In your previous emails you mentioned that early units may need to be re-calibrated and that the app would take care of that. Now that the app has launched how do I make sure that my Anova Precision Cooker is calibrated correctly? ---

@nicknicknick Once you’ve paired your unit, go to the settings and you’ll see the option to calibrate. This is where you can re-calibrate if you believe your system is off a few degrees. There are some users who have tested their device against other thermometers and believe their Precision Cooker is off, which is why they re-calibrate. Chances are, yours is okay but we’ll have more info on our Help Desk for this next week. ---

I found that, but the only thermometer I have in my house is a meat thermometer, which I’m guessing wouldn’t give me the most accurate reading in water. I did try it though and it showed that my Anova was 1.5 degrees off, but again, using a meat thermometer to calibrate it probably isn’t the best idea, so if it really is off I’m worried that it will be even more off (or just still off) if I try to recalibrate it. ---

@nicknicknick Agreed, your meat thermometer isn’t the best frame of reference but it’s decent to compare against if you think your unit is 5+ off, which we have seen in some cases with earlier devices. Since the meat thermometer is only reading a temp. discrepancy of 1.5 degrees, I’d say your Precision Cooker is the more accurate of the two and not in need of re-calibration. Hope this helps and if you do choose to re-calibrate, let me know! I’d love to hear about your experience doing so to get an understanding of the ease of the feature’s use. Thank you! ---

Has anybody ever tried to calibrate their units against an ice bath, a la the calibration instructions for the thermapen? ---

@jshannon I’ve tried to do it with slush ice - not very successfully. One thing is to use with a single point in thermopen, and another for pretty big device like Anova - you need to reach an equilibrium somehow. And there is a firmware bug in reporting low temperatures: [http://community.anovaculinary.com/discussion/comment/1586/](http://community.anovaculinary.com/discussion/comment/1586/) , though if you use any of the apps it wouldn’t matter (the apps report temperature correctly, unlike the Anova’s display).
