110PV Surface Temperature Probe
7. Maintenance, Removal, and Calibration
7.1 Maintenance
The 110PV probe requires minimal maintenance. Periodically check cabling
for proper connections, signs of damage, and possible moisture intrusion.
7.2 Removal from Measurement Surface
Remove the 110PV from the measurement surface by heating the probe to 70°
to 80°C, and then pulling it off.
Prying the 110PV off without heating it will likely damage
both the probe and PV module.
CAUTION
7.3 Recalibrations/Repairs
For all factory repairs and recalibrations, customers must get returned materials
authorization number (RMA). Customers must also properly fill out a
“Declaration of Hazardous Material and Decontamination” form, and comply
with the requirements specified within. Refer to the “Assistance” page at the
front of this manual for more information.
8. 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 5). 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.
CAUTION
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.
