Modes & Historical Data
Press the MODE button to view rainfall data for different modes. While a mode 
is being viewed, press the CLEAR button to erase the reading being viewed or 
press the HIST button to view historical readings. You will automatically exit 
HIST mode if no buttons are pressed for 30 seconds. Enter HIST mode at any 
time by pressing the HIST button.
EVENT Mode
When EVENT mode is selected, rainfall data is shown for the most recent 
rainfall. An event ends when no rainfall has been detected for 8 hours. An 
event may be a brief drizzle, or a multi-day storm. 
To display the last 7 rain event rainfall totals, press the HIST button. Each time 
the HIST button is pressed, one rain event is displayed with the event’s time 
and date. To clear an event from memory, press AND HOLD the CLEAR button 
while the event is being viewed. Clearing data from EVENT mode does not 
impact other modes.
1 DAY Mode
When 1 DAY mode is selected, rainfall data is shown for today.
To display the DAILY RAIN for the last 7 days, press the HIST button. Each time 
the HIST button is pressed, the total rainfall recorded for the day will be shown 
with the time rainfall started (if applicable) and date. To clear any DAY rainfall 
total from memory, press AND HOLD the CLEAR button while the data for the 
day is being viewed. Clearing a day’s rainfall data will subtract that rainfall 
amount from the WEEK, TOTAL A and TOTAL B modes.
WEEK Mode
When WEEK mode is selected, rainfall data is shown for the past calendar 
week (Sunday through Saturday).
To display the WEEKLY RAIN for the last 7 weeks, press the HIST button. Each 
time the HIST button is pressed, the total rainfall recorded for the week will 
be shown with the time rainfall started (if applicable) and date. To clear any 
WEEK rainfall total from memory, press AND HOLD the CLEAR button while 
the data for the week is being viewed. Clearing a week’s rainfall data will 
subtract that rainfall amount from TOTAL A and TOTAL B modes.
TOTAL A/B Mode
TOTAL A and TOTAL B are total rainfall measured since the rain gauge was 
powered on or since the last time the mode was cleared. To display the start 
time and date for TOTAL A or TOTAL B, press the HIST button. To clear  
TOTAL A or TOTAL B mode, press AND HOLD the CLEAR button while the 
mode is being viewed.
