I have a model 01536/8900123 weather station that will not record rainfall anymore. I replaced the batteries and checked for any blockages. weverthing else works fine.

Remove the batteries from both units for a couple of hours. Replace the indoor unit battery and then the outdoor battery. This will effect a reset of sorts. Don't forget your rainfall can be different to someone 600 meters away. Having said that 100mm / 4 3/4" difference is a lot.

The National Weather Service Website should be able to help you. If you go to their website (www.weather.gov) and type in the zip code for a location in the upper left it will take you to the forecast page for that location. If you scroll to the bottom of that page and click on past weather information you can view the rainfall totals since January 1. Not sure if that is exactly what you need.

To see current rainfall totals on more of an hourly basis and not once a day when the above site updates check out http://aviationweather.gov/adds/metars/Type in the METAR code for that station (if you don't know it it is in the station.txt file, link on the page). Type that in the box and then make sure you click the button for translated. That will tell you the hourly report for that weather station which, if there was rainfall, should say how much fell.

We are having the same problem

what is the model?

What model number

Remove the cover and check is a spider has built a web over the
tilt bucket. I have to clear mine ona regular basis.
If this is a proglem, spray the inside if the cover with a surfase spray.

To set station Hold SET key down for 3 secs. Press SET key to select setting in this sequence. 1. Time Zone 2. 12/24hr format 3.Manual time setting HR/Min. 4. Calendar setting y/mm/dd 5.Temp display C or F 6.Air pressure display hPa or inHg 7.Relative pressure setting from 919.0hPa-1080.0hPa 8 Pressure threshold (sensitivity)Default 2 9.Storm threshold Default 4 10.Wind speed reading km/h, mph etc 11 Rainfall display in mm or inch. Use the + and History keys to adjust values (History key is - ) When replacing batteries Fit outside unit ones first then fit inside unit ones in that sequence so it can interpret the security code.

My Oregon Scientific Weather Station RGR122: The total rainfall and rainfall windows won't stop flashing. I have removed the new batteries several times, changed batteries in outside collector, and reset the inside unit multiple times. What can I do to solve this problem. Frustrated! Darla
