Measures barometric pressure and graphically displays the barometric trend. Displays temperature and time of day/date. Forecasting indicators show weather conditions for the next 12-hours using symbols for sunny, cloudy, and rainy. Clock shows time in AM/PM or 24-hour format and date. Barometric range: 23.62 to 31.01 inHg / 800 to 1050 mbar. Resolution: 0.063 inHg / 1 mbar. Accuracy: ±6 mb (890 to 1020 mb); otherwise ±10 mb. Temperature range: -9 to 70°C (-22 to 158°F). Resolution: 0.5°. Accuracy: ±1°C (between 32 to 104°F/0 to 40°C); otherwise ±2°C.
