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.

II) NUMERICAL REPRESENTATION OF THE BAR GRAPH

The bar graph displays the columns sequentially from “0” to “6” until all columns

are showing. Then they are hidden again, and the sequential display is repeated. It is

possible to read each column one at a time, simultaneously displaying the numeric

measurement for that column above the bar graph. For example, the weekly rainfall

total from 3 weeks ago may be viewed. Also, the numeric data from each column

will correspond to the preveouly selected history (“DAILY,” “WEEKLY,” or

“MONTHLY”). To view individual totals from the last six periods:

1. Hold down the HISTORY/+ button for 2 seconds. The numeric data from

column “0” should appear at the top of the LCD screen, with the

“RAINFALL” icon displayed above the data.

2. Press the HISTORY/+ button again, column “1” will be highlighted, and the

numeric data will be displayed above the bar graph.

3. Continue to press the HISTORY/+ button until the data from each column (0

through 6) has been displayed.

4. Pressing the HISTORY/+ button once more, after viewing the data from

column 6, will exit this mode—returning to normal operation.

III) MANUAL RESET OF THE RAIN MULTIPLICATOR

Note: The rain multiplicator is the amount of rain needed to tip the teeter-totter

bucket (inside the rain gauge). The multiplicator is preset to a value of “105”

(0.0105 inches per tip); this number produces the most accurate rainfall

measurement. There is no need to manually set this number unless it has been

changed.

1. Remove the batteries and wait 30 seconds. This will reset the 1-hour

rainfall total, but the bar graph and other totals will remain.

2. Checking the polarity, install batteries.

3. During the brief 2 seconds that the LCD screen lights up, hold down the

HISTORY/+ button, until “105” appears in the LCD (the “5” will be

flashing).

4. If the multiplicator is not 105; use the HISTORY/+ button to to change the

last digit to a 5. Press the RAIN/SET button to confirm and shift to the

middle digit.

5. Press the HISTORY/+ button to change the middle digit, and press the

RAIN/SET button to confirm and shift to the first digit. Repeat process for

the first digit.

6. Press the RAIN/SET button to exit the Rain Multiplicator mode, and to enter

the normal mode. Follow Program Mode for set-up proceedures.

IV) COMPLETE RESETTING OF PRECIPITATION DATA

Note: The rain data held by the bar chart and other rain totals (excluding the

1-hour total) will be stored and displayed again, even after the batteries have been

removed. Therefore it is necessary to apply the following instructions to reset the

bar chart and other totals, if desired.

1) Enter the Rain Multiplicator mode as instructed in steps 1 through 3 of the

Manual Reset of the Rain Multiplicator section above.

2) After setting the rain multiplicator, while the left digit is flashing, press the

RAIN/SET button for 8 seconds. This will clear data, and reset it to 0.

V) RECEPTION REQUIRMENTS

The Rain Monitor receives data from the Rainfall Transmitter every 5 minutes, while

the Rainfall Transmitter transmits data every 1 minute. Data is transmitted

immediately after rain has been detected. If 3 transmission attempts are made and no

data is received, “---” will be displayed in the LCD. If this is the case, reset the Rain

Monitor.

A) RESETTING

1) Remove batteries from the Rain Monitor and Rain Gauge.

2) Wait 30 seconds, or start-up and transmission problems may arise, then

reinstall the batteries.

3) Follow Programming instruction.

The Rain Monitor cannot receive data in the Programming Mode, nor during the

numeric display of the bar chart. Reception is also interupted when a button is

pressed, and will continue when the button is released.

The transmission range is approximately 80 feet (25m) in open space. The

surrounding environment and interference levels influence this transmission range.

VI) ICONS

A) FLASHING RAIN CLOUD

A flashing rain cloud appears in the upper right hand corner of the LCD screen,

when the Rainfall Transmitter is accumulating rain and transmitting data.

B) SATELLITE ICON

The satellite icon appears above the right column of the bar graph, when the

Rain Monitor is searching for a signal from the Rainfall Transmitter.

MOUNTING

Note: Before permanently mounting, ensure that the Rain Monitor is able to receive

signals from the Rainfall Transmitter at their desired location. Obstacles such as walls,

concrete, and large metal objects can reduce the range. Place units in their desired

location, and wait approximately 15 minutes before permanently mounting to ensure that

there is proper reception

I) THE TX5U—RAINFALL TRANSMITTER

The Rainfall Transmitter can be mounted in two ways:

• simply placing it in a desired location, or

• mounting it to a surface with the provided screws.

Ensure that the Rainfall Transmitter is completely horizontal and stable.

1) Rotate the rainfall collector

separating it from the base.

2) There are two cylindrical

holes in the base to guide

the mounting screws. Place

the base over a desired

mounting surface. With a

pencil, mark the mounting

surface through the

cylindrical holes.

3) Where marked, start the screws.

4) Place the base over mounting surface. Install screws through the cylindrical

holes and into the started holes on the mounting surface.

5) Secure the screws, ensuring that no part of the base can lift off the mounting

surface.

6) Remove the manufacture tape from the teeter-totter on the base. If this is

not done there will be no way to measure rainfall, and no measurement will

display on the Weather Center.

7) Place the rainfall collector onto the base. Place the 3 tabs (on the rainfall

collector) into the tab slots (on the base) and turn counter-clockwise.
