SECTIONI:OPERATINGMODES



Pipeandcablelocatorsingeneralcanoperateinavarietyofmodesandfrequencies.Thefollowingis

abriefdescriptionofthebasicoperatingmodessupportedbytheXTpclineofpipeandcablelocators,

anditisnotintendedtobeacomprehensivelocatingtutorial.Foradditionalinformationonpipeand

cablelocatingtheoryandtechniques,refertoSchonstedt’strainingsectiononlineat

www.schonstedt.com.



Passive50/60Hz(P)



Inthepassivemode,thetransmitterisnotusedatall.Instead,thereceiversearchesforan

appropriateharmonicof60or50Hzsignals(factorypreset).Thesesignalsaretypicallypresentin

energizedpowercables,makingitpossibletolocatethemwithoutusingatransmittertoimposea

tracingsignalontothem.



PassiveCathodic(PC)



Longpipelinesusuallyhavetodealwiththeissueofcorrosion.Aknowngroupoftechniquesusedto

controlcorrosioninvolvestheuseofperiodiccathodesalongthepipelineandthecirculationoflow‐

levelcurrentsrectifiedfromthepowergrid.Thepassivecathodicmodedoesnotusethetransmitter

atall.Instead,thereceiversearchesforanappropriateharmonicofrectified60or50Hzfromthe

powergrid.Therefore,itispossibletotracepipelinesforlongdistanceswithoutusingatransmitterto

imposeatracingsignalontothem.



Conductive(C)



Intheconductivemode,thetransmitterimposesasignalofthe"active"frequencyontothepipeor

cabletobetraced.Itdoessobymakingdirectcontactwiththepipeorcableatapointwhereit

comesuptothesurface(atransformerbox,awaterhydrant,atelephoneswitchbox,agasmeter,

etc.).Thecircuitisclosed,providingareturnpathbyagroundstakethatisburiedinthegroundinthe

vicinityofthetransmitter.



InductiveClamp(IC)



Intheinductiveclampmode,thetransmitterimposesasignalofthe"active"frequencyontothepipe

orcabletobetraced.Itdoessobyenergizinga"clamp"thatisplacedcompletelyencirclingthepipe

orcableatapointwhereitcomesuptothesurface(atransformerbox,atelephoneswitchbox,agas

meter,etc.).Theclamptheninducesacurrentontothepipeorcable.Inthismode,itisnot

necessarytoprovideareturnpathfortheinducedcurrenttothetransmitter.Theinducedcurrent

willtravelonthepipeorcableforadistancemakingitpossibletotraceit.



Inductive(I)



Intheinductivemode,thetransmitterimposesasignalofthe"active"frequencyontothepipeor

cabletobetraced.Itdoessobyradiatingasignalthroughtheinductiveantenna,whichisplacedon

thegroundinadirectionperpendiculartothepipeorcablebeingtraced.Theinductiveantennathen

inducesacurrentontothepipeorcable.Inthismode,itisnotnecessarytoprovideareturnpathfor

theinducedcurrenttothetransmitter.Theinducedcurrentwilltravelonthepipeorcablefora

distancemakingitpossibletotraceit.



Sonde(S)



Inthesondemode,thetransmitterisnotusedatall.Thismodeisusedtotracenon‐metallicpipesor

metallicpipeswheretheothermodesareinapplicableorinefficient.Asmallsonde,or"beacon

transmitter",ispushedthroughthepipe,andthereceiversearchesforthesignalemittedbythe

sonde.Sincethesignalbeingtracedbythereceiverisproducedbythesondeandnottravellingalong

thepipes,therearesomedifferencesinthewaythereceiverisused.Duetothenatureandstrength

ofthesondesignal,itisnecessarytohavesomeideaofwherethesondeis(inordertonarrowthe

searchareatoaradiusofseveralfeetcenteredaroundthesonde).Thisisusuallynotmuchofa

problem,sincethesondeis"guided"byadeviceundercontroloftheworkcrew,oftenwithacamera

attachedtoit.

SECTIONII:THEXTPCPRODUCTLINE



Whileemphasizingportability,size,andconvenience,theXTpclineofpipeandcablelocatorsoffers

severalchoicestosuitalmostanytypeoflocatingchallenge.TheuniqueabilityofXTpclocatorsto

collapse(forportability)andexpand(forgreatersensitivityandfullfunctionality)isunparalleledin

theindustry.



Inthedesignourlocators,Schonstedthasincorporatedmorethansixtyyearsofexperiencein

producingtheworld'sfinestlocatingproductsforaerospace,militaryandcivilianapplications.All

Schonstedtproductsaremanufacturedfollowinghighstandardsofreliability,durabilityand

modes.



AutomaticandManualGain



XTpcreceivershavetheabilitytooperateinautomaticgainmodeorinmanualgainmode.Inthe

automaticgainmode,thesensitivityofthereceiverisadjustedautomatically,basedonthestrength

ofthedetectedsignal,toproducearelativelyconstantandstrongsignalstrengthindication.Inthe

manualgainmode,theuserhastheabilitytoadjustthesensitivityupordowntosuitdifferent

locatingscenarios.



DirectionalIndication



XTpcreceiversareequippedwithdirectionalindicators.Thesevisualandaudibleindicatorshelpthe

userlocatethepipeorcablebyshowingwhichdirectionhe/sheshouldmoveinordertogetcloserto

thetarget.TheseindicatorsarenotavailableintheSondemode.



DepthMeasurement



XTpcreceivershavetheabilitytomeasuretheapproximatedepthofthetargetpipeorcablebeing

traced.Thebottomtipofthereceivermusttouchthegroundwhendepthmeasurementismade,and

bestresultsareobtainedwhenthereceiverisinafullyextendedposition.Depthmeasurements

shouldonlybemadewhenthedirectionalindicationsaysthatthetargetisdirectlybelowthereceiver

andthesignalstrengthisadequate.SpecialconsiderationsarerequiredfortheSondemode(see

SECTIONVIII:OPERATINGRECOMMENDATIONSfordetails).



AutomaticandManualOutputPower



ThetransmittersoftheXTpclineofpipeandcablelocatorsdeliverpowertothe"load"connectedto

them.Intheconductivemode,theloadisthecircuitformedbythecableorpipebeingtraced,the

soilreturn,andthegroundstake.Intheinductiveclampandinductivemodes,theloadsarethe

clampandtheantenna,respectively.Theinductiveclampandinductivemodesrequirethemaximum

powerthatthetransmittercandeliver.Therefore,thetransmitterautomaticallyoperatesat

maximumpoweroutput,andthereisnoneedformanualpoweradjustment.



Intheconductivemode,thepowerdeliveredtotheloadishighlydependentontheexternal

elements(soil,typeofconductor,stakeplacements,etc.).Insomecases,morepowerisdesiredto

achievemoredistanceordepth;inothercases,lesspowerisdesiredtoavoidbleedingtonearby

conductors.Therefore,whileintheconductivemode,theuserhastheabilitytoadjusttheoutput

powermanually(seeSECTIONIII:OPERATINGCONTROLS/Transmitterfordetailsonhowtoadjust

theoutputpower).



TransmitterCurrentMeasurement



Whenoperatingintheconductivemode,transmittersoftheXTpclineofpipeandcablelocators

measureanddisplaytheamountofcurrentflowingintotheutilitybeingtraced.Thisisveryusefulin

determininghowgoodacircuithasbeenestablishedbytheoperator,whetherornotsome

improvementsshouldbemadebyrelocatingthegroundstake,orifthemetaltometalcontactofthe

conductiveclipsneedsimprovement.Alowcurrentreadingcanindicateapoortraceconductor,

poorsoilconductivity,orpoorgroundstakecontact/placement.Highercurrentreadingsindicatea

bettercircuitandabetterchanceattracinglongdistancesanddeepconductors.



Ifthecurrentreadingislow,tryimprovingtheconnectiontoseeifthecurrentincreases(checkthe

cables,clips,andgroundstake;wettheground;cleanrustordirt;etc.).Often,thereasonforthelow

currentisthesoilitself(sandyorverydry)and/orthecompositionofthepipeorcablethatisbeing

traced(castironpipes,rustedorbrokenwires,heavyinsulationtoground,etc.).Ifanimproved

connectioncannotbemade,theremaybeasmallamountofcurrentstillcirculatinginthecircuit.Try

increasingtheoutputpowermanuallyand/orincreasethegainonthereceiver.



Note:Iftheconductiveclipsarepluggedin,thetransmitterprovidedwiththeXTpc+model(theTx5)

willmeasuretheresistanceandanyACorDC voltagethatisbetweentheconductiveclipterminals

uponpoweringup.Ifavoltageispresent,itmustberemovedbeforeproceedingtotheconductive



modeofoperation.Theresistancemeasurementprovidesanadditionalindicationofthequalityof

thelocatingcircuit.



TransmitterTimeOut



ThetransmittersoftheXTpclineofpipeandcablelocatorswillturnthemselvesoff,underthe

conditionslistedbelow,toprotectthebatteryfromanextremelydeepdischarge:



A)Alltransmitters:



WhenthebatteryvoltagehasreachedacriticallylowlevelandthechargerIS NOT

pluggedin.Thislowvoltagecutoffwilloccurregardlessofthetimeoutconditionslisted

below.



B)AlltransmittersEXCLUDING theTx5:



1)Thecharger,conductiveclips,inductiveclamporinductiveantennaARENOT

pluggedin.Inthiscase,thetimeoutis15minutesfromthelasttimethepowerwas

turnedonorabuttonwaspressed.



2)Theconductiveclips,theinductiveclamp,ortheinductiveantennaAREpluggedin.

Inthiscase,thetimeoutis4hoursfromthelasttimethepowerwasturnedon,a

SECTIONIII:OPERATINGCONTROLS



Theproductcontrolsaredesignedtobeintuitiveandrequireaminimumoftrainingforeffectiveuse.

Thereceivercaneasilybeoperatedwithonehand.Thetransmitterautomaticallyrecognizeswhich

accessoryispluggedin,requiringnoadjustmentsintheinductiveandinductiveclampmodes.



Receiver



A)AllModels:



ON/VOLUME‐Thisswitchpowersonthereceiverandautomaticallysetsthevolume

toHigh.AdditionaldepressionsofthisswitchwillcyclethevolumethroughOff(no

sound),Medium,andHighsettings.



OFF‐Thisswitchremovespowerfromthereceiver.



UP/DOWNArrows‐Whenthereceiverisoperatinginmanualgainmode,pressingthe

UPorDOWNarrowswillincreaseordecreasethegainfromitscurrentsetting.When

thereceiverisoperatingintheautomaticgainmode,thefirstpressoftheUPor

DOWNarrowwillswitchthereceivertothemanualgainmode.



AUTO‐Whenthereceiverisoperatinginthemanualgainmode,pressingtheAUTO

buttonwillswitchthereceivertooperateintheAutomaticgainmode.Inthismode

thereceiveradjustsitssensitivityasafunctionofthestrengthofthedetectedsignal.



DEPTH‐Whentheproperconditionstomeasuredeptharepresent,pressingthis

switchwilldisplaythetarget'sdepthontheLCD(afteradelayof2.0seconds).The

depthwillcontinuetobedisplayedontheLCD,alongwiththeword"DEPTH",foras

longastheswitchisdepressed.Iftheswitchispressedandquicklyreleased,the

depthwillshowontheLCDmomentarily.TheXTpccanbefactorysettodisplaydepth

infeetandinchesorinmeters.Ifthedepthcannotbedeterminedduetoaweakor

noisysignaltheLCDwillshow3dashes"‐‐‐".



SONDE‐Ifthesondemodeisavailableandthereceiverisnotoperatinginsonde

mode,pressingthisswitchwillcausethereceivertogotothesondemodeof

operation.Ifthereceiverisalreadyoperatinginsondemode,pressingthisswitchwill

causethereceivertostopthesondemodeofoperation.
