HYGROMETER CALIBRATION
If the humidity reading on the device seems incorrect, it can be calibrated using a known humidity and temperature reference.
- Wrap the hygrometer in a damp towel,
- keep it for about 1 hour,
- then, after removing it, adjust the pointer to 100% using the adjustment screw.
Calibration alone is not enough for the hygrometer to show correct readings. The device should be installed at a height of about 1.6 m. If its size allows, it is best to place it 1.5–2 meters away from doors, windows, and a stone-loaded stove. Nearby sources of heat or cold may distort the readings.
