9. Maintenance and Troubleshooting
For all factory repairs, customers must get an RMA. Customers
must also properly fill out a “Declaration of Hazardous Material
and Decontamination” form and comply with the requirements
specified in it. Refer to the Assistance page at the front of this
manual for more information.
9.1 Troubleshooting
Symptom: Temperature is NAN, –INF, –9999, –273
Verify the red wire is connected to the correct single-ended analog input
channel as specified by the measurement instruction, the black wire is
connected to the switched excitation channel as specified by the measurement
instruction, and the purple wire is connected to datalogger ground.
Symptom: Incorrect Temperature
Verify the multiplier and offset parameters are correct for the desired units
(Section 7.6 , Datalogger Programming
(p. 11)
). Check the cable for signs of
damage and possible moisture intrusion.
If the 110PV needs to be sent to Campbell Scientific for
repairs, remember that the probe must be heated to 70 to
80 °C before removing it from the measurement surface.
Prying the probe off without heating it will likely damage both
the probe and the PV module.
Symptom: Unstable Temperature
Try using the 60 or 50 Hz integration options, and/or increasing the settling
time. Make sure the clear shield wire is connected to datalogger ground, and
the datalogger is properly grounded.
9.2 Maintenance
The 110PV probe requires minimal maintenance. Periodically check cabling
for proper connections, signs of damage, and possible moisture intrusion.
