The WEATHERmeter has a built-in compass (magnetometer). That means you don't have to point your phone in any particular direction - just point the meter into the wind!
Does your compass seem off? Please see these notes on calibration.
Even with calibration, the compass direction from the meter will not be as accurate as most smartphones. Smartphones have other sensors to help determine the direction (GPS, accelerometer) and can often auto-calibrate.
In cases where you want or need a more accurate direction reading, the Wind & Weather Meter app has an option in the settings to use your phone's compass instead.
If you are using your phone's compass direction remember you will need to point the phone in the direction the winds are coming from. You can use the audio jack mount to align the WEATHERmeter and your phone perfectly. However, the meter can be up to 15 degrees off-axis and still measure winds accurately.
There is a replaceable CR2450 battery in the WEATHERmeter. It is designed to provide approximately 500 hours of use on low power and 300 on high power, which should be many years of normal sampling. If your battery dies you can easily replace it. Just peel off the silicone "skin" to reveal a battery door. Slide the battery door open, replace the battery, and put the skin back on. See Battery Replacement for more info and an instructional video.
