6.1.2.2 Solar Panel
Occasionally clean the glass on the solar panel to improve its efficiency. Use
warm mildly soapy water and a clean cloth. Rinse with clean water.
6.1.3 Desiccant
Humidity is monitored inside the ET107 enclosure using the Elan HM2000 RH
sensor that is incorporated in the enclosure. Change the desiccant packs when
the enclosure RH exceeds 50%. The enclosure RH sensor should be changed
approximately every five years.
Desiccant packs may be ordered in quantity of 20 individually sealed packs at a
time or by the individual pack.
6.1.4 Sensor Maintenance
All factory repairs and recalibrations require a returned material
authorization (RMA) and completion of the “Declaration of
Hazardous Material and Decontamination” form. Refer to the
page at the beginning of this manual for more
information.
Perform sensor maintenance at regular intervals, depending on the desired
accuracy and the conditions of use. A suggested maintenance schedule is outlined
below. Appendix
(p. B-1)
, provides an example of a
maintenance log file for one year of station use.
1 week
•
Check the rain gage screen and funnel for debris and level.
1 month
•
Check the solar radiation sensor (pyranometer) for level and
contamination. Gently clean with blast of dry air, soft camel hair
brush, or clean water if needed.
Handle the pyranometer carefully when cleaning. Be careful
not to scratch the surface of the sensor.
•
Do a visual/audio inspection of the 034B-ET anemometer at low wind
speeds. Worn bearings can cause the wind cups to spin in an uneven
manner and/or make a grinding sound.
•
Check the WindSonic1-ET for contamination. If needed, gently clean
the WindSonic1 with a cloth and mild detergent.
When cleaning the WindSonic1, do not use solvents and
avoid scratching the sensor.
