Recommended Maintenance of third party devices

Some of the sensors included in the weather station require either replacement or re-calibration after
deployment.
A89WS-PY1: LI-COR recommends that the LI-200SZ Pyranometers be calibrated every two years to
maintain the sensor accuracy. This requires the device to be sent to LI-COR (402) 467-3576 for
recalibration.
A89WS-TH1: Veris recommends that the humidity element on the HO2XMSTA1-O2
Temperature/Humidity sensors be tested every year and replaced accordingly. This element is field-
replaceable, and can be obtained by contacting Veris Industries (503) 598-4564 directly.
A89WS-AN1,AN2: NovaLynx recommends that you apply several drops of light weight (3-in-1)
machine oil or lightly spray WD40 onto the anemometer bearing located just below the cups. Always
look at the wind vane alignment to North. If the alignment is critical, do the check with a compass.
Make corrections to the alignment as needed. Always check the alignment after a severe storm with
high velocity winds.
