

Heelandtrimcanbecalibratedusinganoffsetaswell.Theoffsetin

Ifnooffsetshavebeenprogrammed(0degreesforbothheelandtrim),

theappwillpromptyoutocalibratethesensor.Thiscanbedoneinone

oftwoways.”

Toautomaticallycalibrateheelandtrim,makesuretheboatisrelatively

stationary.Pressandholdthecirclemarked“HoldtoCalibrate.”Theapp

willbegintocalculateanaveragepitchandrollreadingover10seconds

andanorangebarwilldisplaytheprogress.Oncethebarflashesgreen,

theaveragereadingforbothheelandtrimwillautomaticallypopulate

theoffsetfieldsandthesensorshouldreadapproximately0degrees

under“Value”forbothheelandtrim.Remember,thecalculationusesan

average,soanymovementoverthemeasurementperiodwillimpactthe

Calibratingspeedbytravelingaknowndistanceisacommonmethodof

calibration,butthestartandendpointsaretypicallyfixedtotheground

andasinglerundoesnottakeintoaccountthemovementofthewater

ThereareseveralmethodsofspeedcalibrationusingtheCASTapp.





BASICSPEEDCORRECTION

Thesimplestwaytocalibratespeedisasinglepointpercentageoffset.

Thistypeofcalibrationappliesafixedpercentagecorrectiontoevery

readingfromthepaddlewheel.

NavigatetotheSpeedCalibrationtab.Bydefault,thespeedcalibrationis

setto“OFF.”

Enablethe“BASIC”speedcalibration.

Ifthedesiredpercentageadjustmentisknown,youcansimplyenterit

intotheCompensationfield.

Ifyouwouldliketheapptocalculatethecorrectpercentageadjustment

foryou,tapthewizardicon.



CASTappcancalculatethepercentageusingoneoftwomethods.

 SOG:SpeedthroughwateriscalculatedusingaGPSreference

speedoverground.

 Distance:Speedthroughwateriscalculatedusingtraveltime

overaknowndistancesuchasameasuredmile.



SOGMETHOD

TheSOGmethodallowstheapptocalculateyouraveragespeedover

groundusingtheinternalGPSinyoursmartdevice.Youcanalso

manuallyenteranaveragevaluefromanexternalsource.

Bringtheboatuptocalibrationspeed.Thisisthespeedwhereyouwant

thegreatestaccuracyinyourspeedreadingandwillbedifferentforeach

boat.

Oncetravelingatarelativelyconstantspeedanddirection,tapthe

“Primary”button.Theappwillcountdownasitcalculatesanaverage

indicatedspeedfromthepaddlewheelandanaverageGPSSOG.



13



Oncecomplete,theaverageforeachvaluewillbeshownandthe

“Primary”buttonwillchangeto“Reverse.”

Turntheboat180degreesandbringitbacktoapproximatelythesame

speedusedintheprimarydirection.Youdon’tneedtoholdexactlythe

samespeedfromtheprimaryrun,butthecloser,thebetter.Maintaina

consistentspeedanddirection.

Tap“Reverse”andwaitfortheapptocountdownwhiletheaverage

speedsarecalculated.Thesecondrunintheoppositedirectionallows

theapptocalculatethespeedofthecurrentinthewaterandremoveit

fromthecalibration.

Oncecomplete,theappwilldisplaythecalculatedpercentage

adjustment.Tap“Apply”tosavethevalue.

Thespeedcorrectionvaluehasnowbeencalculatedandsavedto

networkandtransmittedwirelesslytotheapp.Alldevicesconnectedto

theNMEA2000networkwilldisplaytheadjustedvalue.

ThevaluecanbemanuallyadjustedbytappingthevalueontheSpeed

Calibrationscreen.



DISTANCEMETHOD

ThedistancemethodofspeedcalibrationwillnotmakeuseofGPS.

Instead,you’lltravelaknowndistanceatarelativelyconstantspeed.The

appwillcalculatetheaveragespeedtraveledusingthetimerequiredto

covertheknowndistance.Itwillalsocalculatetheaverageindicated

speedfromthepaddlewheelandcomparethetwo.

Note:Calibrationusingaknowndistancerequiresbothanaccurate

measurementbetweentworeferencepointsandanaccuratetimeto

travelbetweenthem.Theshorterthedistancebetweenpoints,themore

potentialthereisforerrorinthemeasurement.Aminimumdistanceof

onestatutemileisrecommendedforadistance‐basedspeedcalibration.

Selectthe“Distance”button.

Entertheknowndistancebetweentwopointsintheunitsindicated.

Bringtheboatuptocalibrationspeed.Thisisthespeedwhereyouwant

thegreatestaccuracyinyourspeedreadingandwillbedifferentforeach

boat.





Whenyoupassthestartpoint,tap“Start.”Theappwillbegincountingin

Whenyoupasstheendpoint,tap“Stop.”Thenumberofrunswill

increasebyoneandthecalculatedspeedswillbeshown.

Thenumberofrunsalreadycompletedwillbeshownas“Completed

Runs.”“TotalTime”isacountofthetotalnumberofsecondsforallruns.

“RunSpeed”showstheaveragerecordedpaddlewheelspeedonthelast

correctionfactorcalculatedonthepreviousrun,and“Correction”isthe

overallaveragecorrectionfactorcalculated.

Followthesameprocessforadditionalruns.Ifyouwouldliketothrowa

runout,tap“DiscardRun”oncecompleteandtryagain.

Note:Ifyou’reperformingthecalibrationinalocationwhereasignificant

Note:MakesuretheattitudePGNisenabledontheNMEA2000page.

Onceenabled,makesurethesensorhasbeencalibratedwiththeboat

stationary.RefertotheOffsetsPagesectionformoreinformationabout

calibrationoftheattitudesensor.Heel‐correctedSpeedCalibrationand

theAdvancedCalibrationTablecannotbeusedwithoutattitudeenabled.

Changesinheelangleoftheboatwhileunderwaycanaffectthespeed

calculatedbythepaddlewheel.TheDST810canstorecalibrationsatup

totwodifferentanglesoneachsideinadditiontothestandard

calibration.Inordertoapplyaspeedcalibrationatmorethanoneangle,

theadvancedtablemustbeused.

Astheheelangleoftheboatchanges,thesensorwillshiftfromone

curvetothenext,interpolatingbetweenthem.

Forexample,ifa15%compensationisappliedat10degreesofheeland

a5%compensationisappliedat0degrees,thesensorwillapplya10%

compensationat5degreesofheel.

Heel‐correctedSpeedCalibrationsareappliedusingasimilarprocessas

theStandardCalibration.However,thenatureoftheprocessprevents

makingrunsinoppositedirections.Forthisreason,it’simportantto

performthecalibrationinslackwater.

BeginthecalibrationbyselectingthewizardiconontheHeel‐corrected

SpeedCalibrationwindow.LiketheStandardCalibration,theHeel‐

correctedSpeedCalibrationcanbeperformedusingtwomethods.

 SOG:SpeedthroughwateriscalculatedusingaGPSreference

speedoverground.

 Distance:Speedthroughwateriscalculatedusingtraveltime

overaknowndistancesuchasameasuredmile.



SOGMETHOD

TheSOGmethodallowstheAirmarCASTapptocalculateyouraverage

speedovergroundusingtheinternalGPSinyoursmartdeviceor

manuallyenteranaveragevaluefromanexternalsource.

Bringtheboatuptocalibrationspeed.Thisisthespeedwhereyouwant

thegreatestaccuracyinyourspeedreadingandwillbedifferentforeach

boat.

Choosetheangleatwhichyouwouldliketoperformthecalibration.

Makesureyoucanmaintaintheangleofheelenteredinbothdirections;

thesameangleisusedforbothportandstarboard.Theappwill

automaticallyrecognizeaportorstarboardtack;there’snoneedto

specifytherun,onlytomaintainasclosetotheselectedangleas

possible.

Oncetravelingatarelativelyconstantspeed,direction,andheelangle,

tapthe“Primary”button.Theappwillcountdownasitcalculatesan

averageindicatedspeedfromthepaddlewheelandanaverageGPSSOG.

Theappwillnotpromptforasecondrunasthisisoftennotpossible.It’s

processagaintoaddacalibrationfortheoppositeside,andkeepinmind

thetwowillfrequentlybedifferent.Tap“Apply”tosavethevalue.

Thespeedcorrectionvaluehasnowbeencalculatedandsavedto

DISTANCEMETHOD

ThedistancemethodofspeedcalibrationwillnotmakeuseofGPS.

Instead,you’lltravelaknowndistanceatarelativelyconstantspeed.The

appwillcalculatetheaveragespeedtraveledusingthetimetocoverthe

knowndistance.Itwillalsocalculatetheaverageindicatedspeedfrom

thepaddlewheelandcomparethetwo.

Note:Calibrationusingaknowndistancerequiresbothanaccurate

measurementbetweentworeferencepointsandanaccuratetimeto

travelbetweenthem.Theshorterthedistancebetweenpoints,themore

potentialthereisforerrorinthemeasurement.Aminimumdistanceof

onestatutemileisrecommendedforadistance‐basedspeedcalibration.

Selectthe“Distance”button.

Entertheangleatwhichyouwouldliketocalibrateandtheknown

distancebetweentwopointsintheunitsindicated.



Bringtheboatuptocalibrationspeedandtheselectedheelangle.Thisis

thespeedwhereyouwantthegreatestaccuracyinyourspeedreading

andwillbedifferentforeachboat.

Whenyoupassthestartpoint,tap“Start.”Theappwillbegincountingin

seconds.

Thenumberofrunsalreadycompletedwillbeshownas“Completed

Runs.”“TotalTime”isacountofthetotalnumberofsecondsforallruns.

“RunSpeed”showstheaveragerecordedpaddlewheelspeedonthelast

run,while“Speed”showstheoverallaverage.“RunCorrection”isthe

correctionfactorcalculatedonthepreviousrun,and“Correction”isthe

overallaveragecorrectionfactorcalculated.

Followthesameprocessforadditionalruns.Ifyouwouldliketothrowa

runout,tap“DiscardRun”oncecompleteandtryagain.

Note:Ifyou’reperformingthecalibrationinalocationwhereasignificant

currentmaybepresent,makesuretoperformanevennumberofruns

withhalfinonedirectionandhalfreturningintheoppositedirection,as

closeto180degreesaspossible.Thiswillensurethecalculatedaverage

accuratelyaccountsforthecurrent.

Oncecomplete,tap“Apply”tosavethevalue.Theappautomatically

detectsthedirectionofheelandpopulatesthecorrectfield.

Thespeedcorrectionvaluehasnowbeencalculatedandsavedto

ADVANCEDSPEEDCALIBRATIONTABLE

Note:Theadvancedspeedcalibrationtablewilloverrideanyother

programmedspeedcorrections.Itwillnotbeaddedontopoftheexisting

speedcalibration.Beforeswitchingtotheadvancedcalibrationtable,

makesuretocarefullyquantifytheperformanceofthesensorwithout

anycorrectionsinplace.

TheAdvancedSpeedCalibrationTableallowsfineadjustmentofspeed

Uptotwoanglespersidecanbeselected.

Upto10non‐zerospeedscanbeaddedtothetable.

Note:Whenusingtheadvancedcalibrationtable,makesurethehighest

speedinthetableisthefastestspeedthevesselwilltypicallyachieve.If

thespeedexceedsthelargestvalueinthetable,thesensorwillapplya

linearcorrectionofthesameslope.Thiscanloseaccuracyquicklyifthe

lastspeedisverylow.It’simportantthetableincludetheentirerangeof

Tousetheadvancedspeedcalibrationtable,first

switchspeedcalibrationto“Off.”

Eithermanuallyorusing3

partysoftware,collect

thedifferencebetweenindicatedspeedandactual
