Viewing Graphs
Although the graphs available may 
vary for each weather variable, all 
are displayed in the same way.
1.  Select a variable to graph.
2. Press GRAPH to enter Graph Mode. Only the time, date, 
graph, graph icon, selected variable and information 
pertaining to the selected variable are visible. The rest of 
the screen is blank.
Values for the present time and each of the preceding 25 hours are displayed 
in the graph, each hour represented by a dot. The dot at the right end of the 
graph is the value for the current hour. You’ll notice that the dot is blinking. 
The dot at the left end of the graph is the value at least 24 hours ago. 
3. Press the < key and the second dot from the right starts to blink. 
The screen displays the new dot’s value. The time display shows what hour 
is being viewed. 
4. Press the < and > keys to view the variable’s high values for each of the last 
25 hours. 
5. Press the + and - keys to shift the graph’s time span.
If you press the - key, the graph shifts from the current and last 25 hours to 
the current and last 25 days. Each dot represents the high recorded on the 
day shown in the date field. To see the lows recorded in the current and last 
25 days, press HI/LOW. Press the < and > keys to move between days. 
By pressing the - key again, the graph shifts to show the highs of the current 
and last 25 months. As before, use the < and > keys to move between 
months. Press HI/LOW to shift between the highs and lows.
By pressing the - key again, the graph shifts one more time to show the 
highs of the current and last 25 years, but only for Rain Rate, Rain, and ET.
The console beeps when you’ve reached the first or last possible value or 
time span for the graph. Since the console only graphs data collected by the 
station, graphs can only show data collected since the station was installed.
