Tacx vortex calibration

I calibrate my trainer before every workout. Tacx vortex smart. Sometimes offset is zero or really close. Other times it’s 65000ish. Is that normal?

Bump. This happens to me also. I Calibrate in the Tacx app first and then close it out. Then in TR and workout. Tire pressure is always 120psi as recommended by Tacx. Don’t know why it happens.

I used to get this before i started using powermatch with a power meter. if you take a little bit of pressure out of the tyre then you should get a more normal reading. the 65000 is definitely an error
