How do you use a temperature hygrometer?
For digital hygrometers, you will only have to place the instrument at about 3.3 feet (one meter) from the ground. Let the device work for at least three minutes so it can adequately detect the temperature of the air. You do not have to perform any other calculations because the instrument will do it for you.
How do I adjust the humidity on my HTC One?

Place a zip lock bag flat on a flat surface. Place the cap inside the bag with the hygrometer. Seal the bag and wait 4 hours. Through the bag, push and hold the green button until the hygrometer resets itself to 75.
How do I know if my hygrometer is working?
Dampen a towel (not dripping wet, but good and damp), then wrap the hygrometer in the towel for 30 to 45 minutes. Then unwrap it and read the humidity (quickly). If your hygrometer is perfectly calibrated (few are) it will be reading exactly 100% humidity.

How do you read a hygrometer chart?
Read the hydrometer scale at the lowest point of the surface of the liquid. The most common scale on hydrometers is specific gravity, in which pure water measures 1.000. If you get a higher reading, your liquid is heavier than water, and if you get a lower reading, it’s lighter.
