TurfWeather Weather Station3. MaintenanceProper maintenance of the TurfWeather weather station is essential to obtainaccurate data. Equipment must be in good operating condition, which requiresa program of regular inspection and maintenance. Routine and simplemaintenance can be accomplished by the person in charge of the weatherstation. Inspect the weather station weekly when first installed to get anunderstanding of how often cleaning and inspecting should be performed. Keepthe weather station level for accurate solar radiation and rain measurements.Use the level bubble located on top of weather station for reference. Moredifficult maintenance such as sensor replacement can be accomplished withinstructions included in this manual, or weather station can be sent to CampbellScientific if preferred.3.1 Solar Panel P/N SP5An occasional cleaning of the glass on the solar panel will improve itsefficiency. Use warm mildly soapy water and a clean cloth. Rinse with cleanwater.3.2 Battery Pack P/N 14159The Battery pack is a 12 Volt, 0.8 AHr battery with a special connector. It hasa life expectancy of 3 to 5 years. It is located inside the weather station. It is asealed lead acid battery design, and if it is discharged below 11.0 volts it maybecome damaged and no longer accept a charge regardless of the age of thebattery. PC200W and most weather software will display the weather stationbattery voltage. Typical measurements should be between 12.5 and 13.5 volts.See Section 3.11 ‘Battery Pack Removal and Replacement Procedure’ forinstructions on replacement.3.3 Temperature/Relative Humidity sensor P/N 14144The Temperature/Relative Humidity sensor has a life expectancy of 18 months.The Relative Humidity measurement will begin to drop off as the sensor ages.It is located on the bottom of the weather station inside the slotted cylindershaped protector. Take care not to expose this sensor to overspray frompesticides, fertilizers, etc. Use a soft brush to remove dust and cob webs fromsensor area. See Section 3.12 ‘Temperature/Relative Humidity SensorAssembly Removal and Replacement Procedure’ for instructions onreplacement.3.4 Solar Radiation sensor P/N 14009The Solar Radiation sensor has a life expectancy of approximately 5 years.at anexpected 2% per year degradation rate. This sensor is replaced rather thanrecalibrated. It is the small round sensor located on the opposite end from thewind sensors. Keep this sensor clean using a soft cloth and very mild soapywater, and follow up with a clean damp cloth with water only. See Section3.13 ‘Solar Radiation Sensor Removal and Replacement Procedure’ forinstructions on replacement.34
