Setting the Barometric Pressure Alarm
This section describes the barometric pressure alarm. The barometric pressure
alarm is a special alarm in that it is triggered when the rate of change in the
barometric pressure equals or exceeds the alarm threshold. There are three pos-
sible barometric pressure alarm thresholds: 0.02”, 0.04”, or 0.06” (0.5 mm,
1.0 mm, 1.5 mm or 0.7 hPA, 1.4 hPA, 2.0 hPA). The alarm is triggered whether
the barometric pressure rises or falls. To determine which way the barometric
pressure is moving, check the barometric trend arrow.
