Section 6. Maintenance and Troubleshooting
6.1.4 Sensor Maintenance
Sensor maintenance should be performed at regular intervals, depending on the
desired accuracy and the conditions of use. A suggested maintenance schedule is outlined below.
1 week
•Check the pyranometer for level and contamination. Gently clean, if needed.
•Visually inspect the wind sensors and radiation shield.
1 month
•Check the rain gage funnel for debris and level.
•Do a visual/audio inspection of the anemometer at low wind speeds.
•Check the filter of the temperature/humidity sensor for contamination.
General Maintenance
•An occasional cleaning of the glass on the solar panel will improve its efficiency.
•Check sensor leads and cables for cracking, deterioration, proper routing, and strain relief.
•Check the tripod or tower for structural damage, proper alignment, and for level/plumb.
6 months
•Clean the temperature/humidity sensor.
•Clean the Gill Radiation Shield.
1 year
•Replace anemometer bearings.
•Calibrate the rain gage.
•Calibrate the HMP45C probe.
2 years
•Calibrate the pyranometer (some users suggest yearly).
•Calibrate the HMP45C temperature/humidity sensor.
•Replace the wind vane potentiometer and bearings.
4 - 5 years
•Replace sensor cables as required.
Rain Gage Calibration Check
1.Secure a metal can that will hold at least one quart of water.
