Tips: How to Maintain the ATO Pyranometer Sensor?
- The pyranometer sensor shall be installed in the open air, and there shall be no shelter above the sensor during measurement.
- The sensor connector should face north and be positioned horizontally before fixing.
- Check the glass cover regularly and ensure it is clean.
- Do not remove or loosen the glass cover to avoid affecting the accuracy.
- Please make sure the desiccant has not expired.
- If the desiccant changes color from orange to black, it should be replaced.
- Replacement every six months is recommended. It's best to replace them every six months.
- If there is heavy rain or hail for a long time, it is recommended to install a protective cover.
- The sensitivity should be recalibrated every two years.
