TurfWeather Weather Station
6.9.4 Solar Radiation Sensor Replacement Procedure
This removal and replacement procedure for the solar radiation sensor (pn
14009) requires the main body of the weather station to be opened. The person
replacing this sensor should observe basic electrostatic discharge (ESD)
precautions (described below) to avoid damage to the weather station
electronics inside the main body of the weather station.
Tools Required:
• 1/2-inch wrench
• 5/16-inch wrench
• #2 Phillips screwdriver
1. Solar Radiation Sensor Removal:
a. Follow steps provided in Section 6.9.1, Removing the TurfWeather
Station from a Mast or Pole.

b. Bring the weather station to an enclosed location, preferably near the
host computer, and place it on a flat stable surface with an area of at
least three times the size of the weather station base.
c. Locate the solar radiation sensor on the front of the weather station. It
is the gray plastic knob shaped protrusion on the top, front of the
weather station (FIGURE 6-4). It is stamped on its side with the
words CSI APOGEE PYRC(number).
d. Locate the Phillips head screw on the side of the sensor. Remove the
screw but do not pull on or attempt to remove the sensor at this time.
e. Invert the weather station main body and rest it on a support that
eliminates any stress on the wind speed or wind direction sensors
and/or the rain gage. A rolled bath towel placed in the center of the
main body, next to the rain gage, will generally suit the purpose.
