Cumulus Basic Installation Guide - pdf

Cumulus Basic Installation Guide - I don't know who put this together but I think it would be a good idea to add a note in the FO section to explain amending pressure to relative. This comes up quite often and would avoid repeating the instruction. I am happy to amend it but I don't have a PDF editor.

Is the author out there?

Perhaps it should go into FAQ's? What is best?

think it is in the FAQ's isnt it?

Cumulus doesn’t show the same pressure as my Fine Offset console

First of all, check that you are comparing the Cumulus display with the ‘relative’ pressure on your console. Cumulus displays pressure corrected to sea level, which the console calls ‘relative pressure’.

If your relative pressure still disagrees with the Cumulus display, it may be due to the following: The Fine Offset stations only supply absolute/station pressure to Cumulus, so it has to adjust to sea level. When Cumulus starts, it reads the pressure ‘offset’ (the difference between absolute/station and relative/sea level pressure) from the station so it can use it subsequently to calculate the sea level pressure. Sometimes the offset that is read is clearly garbage, so Cumulus uses zero as a best effort.

To circumvent this, you can edit cumulus.ini, and in the [Station] section add an entry:

Code: Select all

EWpressureoffset=x.y

Hi Rob,

Yes I did read the FAQ's but it's better to amend it in the logger, that way the logger also will have the correct pressure don't you think.... well that's how I setup mine

edit.

I missed out the important point that a new person may not know anything about relative pressure and how to set this in the console, the FAQ doesn't cover it at all.

Ahh right, yeah with ya Neil, sorry mate,

The FAQ entry isn't quite the same thing, because in the case where you hadn't set your relative pressure Cumulus would display the same pressure as the console.

I suppose the question here is: should we be providing an alternative to the weather station instruction manuals, and if people haven't bothered to read their station manual, will they bother to read the Cumulus installation guide?

But as it's a frequently asked question, then maybe it should be a FAQ.

So true ...... Horses and water

At least we can just point them to the FAQ. I've never made an entry in the Wiki but I'll try and put together something and then ask for help if I get stuck.

I know I shouldn't be so cynical, but it gets frustrating when people have gone to the trouble of producing all this documentation... I try to tell myself that for every person who clearly hasn't read the documentation, there are a hundred who have

You can use the snazzy new editor, it'll be a breeze.

In my case a phrase comes to mind "hung by his own petard"
