Collins, Colorado and transmits the exact time signal continuously throughout the United States at 60 kHz. [. . . ] The Absolute setting gives a true and real-time air pressure reading (at the users location) that cannot be manually calibrated. However the Relative air pressure setting must be manually programmed to suit the users needs. Relative air pressure is measure in relation to sea level and is the standard form of measure. You can retrieve the Relative air pressure from your local weather service. Absolute air pressure decreases by about . 01 inHg for every 10 feet in altitude. In higher altitudes (above 6, 500 feet) this effect is less noticeable. The WS-7059SU will measure absolute pressure reliably up to 7, 500 feet. Press and release the "CH/+" button to toggle through the Absolute and Relative options until you reach the desired setting. Press and release the "MODE/SET" button to confirm and advance to the manual setting of the Relative air pressure. 3. 12 K. The numerals in the pressure LCD will now be flashing (only for relative air pressure) 2. Press and release the "CH/+" to increase the relative air pressure. Press and release the "MODE/SET" button to confirm. The manual set up is now complete. 13 II. FEATURES OF THE WS-7059SU A. WEATHER FORECAST The weather forecast feature is estimated to be 75% accurate. By adjusting the sensitivity setting you can achieve a better accuracy of forecast. The weather forecast is based solely upon the change of air pressure over time. In areas where the weather is not affected by the change of air pressure this feature will be less accurate. Please note that this is based off of the last 30 hours so your unit will need to be activated for this amount of time to have the sufficient data for forecasting. WEATHER ICONS There are 3 possible weather icons that will be displayed in the tendency LCD: Sunny - Indicates that the weather is expected to improve (not that the weather will be sunny). Sun with Clouds - Indicates that the weather is expected to be fair (not that the weather will be sunny with clouds). Clouds with rain - Indicates that the weather is expected to get worse (not that the weather will be rainy). The weather icons change when the unit detects a change in air pressure. The icons change in order, from "sunny" to "sun with clouds" to "clouds with rain". Note: When you are done viewing the minimum or maximum data press either the "IN/OUT" or the "MIN/MAX/RESET" button to exit, or wait 20 seconds for the unit to return automatically to the current settings. 16 1. 2. 3.
