Give yourself an elephant stamp for an excellent answer!
The temperature measured means nothing except it was a temperature measured.
It won't translate to another person's setup or even the same type of roaster. There are so many variables that can change the expected number.
DON'T GET HUNG-UP ON SOMEONE ELSE'S NUMBERS
Okay, now that's out of the way...
Perfect. Shows consistency in what you are doing, it really doesn't matter if you see 45C, 145C or 245C... the number you see makes sense for your roaster and conditions and if you can repeat it (as you can) then you are well on the way to being able to make fine adjustments and taste the differences.
I'll let you into a secret, Arabica beans have a built-in thermostat that cracks at 196C.
Yep, that's right, when you hear first crack the bean temperature is 196C so you can adjust to "real" numbers using the bean as a guide.
Luckily we have that covered in Roast Monitor too. If you make the following changes to your preferences.txt file you will calibrate your temperatures with the actual temperature of the bean (regardless of where you have the probe).
Change this:
Code:
# Meter calibration factors.
meterAdjustMults=1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0
meterAdjustAdds=0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0
To this:
Code:
# Meter calibration factors.
meterAdjustMults=1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0
meterAdjustAdds=51.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0
or better still to this:
Code:
# Meter calibration factors.
meterAdjustMults=1.3 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0
meterAdjustAdds=0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0
The first one will add 51C to the read temperature, it will make low temperature readings wrong but it will be calibrated accurate at first crack.
The last one will make all readings on the primary HeatSnob 30% higher and will be at its most accurate at first crack too.
Make sense?
You can find the setting file at:
My Documents\CoffeeSnobs\Preferences.txt
Just open it with Notepad, make the edit and save it.
Re: Artmans questions... please post the specific Roast Monitor questions in the Roast Monitor thread, I would rather reply to them there so others benefit from the answers instead of them getting buried here.
