Measuring unit: 1 m (5 ft.) Hand indication graph of altitude differential Manual memory measurements (up to 14 records, each including altitude, date, time) Auto log data (High/low altitudes, cumulative ascent and descent) Others: Relative altitude readings (±100 m /±1000 m), selectable measurement interval: 5 seconds or 2 minutes (1 second for first 3 minutes only) *Changeover between meters (m) and feet (ft) Barometer Measuring range: 260 to 1,100 hPa (7.65 to 32.45 inHg) Measuring unit: 1 hPa (0.05 inHg) Hand indication of pressure differential (±10 hPa) Atmospheric pressure tendency graph (last 20 hours or last 56 hours) Barometric pressure tendency information alarm (beep and arrow indicates significant changes in pressure) The atmospheric pressure tendency graph can show the last 20 minutes or last 56 minutes of measurements. The hand indication of pressure differential shows values in units of ±1 hPa. *Changeover between hPa and inHg Digital compass Measures and displays direction as one of 16 points Measuring range: 0 to 359° Measuring unit: 1° 60 seconds continuous measurement Hand indication of north Magnetic declination correction Direction calibration (2-point calibration, figure eight calibration, auto calibration) Thermometer Measuring range: -10 to 60℃ (14 to 140℉) Measuring unit: 0.1℃ (0.2℉) *Changeover between Celsius (℃) and Fahrenheit (℉)
