CRVW3 3-Channel Vibrating-Wire Datalogger same computer that runs LoggerNet or on a different computer accessible from the LoggerNet computer via TCP/IP. For more information, refer to the LNDB product website: www.campbellsci.com/lndb The RTMC and RTMC Pro products can be used to create screens for viewing real-time data as it is collected by LoggerNet. However, the RTMC Pro product 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.

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 See Section 11.3, Station Health Monitoring, 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 A, Updating CRVW3 Firmware, 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, then the sensors may need to be periodically calibrated using the Calibration Wizard. See Appendix E, Engineering Output and Calibration, 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, 79

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

See Section 11.3,

Station Health Monitoring

, 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 A,

Updating CRVW3 Firmware

, 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, then the

sensors may need to be periodically calibrated using the Calibration Wizard.

See Appendix E,

Engineering Output and Calibration

, 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,
