FAQ
1. When the temperature and humidity is more accurate?
About 30 minutes after configuration completed, the temp and humidity is closer to actual ambient environment, so the readings are more accurate and reliable.
2. When the temperature and humidity on the screen is not sync with the data in app ?
a)When deviation between temperature display on screen and in app is ± 0.5℃ .
b)When deviation between humidity display on screen and in app is ± 5% .
3 .
a)When device detects the environmental temperature change is 0.5℃ or humidity change is 5%, the temp and humidity will be updated every 2 mins.
b)When device detects the environmental temperature change is < 0.5℃ or humidity change is < 5%, the temp and humidity will be updated every 1 hour.
c) When the backlight is triggered, the temp and humidity on the screen will be locked for 2 mins, if the backlight is triggered again within 2 mins, the temperature and humidity will be locked for no more than 15 mins.
4. Please keep it away from any heat source.
5. If you want to calibrate Fahrenheit, you need calibrate Celsius firstly, then switch to Fahrenheit.
