Re: Garmin and Newton/Isaac different power readings

Thank you for the replies. The problem was the Garmin was lower (282w), not higher than the Newton (308w), so the Garmin does not appear to be dropping the zero readings. The Garmin also lost the satellite during the ride and didn't re-acquire so only recorded part of the ride - I am thinking it jus...

Garmin and Newton/Isaac different power readings

Something unusual today - I was doing a 30min TT for testing FTP and noticed that the power output being displayed on the Newton was different to what my Garmin Edge 500 right next to it was displaying (I use the GT firmware to send the Newton power to Garmin). Sure enough when I got home and upload...

Re: Calibration

OK, so I went and did 2 cal rides this morning - how do you judge which is the better file to use? The rides were over different courses but similar surface (good asphalt). As an aside, I had problems with not being able to get out of setup mode after performing the cal ride - the screen kept coming...

Re: Jet Black Z1 trainer Power Curve dismatches.

I have found the same problem with the iBike power curve for Jetblack Z1. Luckily, I have the Dynometer version which is the same as the Z1 but with an inbuilt powermeter, so I was able to compare that side-by-side with my Newton readings. I want to use the Newton because it can record the full sess...

Re: Calibration

Many thanks John, appreciate the quick reply. Three followup questions please - 1. where would I find the "calride" marker - do I need to view the file in text form? 2. will the "fine tune" procedure that I have done already stick, or should I do that again? 3. once I finish the ...

Calibration

I did my setup cal ride today with my new Newton. After the Newton indicated the calibration was finished (about 5km of riding) I just kept riding with the Newton still going for another 13km (wanted some data linked to my Garmin Edge using the GT firmware to make sure all working properly). When I ...
