SECTION 2. MAINTENANCE
2-2
2.2.3 TEMPERATURE AND RELATIVE
HUMIDITY PROBE
Visually inspect the Temperature/Relative
Humidity Sensor in extreme weather conditions,
and clean if necessary. (Refer to 2-3 month
section for cleaning procedures).
2.2.4 WIND SPEED AND DIRECTION SENSORS
Spin the wind direction and wind speed sensors
to be sure they move freely.
CAUTION!: DO NOT use WD-40 or other
lubricants on the bearings.
2.2.5 MOISTURE
The enclosure should have desiccant in it to
absorb moisture. Moisture on the wiring panel
will cause problems with voltage supplies to the
datalogger.
2.3 2 TO 3 MONTH
2.3.1 VISUALLY INSPECT AND CLEAN THE
SOLAR SENSOR.
Examine the Solar Sensor, and clean if
necessary. The sensor can be cleaned with a
blast of clean, dry, air, a soft bristle, camel hair
brush, or some water. BE CAREFUL NOT TO
SCRATCH THE SURFACE OF THE SENSOR.
In extreme and dusty environmental conditions
it may be necessary to inspect and clean the
sensor on a monthly basis. Check to make
sure that the drain hole next to the surface of
the sensor is clean from debris. Handle the
sensor carefully when cleaning.
FIGURE 2.3-1 6910 Solar Sensor
NOTE: There are two types of
Temperature/Relative Humidity Sensors
which you may have. Refer to the cleaning
procedures for your particular system
below:
2.3.2 TEMPERATURE/RELATIVE HUMIDITY
SYSTEMS SHIPPED AFTER JANUARY 1, 1991
Part Number 6575 Temperature/Relative
Humidity probe requires minimal maintenance
unless there is physical damage or repeated
condensation on the HMP35C Probe. Check
monthly to make sure the radiation shield and
end cap on the sensor are free from debris.
Check the sensor end cap by removing the
sensor from the radiation shield. The sensor is
fastened by a plastic compression screw which
screws into the shield. Loosen the screw
around the sensor and pull the sensor out of the
shield. Check the screen for debris and clean
by removing dirt or dust with a soft brush. If the
end cap is still dirty, contact your Toro
distributor to send a replacement end cap.

Humidity Probe
2.3.3 TEMPERATURE/RELATIVE HUMIDITY
(SYSTEMS SHIPPED BEFORE JANUARY 1, 1991)
Visually inspect Temperature/Relative Humidity
Sensor, and clean if necessary.
To inspect and clean the sensor, remove the
sensor from the radiation shield. The sensor is
held inside the radiation shield by two plastic
retainers on the bottom of the shield. Loosen
the screws holding the retainers and rotate the
two retainers to one side so the sensor can be
removed.
