La Crosse Technology WS-7038U instruction manual II Numerical Representation of the BAR Graph

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.
