The pressure transducer, the ultrasonic transducers, cable connections,
and the electronic components of the AV Sensor are
encapsulated in plastic resin and are not user-serviceable. If any
part of the AV Sensor fails, it must be replaced.
Corresponding with a Teledyne Isco Technical Service Representative
can often resolve the problem without the need to return
the item. If the difficulty cannot be resolved you will be issued a
Return Authorization Number (RAN) and information on
returning it to the factory.
5.7.1 Diagnostics As a troubleshooting aid, many module functions can generate a
diagnostic file. With the assistance of a Teledyne Isco Technical
Service Representative, the diagnostic files can often be used to
isolate a problem.
To view a diagnostic file, connect to the site with Flowlink. View
the measurement tab of the suspect function and click on the
Diagnostics... button. The module then generates the file and
sends it to Flowlink where it is displayed as a text report.
Flowlink can also collect all of the diagnostic files while
retrieving data. The last available diagnostic files are always
kept in Flowlink’s database where they can be viewed “off-line”
at a later time. To enable Flowlink to automatically collect all
diagnostic files while retrieving the data, open the Utilities>Options
from the menu and check the Retrieve data gets text
reports box on the 2100 tab.
