Model 02032M has a Previous Events window .... the top value is the cumulative rainfall and it appears to be working correctly. The bottom value is a date and it has displayed 1 / 1 / 15 since the unit was started ... what is this date? Does it change on its own or do I need to update it?
The bottom of the rainfall box will show you previous events. The all time total will start from the day the unit first measured rain. If the display measured rain on 1/1/15 is the default day the display starts with when initially booting it up. If the tipping cups in the sensor tipped before the date was set on the display, you will have a reading from this date. To correct this issue, you can factory reset the display unit. To do so, press and hold the reset button for 10-12 seconds or until the display clears completely. NOTE** this will clear all historical data. Please let us know if you have any other questions. Thank you.
