•
Your H-ADCP fails any of the following PA tests provided the items indicated by {} have been
checked:
Recorder Tests:
Any recorder tests fails {provided that the PCMCIA card(s) have been checked for proper
installation, operation and they are DOS formatted; we STRONGLY recommend checking
PCMCIA cards in a computer before replacing the boards}
System Tests:
Transmit {if the H-ADCP fails when it is in water and air bubbles have been rubbed from
the faces}
Sensor Tests:
H/W Operation {if the H-ADCP fails when it is NOT sitting/resting on its side, or located
near a large magnetic field like a motor in a boat}
The spare boards kit will not correct any of the following failures:
•
A damaged beam or its urethane surface
•
Damage to the transducer beam connections below the copper shield
•
If it passes all PA tests and yet the data is all marked as bad
•
Fails the following PA test:
System Tests:
Wide Bandwidth {bandwidth tests may fail due to external interference}
Narrow Bandwidth {bandwidth tests may fail due to external interference}
