Newton Cal Ride: bad cal...bad cal...bad cal...

[healdsbiker]

I have not been able to achieve a good cal ride with my Newton - four attempts have resulted in four "bad cals". My setup is a Newton mounted on the handlebar with the dual-mount. I performed two "2 mile" cal rides on one day, on a mostly straight, flat road with low winds and no traffic. Both rides returned a "bad cal". I had performed a tilt cal earlier in the day, and did a wind cal between the two cal rides. I thought maybe I had missed something.

I used Isaac to go through the device setup again and told it to let me redo the cal ride from scratch. Today, I tried two more cal rides, both resulting in "bad cal". The first was 4 miles (2 miles out, 2 miles back), and the second was 2 miles. Wind was mild, traffic very low. I performed tilt and wind cals about 30 mins before the first attempt, and then again before starting the second attempt.

At this point, I don't know what to do to achieve a good cal. I did notice that the wind measurements were way off before and after the cal attempts. Maybe this is expected before a good cal ride is achieved.

I've attached the two ride files from today. Any help would be appreciated to achieve a good cal ride.

It looks like your wind sensor is not happy. Please contact Tom Gore at technical support@velocomp.com and he will help arrange to send you a replacement Newton.

I have a similar issue.
I've had issues with getting my Newton set-up, each ride seems to have a constant head or tail wind and the "check calibration" in Isaac varies with each ride.

Today I tried 4 cal rides (2 in the morning and 2 in the evening) and also received the "bad cal" message each time. I think the location was ideal (no-traffic) and there was very little wind.
I gave the unit at least 15 minutes as I rode to the location for the cal ride. I did a tilt cal, and a wind cal with a plastic bag loosely fitted over the unit.

I've attached 3 of the files:
