Re: Rain rate discrepancy

Today the data log reported 1.7mm/hr (before MX started) and this was the only bucket tip for the day, and the chart agrees with that. However the dashboard, the rain rate gauge and theToday/Yesterday page all show a maximum rate of 3.6mm/hr, at the time of the single tip. This behaviour is consiste...

Re: Rain rate discrepancy

Computer motherboard meltdown caused a long delay in getting back up and running during the latest Covid lockdown, but MX is now running again on a new PC. I've now worked out what is happening, and the discrepancy in rainfall rate is because I applied a calibration multiplier of 0.46 to rainfall, a...

Rain rate discrepancy

I don't run my PC overnight so every morning I download the station data, first to Cumulus 1, then swap to MX for the rest of the day, They run in different folders so their data is saved separately. The main reason for this is to retain the capacity to access the Select-a-graph feature that C1 has ...

Re: Updated from Cumulus 1 and can't read dayfile.txt

Thanks again for your detailed advice, much appreciated. Starting a new day, MX commenced showing rainfall for the month and the year, but recorded a staggering amount for yesterday, a negative amount of over 9000mm! Unreal unrain! Swapping back to Cumulus 1 (running in a different folder) there was...

Re: Updated from Cumulus 1 and can't read dayfile.txt

Thank you sfws, I must have been having a senior moment and overlooked Windows was using / instead of - separators. After fixing that and correcting some date entries in the current month, MX opened without file errors and all charts are displaying as they should. That just leaves a problem of this ...

Re: Updated from Cumulus 1 and can't read dayfile.txt

Thanks guys for the help.... I corrected the earlier dates to the - separators using Notepad++, easy :D Then I checked the Windows date format in Control Panel/Region, noticed it was d/MM/yyyy so rightly or wrongly changed it to d/MM/yy which is how Cumulus 1 had been recording dates. Started MX aga...

Updated from Cumulus 1 and can't read dayfile.txt

After 10 years on Cumulus 1 I decided to try MX. Installed easily enough and I copied 10 years of data over into the new folders, as well as cumulus.ini. First problem: MX won't show rainfall for the current month or year and won't display temps in the chart for the past 31 days. The MXdiags.txt fil...

Re: Fine Offset 1080 suddenly more frequent lockups

Mine was sealed too. I prised the (glued?) casing apart however, and it could be joined again with more glue or just by using the weather shield. Because mine is in an enclosure (no shield) I just used a cable tie.

Re: Fine Offset 1080 suddenly more frequent lockups

I had similar problems on my 9 y.o.1090. Ended up removing the transmitter circuit board and cleaning it with a toothbrush and isopropyl alcohol to remove crud and oxidation, then applying clear nail varnish to the tracks as a protective barrier. Restored to health after that, but keep clear of the ...

Re: Fine Offset parts source?

I'd be interested to hear if bearings with rubber seals help reduce direction flutter without being too stiff. In my system (and my previous WH1091) the bearings in both wind instrument use bearings with shields (metal) which are low drag and ideal for the anemometer.

Re: Wind Speed Abnormality

I've had similar problems with the rain gauge not reporting, and came up with a simple test circuit involving a mini piezo siren, a 9v battery and an RJ11 socket, to plug the cable into instead of the transmitter. It's so easy to hear the pips (even from a distance) as the reed switch closes than st...

Re: Weather Station for Android

My extremes are set to 975 and 1040 and the forecasts are usually good. You could try lowering your low limit and see if that makes a difference.
