• Clean the Gill Radiation Shield by removing the two Phillips screws
holding it to the sensor arm. Gently pull the sensor out of the shield.
Clean the gill shield using warm mildly soapy water. Rinse with
clean water and allow the shield to dry before putting it back on the
sensor arm.
• If necessary clean the white filter element on the end of the
temp/RH sensor. To clean the filter, unscrew it from off the end of
the sensor and put it in a cup of CLEAN DISTILLED WATER. Use
no soap. Agitate the filter in the cup of water. Remove the filter and
allow to air dry before putting it back on the end of the sensor.

• Replace wind speed (anemometer) bearings. To send the sensor to
Campbell Scientific for bearing replacement call for Return Material
Authorization number or contact Campbell Scientific for bearing
cost to replace bearings in the field.
• Replace wind speed (anemometer) reed switch if needed. To send
the sensor to Campbell Scientific for reed switch replacement call
for Return Material Authorization number or contact Campbell
Scientific for reed switch cost to replace reed switch in the field.
• Check calibration of the CS500 temp/RH probe. Sensor will tend to
drift up over time giving readings higher then 100%. Replace RH
chip (item# 9598) if necessary.
• Replace desiccant in enclosure housing as needed.

• Send the solar radiation sensor (pyranometer) to Campbell
Scientific for calibration. Call Campbell Scientific for Return Material
Authorization number. Sensor cannot be calibrated in the field.
(Some users recommend calibrating this sensor on a yearly basis.)
• Note: Sensor could be away for as long as a month and a half to be
calibrated. Best to send sensor in during an off part of the growing
season or when solar radiation is not vital.
• Replace wind direction potentiometer if needed. To send the sensor
to Campbell Scientific for potentiometer replacement call for Return
Material Authorization number or contact Campbell Scientific for
potentiometer cost to replace potentiometer in the field.
• Replace enclosure gasket if necessary. Enclosure can be sent in to
Campbell Scientific for gasket replacement – call for Return
