I’ve recently installed a new set of Nexus gear including an NX wind and sea data and an NX 2 multi. Gear’s all been calibrated by the rep. All’s good until I look at our true wind speed and wonder why we’re getting the sheet kicked outta us upwind when the true wind on the instruments is less than 10knts. I’ve compared the TWS on the instruments to that on the laptop. The two are quite different, with the amount looking to be the 1.7 factor for the double fin masthead unit and the 0.5m/s offset that the wand needs to get going. Both the instrument and the laptop show 1.7 calibration factor. The laptop shows the offset as 0.5m/s, but I can’t see where the same is set in the instrument. Anyone come across this or, better yet, got a solution?
