Pressure Difference Measurement Sub Mode; How To Start The Pressure Difference Measurement - Suunto Mariner User Manual

In the Barometer mode (Fig. 14):
• Field 1 displays the current temperature.
• Field 2 displays the current absolute atmospheric pressure.
• Field 3 displays the current time.
• The Outer Circumference graphically displays the atmospheric pressure over 100 millibars or 1 inHg where one
complete circle is equivalent to 100 mbar/1 inHg, depending on the unit of measure chosen.
Note: The absolute pressure is the actual pressure in any location at any given time. Where as, sea level pressure is
the corresponding pressure at sea level.

4.1 PRESSURE DIFFERENCE MEASUREMENT SUB MODE

In the Barometer mode, PRESS the [Select] button once to enter this sub mode.
In the Pressure Difference Measurement sub mode (Fig. 15):
• Field 1 displays the change in temperature.
• Field 2 displays the change in atmospheric pressure.
• Field 3 displays the current time; to the left of the time is the text "differ".
• The Outer Circumference graphically displays the change in pressure where one full circle equals 100 mbars or 1
inHg.
This sub mode does continue in the background and allows the user to move to other modes and at the user's convenience
can return to this sub mode to show the current reading.

4.1.1 How to Start the Pressure Difference Measurement
