64 ST1000 Plus & ST2000 Plus Tiller Pilots - Owner’s Handbook6 Adjusting Tiller Pilot Settings6.2 Calibrating the tiller pilotCalibration Level 1: Rudder gainUse Calibration Level 1 to adjust the rudder gain. This must be setwhen your boat is under way, as described on page 58.Calibration Level 5: cruise speedUse Calibration Level 5 to set the boat’s normal cruising speed foroperation in Track mode.When interfacing with a navigation system, the tiller pilot uses theboat’s average cruising speed to perform track calculations.Note: If a SeaTalk speed instrument is connected, boat speed datawill be transmitted directly to the autopilot.Calibration Level 6: off course alarm angleUse Calibration Level 6 to set the off course alarm angle. This alarmwarns you if the autopilot is unable to maintain its set course.The off course alarm operates if the autopilot strays off course, bymore than the set value, for more than 20 seconds.You can set the limit in 1° increments between 15° and 40°.Locked headingBoat heading15˚ minimumD3264-2
Chapter 6: Adjusting Tiller Pilot Settings 65Calibration Level 9: magnetic variationUse Calibration Level 9 to input the level of magnetic variationpresent at the boat’s current position.• -ve variation = west• +ve variation = eastThe tiller pilot transmits this value onto the SeaTalk bus, so it can bepicked up by other SeaTalk instruments.Calibration Level 10: heading error correctionUse Calibration Level 10 to switch on Northerly or Southerly headingerror correction:• 0 = Off• 1 = Northern Hemisphere, 2 = Southern HemisphereYou might notice that the autopilot tends to be a little less stable onNortherly headings in the higher latitudes of the Northern hemisphere(or Southerly headings in the Southern hemisphere).This is caused by the increasing angle of dip of the earth’s magneticfield at higher latitudes, which has the effect of amplifying rudderresponse on Northerly (Southerly) headings. This error affects allmagnetic compasses and gets worse further away from the equator.With heading error correction switched on, the tiller pilot cancompensate for this error by automatically adjusting the autopilotgain (depending on heading). This will provide precise coursekeeping on all headings.6 Adjusting Tiller Pilot SettingsNorthNorthwithoutcompensationwithcompensationD3263-2
