This means that the humidity level is below 20%, which corresponds to very dry air. In fact, the recommended humidity level is between 40% and 60% in homes and offices.
On the back of the hygrometer, open the circular compartment by inserting a paper clip or coin into the notch and rotating it. Place the battery under the two tabs by pushing it down.
