How to install a LabJack (U3)?

Build 20 up and running. But it is nightime here now and there’s still some hours of darkness. I’ll tell you tomorrow (late today for you).

Good morning Brian…

We’ll have a bright sunny day today. Build 20 is still doing exactly the same. No changes.

ok, lets start looking at logging the data to see what is happening:
use this update:
http://www.weather-display.com/downloadfiles/WeatherD.zip
and then let me know what appears under view, ws2010/ws2500 data setup

Not sure if I have to change any data there…


Hi
no, do not click on any settings there

so, nothing is being logged about labjack solar?
thats is a clue then

do you have labjack solar ticked in the labjack setup and you have the switch on the solar setup?

Sorry Brian, maybe I did something wrong. I restarted and this is what I get. The volts reading is Ok.


next to try:

Next for you…

Today there’s no log like yesterday, all I have is this you can see below. Anyway, there have been changes: values went higher at sometimes, but they are not still the desired ones:

Something I’ve seen today: solar percent readings at main screen and at solar sensor setup does not match. The good one is that of the main screen:

what I did was *10 the raw value
(and i removed the logs)
so, now, try reducing the max value in the solar setup?

re the 2 values, the one in the solar setup only gets updated when its opened

Ok, I’ll try tomorrow again.

Today I had it set to a max 3.5 mv. Days ago it was 100 times lower the max mv to get 10 times lower the solar. So with your *10 raw value it makes sense to be 100 times lower the max mv to get the “almost” correct solar.

Why almost? Because of that difference between main screen and solar setup readings. I’ve been checking it using clientraw offset #34 reading, the same as solar setup one. All day these values have been slightly higher than expected. Tomorrow I will check it using the main screen value, I think that is the correct one.

Hi Brian…

I made today a new test. Although it has been a rainy day, I’ve been able to get some interesting data. Labjack interface works fine, no problem at all. Solar readings at the main screen are correct, differences with the real theoretical ones are insignificant (Diff WD % column below). But readings at solar setup and clientraw are significantly higher than it should be, about 10%-13%:

Hi Brian…

Did you see something about this matter? I think is teh same as in http://discourse.weather-watch.com/t/25043

Thanks.
