averaging period is less than the logging period the average
logged will be for a period of time at the end of the logging
period equal to the averaging period. If the averaging period is
longer than the logging period then the data stored will be a
running average that reaches back in to previous logging
periods.
Enter the number of minutes desired and press “Enter”.
Logging Period
Press 4. Logging Period. The menu will ask you to enter a
number between 1 and 60 minutes. Enter your selection and
press, “enter”.
The number of days of data that can be stored in the memory
is a function of the logging period, the magnitude of the data
reported and the number of sensors activated. With the
standard complement of sensors (wind speed, wind direction,
temperature, relative humidity, barometric pressure and
precipitation) the memory will fill in about 45 days if the
logging period is fifteen minutes. Once the memory is full it
“wraps” that is it continuously over-writes the oldest data in
the memory with new data.
Date & Time
Press 5, Date & Time. The menu will direct you to enter the
current date in the following format:
[MM/DD/YYYY]. When the proper date has been entered
press, “Enter”. The menu will direct you to enter the current
time in 24 hour format [HH:MM]. When the proper time has
been entered press, “Enter”.
Add or Remove Sensors
Press 6. Add or remove sensors. The menu displays the
following warning, “You must off-load data before changing
sensor configuration. Logging memory will be automatically
cleared if changes are made. Do you want to continue/ [Y or
N]:”. Enter, “Y” and the Weather Port WMS-16 Station
Sensor configuration will appear. If all of the sensors that you
intend to use are shown as being configured then press “Q”
and “Enter”. If you wish to add or delete a sensor then Press
“A”: for add or “D” for delete and follow the instructions
presented on the menu.
Power Outage Warning
The data entered using the Station Setup procedure is
automatically stored in the system’s memory. The data will
remain in tact even if there is a power outage. All data
collected will also remain in tact if there is a power outage.
However, the system will not report or log data during periods
of power outage. When reviewing data logs, gaps in the store
data can be attributed to power outages.
Current Observations
Press “2” at the main menu to access the most frequently used
screens. These are the current observations screens, and they
are shown in Figure 4 (Main Text Display Screen) and Figure
7 (Row and Column Display Screen). The current
observations screens show the values currently being
measured by the station’s sensors. These values are updated
every five seconds and provide a running record of weather
conditions. The topmost line on the line on the Main Text
Display Screen shows the station name, current date, and time.
