"Product description Why the screen turns black after the weather station is connected to the power supply？ A: When the kalawen weather station is connected to the power supply, the WWVB function (automatic calibration time) will be activated, and the screen will go black for about seven minutes.

Why can't the screen stay bright all the time? A:When the weather station uses battery power, the screen will turn black after 15 seconds in order to save power.

If you want the screen to stay bright, please use the adapter alone for power supply.

(Do not use battery and adapter at the same time) Why is the temperature and humidity of the sensor inconsistent with that of the host? Pressure is not accurate? A: The internal parts of the host are completely wrapped and cannot directly contact the air, so there will be a certain deviation."
