Troubleshooting a Built-In Test Failure
The built-in tests check the major Sentinel V modules and signal paths. If a built-in test fails, use the fol-
lowing steps to provide the needed information to the Teledyne RDI Field Service group to help reduce
the investigation process (see
How to Contact Teledyne RD Instruments
).
1. Repeat the failing test several times rotating the ADCP by 90 degrees each time. By doing so, it
may be determined that the failure is directional.
2. If other magnetic, acoustic, or high current systems are in the vicinity of the ADCP, if possible,
please power down the equipment and or remove the equipment (at least three meters away) dur-
ing diagnostic testing; re-run the tests.
3. Use the
panel or if the ADCP is configured for Real-Time then use the
and save the diagnostic log. Send the files to TRDI field service. This may aid TRDI engi-
neers in troubleshooting the instrument.
Troubleshooting Data Problems
This section contains the different tasks that should be performed on the site where experiencing data
quality issue(s).
1. Provide a copy of the deployment file (*.txt).
2. Provide a description of the environment where the ADCP is deploying; in particular, details on
water description (for instance: highly concentrated in sediment waters). Additionally, provide a
description of the intended deployment. Please provide details on environment commands, range
expected, standard deviation expected, and goal of the mission.
3. Recover the raw data from the instrument and send the complete deployment data together with a
description of the issue, and if possible some screenshots or ensemble numbers to locate region(s)
showing the unexpected data behavior. As previously mentioned in Troubleshooting a Built-In
Test Failure, if other devices are in the vicinity of the ADCP and are suspected to be the origin of
the data quality issue, if possible power the device down or remove it from the area (at least three
meters) and re-deploy.
