[. . . ] If the air temperature decreases below the dewpoint (saturation point), the excessive water vapor will condense and fall out in form of dew, fog or rain. 59°F and a relative humidity of 50% the dewpoint will be about 41°F, at 80% humidity about 53. 6°F. At a relative humidity of 100% saturation is reached, i. e. At a dewpoint below freezing the fallout will become frost or snow. Windchill has been introduced for battle planning during World War II. It represents not the real measured but the temperature a person feels in open area under the influence of wind and cold. Windchill is laid out in tables for various temperatures and wind speeds. 46. 4°F and calm winds a person moving at a speed of 13 mph will already feel a windchill temperature of 32°F. Wind Data (LCD Section 3) The current wind direction will be displayed on the LCD compass on the wind section. Press the WIND key to toggle between wind direction as numerical (e. g. 225°) and abbreviated characters (e. g. SW) as well as numerical wind speed display inside the compass circle. 12. Operation keys ALARM key The base station has 8 keys for easy operation. Please refer to the following table for use and function of each key: Further descriptions of the key functions with regard to their immediate range of application can be found in the Programming modes: SET - key - In normal mode to enter the manual basic programming mode - In basic programming mode to select the following setting modes: - LCD contrast setting - Manual time setting (hours/minutes) - 12/24 time format display - Calendar setting (year/month/date) - Time zone setting - °C/°F temperature setting - Wind speed unit setting - Rainfall unit setting - Pressure unit setting - Relative air pressure setting - Weather picture threshold setting - Storm warning setting - Audible storm alarm setting - In setting modes confirmation of the selected values - In alarm modes alarm ON/OFF - In alarm mode to enter programming of alarm values (long pressing) - To exit MIN/MAX modes - Toggle between Absolute and Relative air pressure displays - Toggle between the following current/ maximum/ minimum display modes: - Indoor temperature and humidity - Outdoor temperature and humidity - Outdoor wind chill - Outdoor dew point - Rainfall (24h, 1h, total) To toggle between the following settings: - Wind speed - Wind direction - Wind direction display in degrees MIN/MAX key PLUS (+) key MINUS (-) key PRESSURE key DISPLAY key - In normal mode to enter the alarm programming mode - In alarm programming mode to select the following setting modes: - Time alarm setting - Indoor temperature alarm (high & low) - Outdoor temperature alarm (high & low) - Indoor humidity alarm (high & low) - Outdoor humidity alarm (high & low) - Outdoor wind chill alarm (high & low) - Outdoor dew point alarm (high & low) - Rainfall alarm (24h, 1h) - Pressure alarm (high & low) - Wind speed alarm (high & low) - Wind direction alarm - In setting modes confirmation of the selected values - To exit MIN/MAX modes - To reset general alarm symbol - In normal display mode to toggle between display of MIN/MAX values - To toggle between MIN/MAX values in MIN/MAX mode - To exit any programming mode - In normal display mode to toggle between format of date display, seconds, time alarm and time zone - To increase the values in the setting modes - To exit MIN/MAX modes - In normal display mode to re-enter data learning mode (long pressing for 2 seconds) - In normal display mode to enable/disable the buzzer alarm (long pressing) - To decrease the values in the setting modes - In basic programming mode audible storm alarm ON/OFF - To snooze the alarms off 24 hours when the alarm is sounding - In MIN/MAX modes to reset recorded values and recorded dates and times WIND key 13. Basic Programming Modes 14. MIN/MAX Programming Modes Manual Setting modes The manual setting mode allows the user to change several basic settings, which is done by accessing one mode after the other simply by pressing the SET key. After the final mode, or if no key is pressed for 30 seconds, the manual setting returns to the normal display mode. The manual setting takes the user through the following modes: 1. 8 level LCD contrast setting (default level 5) Manual time setting (hours/minutes) 12/24h time display select (default 12 hours) Calendar setting (year/month/date) Time zone setting from 0 to +12 hrs, -1, -2, -3, AT -4, ET -5, CT -6, MT -7, PT -8, AL -9, HA -10, -11, -12 (default ET -5) Temperature display unit degree Celsius or Fahrenheit (default degree Fahrenheit) Wind speed display units in m/s, km/h, mph, Beaufort, knots (default setting mph) Rainfall display in mm or inch (default setting inch) Air pressure display in hPa or inHg (default setting inHg) Relative air pressure setting from 27. 10 inHg ­ 31. 90 inHg (default 29. 98 inHg) Weather forecast sensitivity setting 6, 9, 12 inHg (default setting 9 inHg) Storm warning sensitivity setting 9, 12, 15, 18, 21, 24, 29 inHg (default 9 inHg) Audible storm alarm On/OFF (default ON) MIN/MAX display Mode The MIN/MAX Mode provides the user with information about the MIN/MAX values of all weather data together with the time and date at which these values were recorded. Entering each MIN/MAX mode In the normal display mode for e. g. the indoor temperature and humidity, press MIN/MAX key to toggle the display between the maximum, minimum and current records. While the maximum or minimum values are shown press the DISPLAY key once to show the time and date that value was received. Now press the MIN/MAX key to toggle from the minimum and maximum readings and the time and dates the records were received are also shown. Still in the MIN/MAX mode (where the time and date for a value are shown), press the DISPLAY key to move through each respective unit as follows: · Indoor temperature (max or min with time and date) · Indoor humidity (max or min with time and date) · Outdoor temperature (max or min with time and date) · Outdoor humidity (max or min with time and date) · Outdoor wind chill (max or min with time and date) · Outdoor dew point (max or min with time and date) · Rainfall 24 hours (max or min with time and date) · Rainfall 1 hour (max or min with time and date) · Rainfall total (max only with time and date) When in any of the above modes, press the MIN/MAX key to toggle between the maximum or minimum values of those records and their respective time and dates will also be shown. For the wind and pressure minimum and maximum readings, the same would apply except that the WIND or PRESSURE keys would be used instead of the DISPLAY KEY.
