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