pressure, it too is correct. The first procedure above generally works
quite well, but for stations at fairly high altitudes (e.g. 5,000 ft. or higher)
it may be more incorrect than at lower altitudes. In such cases
comparisons with other known correct, and nearby at similar altitude,
stations may help. Now that calibration is complete, feel free to change
the pressure units to whatever you like.
Note:
Airport METAR data is often only updated every 10, 15 or even
30 minutes. If you use the information in the procedure above, you may
be looking at pressure data that is out of date by as much as the update
interval. To get best results observe several times and figure out the
update interval and then use two values for the procedure: one taken
immediately after an update, another taken about halfway through the
interval.
Note:
It is also a good idea to observe some more after the calibration
procedure is complete to make sure the numbers are correct
.
2.8 Transmitter ID
This is not a setting you can change. Rather it tells you a number that
identifies the type of outdoor sensor from which sensor data was
received. This is mostly useful for troubleshooting scenarios.
3. ALARM MODE
In normal mode, press
ALARM
key you will enter high alarm mode, and
press
ALARM
key again you will switch to low alarm mode.
When an alarm condition is met, the alarm will sound a loud beep, and
the alarm icon
will flash. The message panel will display a message
appropriate for the alarm condition. Press any button to silence the
alarm beep. The flashing alarm icon will stay until the alarm condition
itself is no longer satisfied (e.g. temperature drops below alarm value,
