toapplyalocatingsignalonthetarget,usetheinductionmethod.Thismethodusesthe
internalcoilofthetransmittertogenerateamagneticfield.
TheInductionPeakmodeofthereceiverisamodeinwhichtheupperantennaofthe
receiveristunedtominimizedistortionfromthemagneticfieldofthetransmitter.

E. Expanded Mode
Whenthethirdringofthespeakericonisdotted
orbrokenand‘xpnd’appearsbelowthespeaker
iconasshown,thereceiverisin“Expanded”
mode.Thismodeisusedforpinpointinga
targetcableorpipe.Theareaofresponseof
thereceivernarrows,allowingthelocatorto
detectverysmallsignalchanges.Pressthe
Speaker Volume Control[2]keytoactivatethe
"Expanded"mode.
8. Depth and Current Estimate
Verifyingthetargetpath,depthandcurrentcanbehelpfultools.
1. Pinpointthecableorpipebeinglocated.
2. Lowerthetipofthereceivertothegroundand
pressDepth[SK].
− Thedepthtothetargetcableorpipeis
displayedintheunitsspecifiedinthereceiver
setupmenu.Theboldcurrentreadingisa
relativecurrentmeasurement.Thisreading
canbecomparedtothecurrentreadingthat
alternatelyflasheswiththefrequencyonthe
transmittertohelpidentifythetargetcable/
pipe.Thehighestrelativecurrentvaluewill
bethetargetcable/pipeandwillcompare
closesttothetransmitterrelativecurrentvalue.
Themilliampreadingisanactualcurrent
measurement.
