3.2.2 Units of Measure
The units for each sensor are assigned to that sensor at the time the sensor is installed
as part of the sensor selection and installation process. The units available for the
various sensors are as follows:
Wind speed: kph, KT, m/s, mph
Temperature:
/
F,
/
C,
/
K,
/
R
Pressure: in Hg, hPa
Precipitation: in, mm
3.2.3 Averaging Period
Press "3", Averaging period. The averaging period is user selectable over the range
from 1 minute to 60 minutes. The stored data will be the average of the data measured
at five-second intervals over the user selected averaging period. If the averaging period
is less than the logging interval, the average logged will be for a period of time at the
end of the logging interval equal to the averaging period. If the averaging period is
longer than the logging interval then the data stored will be a running average that
reaches back into previous logging intervals. The averaging period is usually set to 15
minutes or the same as the logging interval.
Enter the number of minutes desired and press "Enter".
3.2.4 Logging Interval
Press "4", Logging interval. The menu will ask you to enter a number between 1 and 60
minutes. The logging interval is usually set to 15 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 interval, 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 interval is 15 minutes. Once the memory is full it
“wraps,” that is it continuously over-writes the oldest data in the memory with new data.
3.2.5 Date & Time
Press "2", 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".
