Program Problems
? The barometer graph on the bulletin does not "fill in" completely. Why?
When you first load the bulletin, the only case in which the barometer graph
will fill in completely is when you have data in your database for the span of
the barometer graph (that is, the past six hours). Make sure of the following:
There is data in your database for the span of the barometer graph.
The time and date of the stored barometer data is correct in your database.
The time and date on the PC is correct.
The time and date on the weather station are correct.
? Why do I get strange daily rainfall readings?
Make sure you set total rainfall from the software (see "Set Total Rain" on
page 27). If you change the total rainfall from the weather station, it is very
likely that you will create an odd daily rainfall amount for the interval during
which you make the change. (see "Rainfall" on page 97.)
? I have duplicate records in my database. Why?
If you do not download prior to changing the weather station's time and date
(for a Daylight Savings time change, for example), you may get duplicate
records. Make sure to download before setting time and date. In addition, you
should be aware that the midnight records are duplicated so they appear in
each consecutive day. For example, a midnight record would appear at the
end of the data for November 22 and at the start of the data for November 23.
Using the record editor (see "Edit a Record" on page 61) to change the record
in one day does not change the record in the other day.
? No wind direction reading (or dashes instead of a reading) appears in my database.
First, make certain that you did not select a Weather Wizard II-S or Perception
(neither of which have wind direction) in your station setup (see "Station Con-
fig" on page 19). Otherwise, you should simply be aware that if there is no
wind speed when the direction is being sampled, wind direction is not
recorded. During intervals with very little wind speed, no direction may be
recorded.
Note: Since high wind speed is sampled more often, it is possible to have a high wind speed
but no wind speed or direction.
? My archive memory is empty and I know it should not be. What can I do?
First try using "Set Archive Interval" (page 24) to clear the archive memory
and see if this corrects the problem. You will lose any undownloaded data in
your archive memory, but all of you calibration numbers and alarm settings
will remain intact. If this doesn't work, "reboot" your weather station (that is,
remove all power and restart the station). All data which has not been down-
loaded will be lost. You will also have to reset all settings (barometer, calibra-
tion numbers, etc.).
