Transmitter Operations
There.are.three.different.methods.of.applying.the.transmitter’s.locating.signal.to.
the.target.conductor:.Direct.Connection,.3M™.Dynatel™.Dyna-Coupler.Clamp,.
and.Induction.

Direct Connection

This.is.the.preferred.mode.of.operation.because.the.transmitter.is.conne cted.
directly.to.a.metallic.portion.of.the.target.conductor.(hydrant,.meter,.riser,.
valve,.sheath,.or.tracer.wire).
1.. .While.the.transmitter.is.off,.plug.the.direct.connect.cable.into.the.output.
jack.of.the.transmitter.
2.. Attach.the.red.lead.of.the.direct.connect.cable.to.the.target.conductor.
3.. .Extend.the.black.lead.as.far.as.possible.from.the.target.conductor.at.a.right.
angle.(90.degrees).to.the.suspected.path.of.the.target.
4.. Insert.the.external.ground.rod.and.attach.the.black.lead.of.the.transm itter.
5.. .Turn.the.transmitter.ON.by.pressing.the.frequency.button..Select.8.kHz,.
82.kHz,.or.both.(8.K.and.82.K.will.flash.on.the.display).
6.. .An.audible.tone,.indicating.the.continuity.of.the.signal.path.will.sound.for.
10.seconds.and.the.output.current.will.display.in.mA.
. a.. Solid.tone.=.Good.signal.
. b.. Fast.Beep.=.Moderate.signal.
. c.. Slow.Beep.=.Minimal.signal.
. d.. No.tone.=.Poor.signal
7.. .The.frequency.will.flash.alternately.with.the.current.of.the.target.conductor.
on.the.display.
8.. Trace.the.signal.path.with.the.receiver..(See.Receiver Operations,.page 8.)

3M Dynatel Dyna-Coupler Clamp

If.a.direct.connection.to.the.target.facility.is.not.possible,.use.the.Dyna-Coupler.
clamp.to.apply.the.locating.frequency.on.the.metallic.target.conductor..In.order.
to.trace.a.target.using.the.Dyna-coupler.method,.both.ends.of.the.target.must.be.
well.grounded.
1.. .While.the.transmitter.is.off,.attach.the.coupler.cable.to.the.Dyna-Coupler.
clamp.and.plug.it.into.the.output.jack.of.the.transmitter.
2.. .Clamp.the.Dyna-coupler.around.the.metallic.target..The.jaws.of.the.coupler.
must.be.fully.closed.
3.. Select.8.kHz.or.82.kHz.on.the.transmitter.by.pressing.the.frequency.key.
4.. Select.High.Output.level.for.the.best.signal-to-noise.ratio.
5.. Trace.the.signal.path.with.the.receiver..(See.Receiver Operations,.page 8.)
