T-TOUCH SOLAR E84 METEO (WEATHER) > GLOSSARY Description of function In weather mode, the hands are superimposed to indicate the weather trend. Explanations Weather changes are related to variations in atmospheric pressure. When atmospheric pressure increases the sky clears. The area is then referred to as a "high pressure" area or "anticyclone" (A). When atmospheric pressure decreases the sky clouds over. The area is then referred to as a "low pressure" area or "depression" (D). The T-TOUCH SOLAR E84 watch measures these pressure variations and indicates the weather trend with the hands, which can adopt the following 7 positions according to the weather developments: - 6': Big pressure drop, rapid deterioration - 4': Moderate pressure drop, probable deterioration - 2': Small pressure drop, probable slight deterioration 12 o'clock: No notable weather change + 2': Slight pressure rise, probable slight improvement + 4': Moderate pressure rise, probable improvement + 6': Big pressure rise, rapid improvement The T-TOUCH SOLAR E84 program takes account of atmospheric pressure variation over the last 6 hours to calculate the trend to indicate. Furthermore, the pressure variation caused by a rapid change in altitude is detected by the watch and compensated for automatically. So it only has a minimal impact on the barometric trend. The T-TOUCH SOLAR E84 digital display indicates the absolute and relative atmospheric pressure values in hectoPascals [hPa]. Absolute atmospheric pressure is the actual pressure at the time and place of measurement, and cannot be altered. Relative pressure is a value relative to sea level, based on local absolute atmospheric pressure. Barometers and weather charts show relative pressure values. The relative pressure value depends on the climate zone set, and can be preset on the watch. The relative pressure presetting is in line with the altitude. Characteristics of function Measurement range: absolute pressure: 300 hPa to 1100 hPa relative pressure: 950 hPa to 1100 hPa Accuracy: absolute pressure: ± 3 hPa relative pressure: varies with altimeter Resolution: 1 hPa Unit conversion: 1 hectoPascal [hPa] = 1 millibar [mb] ALTIMETER > READING The altitude is displayed on the digital screen for 10 hours continuously. After 10 hours, altimeter mode is deactivated, and the date is displayed. The altitude unit system for displaying the altitude (m or ft) depends on the m/ft unit configuration in the options (see page 8). 1 sec.
