Maintaining UV and Solar Radiation Sensors on Vantage Pro Plus
Make every effort to avoid touching the small white diffusers at the top of the
sensors.
Any skin oil will reduce the sensitivity of the sensors. For accurate
readings, clean the diffusers periodically using ethyl alcohol on a soft cloth
(NOT rubbing alcohol).
Due to the sensitivity of ultraviolet and solar radiation sensors it is common
practice for manufacturers to recommend re-calibration after a period of time.
Here at Davis Instruments we have seen less than 2% drift per year on the
readings from these sensors. For applications demanding higher accuracy,
however, the sensors should be calibrated once every year.
Contact Technical Support (510) 732-7814 about returning your sensor for cali-
bration.
Cleaning Rain Collector
For accuracy, thoroughly clean the rain collector several times a year.
Note: Please be aware that cleaning the tipping bucket may cause false rain readings to occur.
1. Separate the cone from the base by turning it counter-clockwise.
2. Use soapy water and a soft cloth to remove any debris from the cone, cone screen,
and tipping bucket. Watch out for spiders — they seem to like rain collectors!
3. Use pipe cleaners to clear the funnel hole in the cone and drain screens in the base.
4. When all parts are clean, rinse with clear water.
5. Re-attach the cone and replace the debris screen.
