Reading the Barometric Pressure and Temperature

Reading the Barometric Pressure and Temperature

Barometric Pressure
  • Barometric pressure is displayed in units of 1 hPa (or 0.05 inHg).
  • The displayed barometric pressure value changes to - - - if a measured barometric pressure falls outside the range of 260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg). The barometric pressure value will reappear as soon as the measured barometric pressure is within the allowable range.

Temperature
  • Temperature is displayed in units of 0.1°C (or 0.2°F).
  • The displayed temperature value changes to - - - °C (or °F) if a measured temperature falls outside the range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The temperature value will reappear as soon as the measured temperature is within the allowable range.
Display Units

You can select either hectopascals (hPa) or inchesHg (inHg) as the display unit for the measured barometric pressure, and Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature value. See “To specify temperature, barometric pressure, and altitude display units” (page E-35).
