To use a hygrometer, first ensure it is calibrated properly, if necessary. Place the hygrometer in the area where you want to measure humidity, allowing it to stabilize for a few minutes. Read the humidity level displayed on the hygrometer, and record the measurement if needed. For digital hygrometers, simply turn it on, while analog models may require you to check the needle or dial.
