Changing Power Tap Batteries

Woody Freese

Quick question - When batteries are changed in the compoter head and the hub, as well as the HR monitor strap, does the computer need to be recalibrated?

Thanks -

Woody, I have not seen that changing batteries in any of the devices requires a recalibration of the hub. With that said, I almost always do a manual zero process on the hub at the start of any significant ride. I always manual zero before an FTP test.

+1 on what Matt said. I use a few different Garmin heads with my Powertap G3 and I always use the Ant+ Power Meter Calibration before every ride. It take 5 seconds (mainly bottom pushing) and I do it right before I throw my leg over the saddle....
