Reading the Artisan gas and fan settings

[thusband]

How are the Artisan gas and fan graphs read?

Here's part of SusanJoM's Artisan graph of a roast where Airflow stayed at 50% throughout the roast and gas was steady at 3.5 and then down in increments starting at about 300F.

I'm struggling to see where it says, on the graph, 50% air and 3.5 kPa gas.  The data points don't seem to correspond to the numbers on the right or left.  Or do they?  I get the general idea of what the roast was like but I wouldn't know what the settings were without her comments.

If I'm profiling my roasts and want to reproduce a roast how do I know what I did 6 months from now?

[SusanJoM]

The reason I added the comments is because you can't see what the settings are on my buttons.  I, however, can, and you of course will be able to reference your own.  Here are the button settings that created that profile.

OK thanks SusanJoM.  So there's no direct correlation with the graph and numbers on the right or left?  It just gives you a close approximation of the settings?

I'm going to add some more buttons.

You can get these values either by Susans reciepe for buttons, or the (in later versions of Artisan, already set) sliders on the left side. (These are described in the Hottop (or was it Behmor) setup guide.)
Anyhow, if you look at the bottom part of the graph, there are "stripes" every 10F from 100F to 200F. I use Celcius settings for my Artisan setup and then the numbers on the right goes from 0 to 10, where Fahrenheit goes from 0-20 to denominate 0-100%. The scale on the right is primarily for the RoR/Delta values.

[SusanJoM]

That area from 0 - 200 (on the left;  0-20 on the right) equals 100%.  When you set your buttons, you set them to percentages. 

Since 3.75 is the highest that my gas gauge goes, for example, 3.75 would be 100%;  3.5kPa is 93% (3.5/3.75); 3 kPa is 80% etc....
The Grate is either open or closed, so it is either 100% or 0%.
I only use one fan setting and it is 50%, but I have hidden spaces for adding more buttons if I decide to use the fan differently at some point.

I think you've already read the downloadable document Setting Up Events in Artisan?  Check that for the details of how to set up the buttons.

Right.  I get it!  Thanks SusanJoM and edtbjon.  Sorry for my slow uptake.

This is an area where hand charting seems more accurate and easier to see and replicate. Of course I'm new to Artisan, but the events table does not have enough tabs at least for me. I can flip open a hand written graph and easily repeat the profile seeing all the settings/temps on a single horizontal line.

[thusband]

Would you have a sample of your chart, hankua?  Is it pre-printed and you fill in the blanks?  Jotting down the gas and fan might make sense.

[hankua]

Sure!
GregR has my graphs posted in the download section; feel free to copy/modify. There are versions in *F and *C.

I totally agree with Hank.  I only started pushing the buttons after using Artisan for about 6 months and making notes by hand on a pre-printed form.   Now I mainly use them if I want to demonstrate how a particular profile is produced with my less popular perforated/slow configuration.
