Wireless Wind Instrument Tuning

[Dan Smith]

I have the Racemaster (T075) with the T101 wind system and the T221 mast rotator on an F24 tri. The system gives consistent data about apparent wind and true wind direction but is no accurate tack-to-tack. I will get as much as a 5-degree difference in apparent wind and a 15-degree difference in true wind direction from port to starboard tack. Everything seems to be functioning and talking to each other but I think I need to tune the instruments so I get better tack-to-tack consistency.

How do I go about this tuning?
Thanks...Dan Smith
