When you purchase a digital anemometer it will come with an instruction manual. Read through the instructions carefully before you begin using the device. The instructions will provide you with directions for how to set-up and read your anemometer. The anemometer will come with a battery and you will need to install the battery in the back of the device. Unscrew the battery compartment in the back and place the battery inside. The device will likely have a power button on the front. Once the batteries have been installed, you can turn on the device and begin recording the wind speed. Most digital anemometers will have a variety of different measurement options. For example, you could calculate the wind speed in km/hour, mi/hour, ft/second, ft/minute, and knots. Press the unit button in order to scan through the different measurement options and select the one you would like to use.
