LNDB
product website:
RTMC
and
RTMC Pro
can be used to create screens for viewing real-time data
as it is collected by
LoggerNet
.
RTMC Pro
can also be used to create
customized screens for viewing historical data that resides in .DAT files or in
an
LNDB
database. Once screens have been created with this product, they can
be viewed using the
RTMC Runtime
viewer, or they can be published out as
web-enabled sites using the
CSI Web Server
product. Refer to these product

12. Maintenance of CRVW3 Networks
After your CRVW3 stations have been operating for some time, there may be
periodic maintenance tasks that need to be performed. Routine maintenance is
a key activity that helps ensure the healthy and ongoing operation of your
system.
Some of these maintenance tasks can be performed remotely using
LoggerNet
and related software tools. For other tasks, a visit to the CRVW3 deployment
site is necessary.
12.1 CRVW3 Maintenance with
LoggerNet
(p. 93)
, for details about how to use
LoggerNet
to periodically check the health of a CRVW3 station.
From time to time, Campbell Scientific will release updates to the CRVW3
firmware, and make these available for download from the Campbell Scientific
website. See Appendix
(p. A-1)
, for details about
how to update the CRVW3 firmware, including remote updates made from
within
LoggerNet
.
If the measurement output of the CRVW3 has been configured for engineering
output and baseline readings are used as part of that calculation, the sensors
may need to be periodically calibrated using the Calibration Wizard. See
Engineering Output and Calibration
(p. E-1)
, for details about
calibration and using the Calibration Wizard.
12.1.1 Battery Monitoring
The status of the battery on the CRVW3 should be monitored using the
Battery
field in the
Status
table. Voltage levels greater than 12 V indicate that
the charge circuit is active and charging the battery. Levels of 12 V or less
indicate no charging is active. Once battery voltage reaches 10.5 V,
functionality on the device begins to be restricted, and the
Low10_5_Count
value will be incremented. Full shutdown of the device occurs at 9.5 V.
