ROR, filters, sampling, over sampling, etc
by Fred B
I've been using the Artisan program for some time now on an Ambex ym2 with
an Omega data logger and a 2 ghz dual core laptop. I just loaded 0.8 and
I'm hoping that I might get smoother ROR values with this version as I see
that is one of the improvements. Maybe the issue is the fast response of my
probes? Is there a way to compensate for this in Artisan? Can you make
some recommendations as to the EXTRA settings for the newer version and
maybe something up to date about the effects of using values too large or
too small? My ROR just jumps around too much and by the time it's
dropping/rising too rapidly it's almost too late for me to do anything about
it. Could I benefit (or not and why) from using over sampling or a higher
or lower sample rate? I'm at 4.0 now. Which curve smoothing values affect
real time displays and which don't? I've been reading Scott Rao's new book
and find myself evaluating my roasts and looking carefully at ROR and 1st to
drop percentages so Artisan is so useful. Thanks so much to all that have
contributed to this great program.

Stacking Profiles
by justin
A function I’ve gone looking for is the ability to stack profile files over laying each other in Roaster Scope. This was for comparing the two or more roasts graphically on the same axis.

Re: [Artisan-user] Thermocouple Calibration
by Marko Luther
Hi George,
you can put a formula in the "Symb ET/BT" of the Device Assignment dialog (menu Config >> Device) for either ET or BT (a similar feature exists for the extra devices in the corresponding tab).
For example, putting the string "x + 10" (without the quotes) in the "ET Y(x)" field would add a constant offset of 10 to each ET reading. You can also put more complex formulas that in principle would allow for linear, quadratic and other approximations. See the Help button in that tab for further details.

Thermocouple Calibration
by George Stimak
Hi there,
I just wanted to check to see if there is an option in artisan to calibrate
(or set a difference to) the termocouple.
I had to place my secondary thermocouple about an inch from the
thermocouple that the roaster uses for temperature settings and over
limits. This slight difference is giving me about a 5-10 degree difference
in temps at high levels.
It would be nice just to go into artisan and tell it to read however many
degrees plus or minus to bring it in line with the other thermocouple.
The thermocouple itself is calibrated fine - tested it when we had all of
our other themocouples tested for the agency that handles air quality in
the area. It's just the difference in location of the bean mass that's
causing the slight discrepancy.
I'm wondering if I overlooked this setting, or if this may be a feature
request?
Thanks,
G
