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)
