Module No. 5682

Checking the Change in Barometric Pressure between Two Readings

When you perform the procedure below in the Barometer Mode, the second hand indicates the difference between the current barometric pressure measurement and the last auto measurement value (taken at two-hour intervals).

  1. Enter the Barometer Mode.

    2. Navigating Between Modes

  2. Press (D).

    3. The second hand indicates the barometric pressure differential (Pressure Differential Indicator).

    Example: Barometric pressure differential of -3 hPa (approximately -0.09 inHg)

Note

You can toggle between the two second hand functions by pressing (D).

Checking the Current Barometric Pressure

The second hand points to hpa_Over_ver2021 (over) if the current barometric pressure differential is greater than +10 hPa (0.3 inHg), or hpa_Under_ver2021 (under) if it is less than -10 hPa (-0.3 inHg).

A reading that is outside the allowable measurement range of 260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg), or any measurement error will cause the second hand to move to 9 o’clock.
