4. Press + repeatedly to display the minimum values for: outdoor humidity, outdoor temperature, wind chill
temperature, dew point, indoor humidity, indoor temperature.
5. Press HISTORY to return to normal mode.
Resetting a minimum or maximum
To reset a minimum or maximum:
1. Enter minimum or maximum reading mode and press + to display the value that you want to reset.
2. Press and hold SET for 3 seconds.
3. Repeat for any other minimum or maximum value that you want to reset.
4. Press HISTORY to return to normal mode.
8. Resetting
To reset the weather station to the factory defaults, press and hold the + key for 20 seconds.

10. Calibration
For accurate measurements, you can calibrate wind speed, temperature, humidity, and rainfall measurements
using calibration tools (not incl.).
To enter calibration mode, proceed as follows:
1. From normal mode, press and hold HISTORY for 8 seconds.
The station is now in calibration mode. The wind factor digits on the display flash.
2. Press SET to go to the next setting; use the + or MIN/MAX keys to change the values.
3. To exit the calibration mode, press HISTORY.
See below for a description of each calibration setting.
Wind speed calibration
The default wind speed calibration setting is 1.0. The adjustment factor ranges from 0.75 to 1.25. You can set it
in 0.01 increments.
Wind speed is the most sensitive to installation constraints. The following factors influence wind speed
measurement:

the location of the weather station: proximity of buildings, trees, or other obstructions
 the wear of the moving parts of the anemometer.
To calibrate the wind speed, we recommend using a calibrated wind meter (not incl.) and a constant-speed,
high-speed fan (not incl.).
Temperature calibration
You can calibrate indoor and outdoor temperature measurements.
The following factors influence temperature measurement:

proximity of heat sources, such as buildings, the ground…
 installation in direct sunlight without proper shielding in hot weather environments.
To calibrate the temperature, we recommend using a mercury or alcohol thermometer (not incl.). Do not use
bi-metal (dial) or other digital thermometers, as they have their own error margin. Do not use a local weather
station in your area (difference in location, timing of updates, and possible calibration errors).
To calibrate the temperature, proceed as follows:
1. Place the temperature sensor in a shaded, controlled environment.
2. Place the thermometer right next to it.
