VI. RESETTING RAINFALL INFORMATION
A. RAINFALL QUANTITY TOTALS
Resetting the Rainfall Quantity Totals will clear the numeric data held
under “TOTAL,” “1h,” and “24h,” resetting all to 0.00 (appearing in
LCD 5).
From any selected normal display mode:
1. Press and hold the RAIN button for 3 seconds.
2. Resetting will automatically shift to display “TOTAL.” The
numeric data under “TOTAL” in LCD 5 will read 0.00.
Note: Resetting the Rainfall Quantity Totals does not affect the Rainfall
History represented in the bar graph.
B. MANUAL SETTING OF THE RAIN MULTIPLICATOR
Note: The rain multiplicator is the height of rain held in the
teeter-totter bucket (inside the rain gauge) before it is tipped. It is
preset to a value of 0.267mm by the manufacturer prior to shipping;
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 also reset the
Rainfall Quantity Totals).
2. Checking the polarity, install batteries.
3. During the brief 2 seconds that all LCD screens light up,
simultaneously press and hold the MOON and MIN/MAX buttons.
4. Three numbers will appear in LCD1 (“267” is the default), with the
last digit (7) flashing.
5. Use the CH/+ button to change the last digit to a 7 and press the
SET button.
6. Use the CH/+ button to change the middle digit to a 6 and press
the SET button.
7. Use the CH/+ button to change the first digit to a 2 and press the
SET button. The Weather Center will enter into normal operating
mode. Do not press any buttons while the Weather Center searches
for transmisssion signals.
8. Follow Program Mode for set-up proceedures.
