AeroPod, PowerPod and Newton

I have done a Wind Cal inside before I ride. Before the Wind Cal, it shows readings of, say 2.4 or -1.6 for example. I press the centre button and the numbers settle at zero and the Wind Cal is "Done". After the ride, Isaac shows I had a tail wind the entire ride (would be nice wouldn't it?). I have to use the Analyze Wind in Isaac, set the Ave. Ground Wind to zero then the wind looks about right, a little head wind out and little tail wind back.

Am I doing something wrong when I set the Wind cal on the Newton?

Please post your ride file

Original file with appended file (data reset)

It's important to do the Wind Cal correctly. Assuming you've done this, then your profile is incorrect.

I looked at your profile and the wind scaling factor was 0.57, pretty low. This would cause constant tail winds.

I did a Check Calibration step and got the modified profile, attached. Your WSF is now 0.97, quite reasonable.

Load this profile into your Newton and give it a try.

Thanks John. I will upload that profile.

I do the Wind Cal indoors (no wind) or if outdoors, I cup my hand over the port.Is this correct? Reading more posts, I gather that I really shouldn't need to do a wind cal after a succesful cal ride. Correct?

Thanks again.

How do I upload the .ibp file. Isaac won't open it.

I figured it out.I'll give it a whirl today.

Hi John;

I've atttached a ride file with the profile you provided. No post-ride adjustments applied.

If you perform an "Analyze/Check Calibration" on your ride file, you'll see that there is essentially zero correction. So, all is well!

Thanks for the help.

I have to say, being able to do the analyze.check calibration of a ride is a real benefit!
