Figure 7 Row and Column Presentation of Current Data
Weather Trends
The current observations text screen displays several weather features in addition to the current sensor readings. These values show the extent to which the measured parameters have varied over an extended period:
Peak wind speed, with the highest value recorded during the past 10 minutes displayed
The high and low temperatures for the day (based on measurements taken since 12 midnight), and the changes in temperature in the past hour.
The high and low barometric pressure for the day (based on measurements taken since 12 midnight), and the change in barometric pressure over the past three hours.
The change in relative humidity over the past hour.
Three values for precipitation accumulation, with totals for the past logging period, for the current day (rainfall since 12
Caution; If power is interrupted the stored trend values, will be cleaned, and reset to the current, starting day & time. All three precipitation totals will go to 00.00 and today’s hi/low will become the current temperature.

After selecting “3” from the main menu, specify the number of hours of data to be retrieved.
The data will be displayed in the format shown in Figure 8. The data is organized as follows:
The top line shows date and time at the right margin.
The weather data is organized into columns, with an abbreviation for each parameter and the units of measure used (selected through the setup menu) shown at the top of the column.
TIME- The time at which the data was logged; this time is based on the time that was set through the setup procedure (see Station Setup): in military time
WS- Wind speed: in miles per hour or meters per second.
WD- Wind direction in degrees.
PK- Peak wind speed: in miles per hour or meters per second. This is the highest wind speed measured over any two second interval.
BP- Barometric pressure: in inches of mercury or millibars. This is the average pressure measured during the logging period.
T1- Temperature measured by the temperature/RH probe: in degrees Fahrenheit or degrees Celsius.
RH- relative humidity measured by the temperature/RH probe: in percent
T2- Temperature measured by an auxiliary probe (if used); in degrees Fahrenheit or degrees Celsius.
SR- Solar radiation; in watts per square meter.
RF- Precipitation (rainfall) accumulated during the logging period: in inches or millimeters.
The logging interval is selected by the user. The range is one minute to sixty minutes. A maximum of 18 records can be displayed on a single screen, so if more than 18 periods were requested the data will be continued on subsequent screens.
