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.
1. Press BAR as necessary to display the current barometric pressure.
2. Press ALARM to display the barometric pressure alarm threshold.
3. Use ENTER to set the change/hour which will cause an alarm.
