FEATURES & OPERATIONS
I) BAR GRAPH
The bar graph displays the rainfall history. As indicated by the appearance of the
word “HISTORY” at the left-central area of the LCD screen.
The horizontal axis measures the past time periods, with “0” representing the current
day, week, or month and “6” representing the oldest information (6 days ago, 6
weeks ago, or 6 months ago). The graph reads from right to left.
The vertical axis measures the rainfall in inches. The normal (default) measurement
scale is {0, 0.1, 0.2, 0.3, 0.4, 0.5, 1, 2, 3, 4, 5, 10 inches}. If, within any selected
time period (1 day, 1 week, 1 month), rainfall exceeds 20 inches the measurement
scale automatically changes to {0, 1, 2, 3, 4, 5, 10, 20, 30, 40, 50, 100 inches}.
The bar graph will display the rainfall history either by day, week, or month. To
select which to display:
1. Press the HISTORY/+ button. The “DAILY” icon will shift and become the
“WEEKLY” icon (appearing across the central position of the LCD).
2. Press the HISTORY/+ button to toggle through the “WEEKLY,”
“MONTHLY,” and “DAILY” icons.
If “DAILY” is selected, the graph will display the rainfall history for the
past 6 days. The information that is displayed in column “0” (the right
column) is renewed daily at midnight, and the information contained in the
columns is shifted to the left. If “WEEKLY” is selected, the graph will
display the rainfall history for the past 6 weeks. The information that is
displayed in column “0” is renewed every Monday at midnight, and the
information contained in the columns is shifted to the left. If “MONTHLY”
is selected, the graph will display the rainfall history for the past 6 months.
The information displayed in column “0” is renewed on the first day of
every month, at midnight. The information contained in the columns is
shifted to the left.
