The display will cycle through the possible entries: 0.02, 0.04, and 0.06 inches
(0.5, 1.0 and 1.5 mm or 0.7, 1.4 or 2.0 mb). The entry represents a change in baro-
metric pressure over the course of approximately one hour. Therefore, setting the
alarm to 0.04 inches means that the alarm will sound if the barometric pressure
changes (rises or falls) by 0.04 inches (1 mm or 1.4 mb) in any hour long period.
This alarm is checked approximately every 15 minutes.

cleared. The word ALARM and the function triggering the alarm remains on
the display until alarm conditions are no longer met or the alarm is cleared.
