that the oxygen cylinder contains sufcient
pressure; 3) If test failure persists, contact an authorized Poseidon Service
Center for repair.
43 Mouthpiece Open-Circuit Position. This test requires that the
mouthpiece is set in Open-Circuit (OC) position in order to
pass.
120 0=Timeout
1) Ensure that the moutpiece is fully in the OC 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.
