The Ultrasonic Portable Solar wind meter has been designed with a solar panel that makes it a self-powered intrument ; It could work up yo 29 days of continuous operation in the dark and over a year on sleep mode.
Nevertheless, if you have experienced any issues while trying to connect it to your device, we highly recommend you to follow the next steps :
First of all, it is important to double check the battery level of your device. Our Free Anemotracker App will indicate the battery level of your device in its main screen.
Please note you can charge your device either by Led light or natural light. Check which option suits you best.
Option 1 : Led Light ( 30W Power , 5500K Color) charge
We recommend you to have a shallow container and a Led Light (30 W Power, 5500 K Color).
Leave the Ultrasonic Portable Solar wind meter in the shallow container (make sure the solar panel points upwards ), then place a Led light between 3 and 5 fingers above the Ultrasonic Portable Solar wind meter.
You should leave it to charge between 24 and 72 hours, as the time may vary depending on the battery level you wind meter previously had.
After that, check one more time the battery level in Anemotracker App.
Option 2 : Outdoors Charge
Sun strenght may vary depending on location, weather or season. Thus, if you feel natural light is not strength enough for your wind meter, we suggest charging with a Led light (30 W Power, 5500 K Color).
Place your Ultrasonic Portable Solar wind meter outdoors between 24 and 72 hours. Last of all, check the battery level in Anemotracker App.
Calypso Instruments recommends to check the battery level regularly in order to maintain the performance and lifespan of your Ultrasonic wind meter.
