2 st60 wind displays show different info?

[Donheist]

Morning! I have 2 st60 wind instruments - crew can see one, helm the other. One appears to show correct info, the other radically different - speed and direction. They are daisy chained to single set of transducers.

Any ideas? Other than cover it up and rely on the good one?

Difference between true and apparent wind speed and angle ? The black dot showing which they are operating on is not easy to see !

Alas not - not just a bit different - it’s the other tack!

A bit above my paygrade now but would calibration work on just one instrument or both ? Are the wires in the correct slots and not crossed over ?

Have they always been like this or just recently started ? If just started, is one of the instruments now faulty.

Get manual and read up on calibration. They both act independently i.e. one is not a repeater, therefore both can be calibrated independently. There are two levels of calibration. See thread, link below, where this was discussed:-

Aha - that is interesting. Will calibrate. Thanks
