Rainfall History
Your Wireless Rain Gauge will store the rainfall history for:
• Last hour
• Last 24 hours
• Daily rainfall (current day plus up to last six days)
• Weekly rainfall (current week plus up to last six weeks)
• Monthly rainfall (current month plus up to last six months)
Note: The recording period starts when the batteries are installed. Upon setup, the base unit will automatically display
the Daily Rainfall history.
Press “HISTORY” to toggle through these readings:
• Weekly rainfall
• Monthly rainfall
• Last hour rainfall
• Last 24 hour rainfall
• Return to Daily rainfall
The Rainfall History Bar graph displays in increments from 0.1” to 6.0” (10 mm to 60 mm). Most often the actual rainfall reading will fall between increments. The bar chart will show the last increment that was reached.
For example: if the actual rainfall is 0.8” (20 mm), the bar graph will not show 1.0” until the actual rainfall total reaches 1.0” (25 mm).
