button to save these settings onto the computer as an xml file (*.xml). A
filename is suggested which includes the device type and the date. You can
change the name of the file to something different if you wish. Later on, you
can use the Read File button to retrieve the device settings that were saved to
an xml file, and re-apply them to the device with the Apply button.
When applying settings to a device using the Apply button, the Save screen
appears, allowing you to review and save the settings. Use the
Save
button to
save the *.xml file at that time, if desired.
8.1.6 Testing the Measurement Operation of the CRVW3
You can use the Device Configuration Utility in the lab to confirm the
measurement operations of the CRVW3. Once you have configured the
CRVW3 as desired, the CRVW3 will restart itself and automatically begin
measuring its sensors at the interval you have specified. The data is stored
immediately as each measurement is made.
When you first connect to the CRVW3, the following tabs are available:
Settings Editor , Logger Control , Data Monitor , Send OS , Troubleshoot ,
and Terminal . If any changes are made to settings within the Settings Editor
tab and its sub-tabs, all of these tabs except Settings Editor will disappear
until those changes are either applied or canceled.
Use the LoggerControl tab to check the real-time clock of the device. The
CRVW3’s clock can be synchronized with the PC clock using the Set Clock
button. If the
LoggerControl
tab is unable to obtain the time from the
CRVW3, there are connectivity problems that need to be resolved (see Section
13 , Troubleshooting CRVW3 Networks
(p. 101)
).
Use the Data Monitor tab to examine the data being stored in the final storage
tables and utility tables of the device. Click on a table’s name in the left pane,
and its latest stored record will be displayed in the right pane. The Status table
shows general information about the CRVW3 and its operation. The Public
table shows information about specific variables in use by the current program
configuration. The VW_Data table is the main storage table. This is where a
permanent history of sensor readings is stored. The DataTableInfo table gives
details about final storage tables in use by the device. If calibration settings are
