9. Troubleshooting and
maintenance
NOTE:
All factory repairs and recalibrations require a returned material authorization (RMA) and
completion of the “Statement of Product Cleanliness and Decontamination” form. Refer to
the
page at the end of this manual for more information.
9.1 Troubleshooting
Symptom: Pressure and temperature values are returned as NAN.
l
Check that the card is inserted fully in its socket and in the correct orientation (see
(p. 31)).
l
Verify the white wire is connected to the terminal specified by the
SDI12Recorder()
instruction.
l
Verify the red wire is connected to a 12V terminal and the black wire is connected to the G
terminal.
l
Use a digital voltage meter to check the voltage to the sensor. If a switched 12V terminal is
used, temporarily connect the red wire to a 12V terminal (non-switched) for test purposes.
l
Verify the BaroVUE 10 SDI-12 address matches the address entered for the
SDI12Recorder()
instruction. The default address is 0. The address can be verified or
changed with the commands described in
9.2 Maintenance
The BaroVUE 10 calculates information about the quality of the measurement (see
(p. 17)). The quality metric gives information about the reliability of the data; a poor quality metric
may mean the data is unreliable and the device should be sent to the factory for calibration.
However, it is recommended that the sensor card is sent to Campbell Scientific for calibration
every 12 months regardless of the value of the quality metric. Refer to
for more
information.
