10.1.2 Sensor spectrum checks
Periodic verification that the CRVW3 is making proper readings from its sensors is
recommended. During installation or during on-site maintenance, this can be done using the
Troubleshoot tab in
Device Configuration Utility
. Making a similar spectrum check on a CRVW3
using
LoggerNet
and a remote connection if the device has a radio option is also possible. The
creation of a binary file can be triggered, and then that file can be retrieved to the
LoggerNet
computer station using File Control.
Device Configuration Utility
can then be used to view the
spectrum and diagnostic contents associated with that file. In this way, you can see the spectrum
information on a remote CRVW3 without making a field visit.
Follow this process to check the spectrum on a remote CRVW3 station:
1. Use Connect Screen to establish a connection with the CRVW3 station of interest.
2. Open the Status table in the Table Monitor dropdown.
3. Set the Channel_Diag value to match the channel to be tested (1, 2, or 3).
4. Set the desired low frequency and high frequency (in Hz) for the measurement using the
Begin_Freq_Diag and End_Freq_Diag fields.
5. Set the excitation level for the measurement using Excitation_Opt_Diag. Use 120 for 12 VDC,
50 for 5 VDC, and 20 for 2 VDC excitation.
6. Set the Run_Diag value to 1 to trigger the measurement. Watch and wait for the value to be
set back to 0 to indicate that the test measurement is complete. Ensure that the Diag_
Result_Code is 0.
