Buenas

¿Alguien sabe como poner el índice UV a cero durante la noche?. La cuestión es que me marca 0.8 de índice UV en la consola. O estoy ciego o por la noche no sale el sol... 

Un saludo

Repasa el jack de conexión en la caja de la ISS.

Creo que en la página de Davisnet se hablaba de limpiarlos y ocasionalmente recalibrarlos en fábrica.

Maintaining the Sensor
For the most accurate readings, clean the diffuser after mounting, and then periodically.
Use ethyl alcohol (not rubbing alcohol).
Due to the sensitivity of ultraviolet and solar radiation sensors, it is common  practice for manufacturers to recommend recalibration after a period of time. Here at Davis Instruments, we have seen approximately 2% drift per year on the readings from these sensors. For applications demanding higher accuracy, the sensors should be calibrated once every year.

Sensor Troubleshooting
If encountering sensor problems, carefully check all cable connections from the sensor to the console. Cable connections account for a large portion of the potential problems.
Connections should be firmly seated in the jacks and plugged in straight. Try jiggling the cable while looking at the display. If a reading appears intermittently on the display as you jiggle the cable, the connection is faulty.

Ok, haré eso a ver que tal

Gracias

Vale, ya lo he hecho, lo he limpiado y ahora si que da 0.0 ya que no hay nada de sol

Gracias
