Operation

FunctionalTest

Turnthereceiveronandcheckthat:

1. TheIndicatingLEDisONandRed.

2. TheLowBatteryLEDisOFF.

Ifeitheroftheseconditionsdoesnotexist,replacethebattery

Plugthetransmitterintoalivesocketandmovethereceiverscanningheadoverthefaceofthe

transmitter.Thefrequencyofthebeepingshouldbecomeveryrapidorchangetoacontinuous

tone.TheIndicatingLEDshouldturnGreenwhenthescanningheadisdetectingasignal

”hotspot”(thisisgoodpracticeforscanningsincetheindicationissimilartofindingthecorrect

circuitbreakeratthepanel.)



SettingMaximumSensitivity

Beforeperformingascan,settheunitformaximumsensitivity.Tomaximizesensitivity:After

poweringtheunitON,holdtheunitawayfromthecircuitbreakerpanelandthenpressand

releasetheresetbuttononce.

FindingaCircuitBreaker

Thetransmitterinjectsasignalontothecircuitwhichcanbedetectedbythereceiver.The

receiverwillbeepandtheindicatingLEDwillchangefromredtogreenwhenthestrongestsignal

islocated.Thereceiversensitivityautomaticallyadjuststominimizefalseidentifications.

Pleasefollowtheinstructionsbelowverycarefullywithregardtotheorientationangleofthe

sensorheadtothecircuitbreakerarea.Failuretofollowthesedirectionsexactlycouldleadto

inconclusivetestresults;alsonotetheaccompanyingdiagramforadditionalguidance.

1. Plugthetransmitterintothesocketundertestandthe“correct”LEDswillturnon.

2. GotothecircuitbreakerpanelorfuseboxandswitchONthereceiver.TheIndicatingLED

onthereceiverwilllightredtoindicateautomaticscan.

3. Placethesensingtipincontactwiththe

faceofthecircuitbreakerorfuses.The

sensingtipmustbeflatagainstthecircuit

breakeratalltimesduringthetest.Anytilt

intheangle,inonedirectionoranother,

willaffectthesensor’sabilitytopickupthe

signal.

4. Slowlyrunthesensingtipalongtherowof

circuitbreakers.Maintainaconstantangle

tothebreakersasshown.Thefrequencyof

thebeepingwillincreasetoaveryrapidor

continuoustoneandtheLEDwillturnfrom

redtogreenwhenthereceiverencounters

thebreakerwiththestrongestsignal.

Continuethescanthroughallthebreakers.

5. Repeatthescanoftherowofbreakers.

Witheachsweepthereceiverwill

automaticallyadjustitssensitivityanddisregardweakersignals.

6. Continuescanninguntilthecorrectindication(rapidorcontinuoustoneandgreenLED)is

givenonlywhenthesensingtipisoveronebreakerorfuse.Thisisthebreakerprotecting

thecircuitthatthetransmitterispluggedinto.

7. TurntheselectedcircuitbreakeroffandthereceiverwillreverttoaredLEDdisplay.

8. Returntothetestedsocketandconfirmthatthecorrectbreakerhasbeenselectedby

checkingthattheLEDsonthetransmitterarenolongerON(powerisoff).

9. PressandHoldtheON/OFF/RESETbuttontoturntheReceiverOFF.

Tipsforautomaticscanning

Thereceiverworksbycomparingthestrengthofthesignalreceivedfromonebreakerto

thenext.Observethefollowingforbestresults.

Important:Thefirststrongsignalencounteredmaynotbethestrongestthereis.Donot

stopscanningwhenastrongsignalisfirstencountered.Itisessentialtocontinue

scanninguntilallthebreakersaretestedtoinsurethecorrectbreakerislocated.

Donotletthescanningheadwanderaround.Tooperatewell,theautomaticscanning

memoryneedsaconsistentsignal.

Keeptheredscanningheadatthesameanglerelativetothebreakerorfusesforthe

durationofthetest.

Keeptheheadincontactwiththebreakerduringeachsweeptoensureconsistencyin

theproximityoftheheadtothebreaker.

Testonlythesamesideofeachbreakerduringatest.Payparticularattentiontothis

whentestingaverticallyhungpanelwhichmayhaveneighboringbreakersmountedin

oppositedirections.

Alwaysresetthereceiver(awayfromthedistributionboard)beforechanginganytest

condition.

AlternateScanningTechniques

Duetothedifferingdesignsofcircuitbreakersitmaysometimesbeunclear

fromtheaboveprocedurewhichoftwobreakersthestrongestsignal

comesfrom,particularlyifitappearstocomefromaboundaryarea

betweentwoadjacentbreakers.Intheeventofthisoccurring,oneofthe

followingvariationsshouldenableclearidentification.

A:Resetthereceiverandscanthebreakersontheoppositesideofthe

switch.Thestrongestsignalmaybefoundatthetopofthebreaker.

B:Resetthereceiverandscanthebreakersata90°angletotheoriginal

scan.Atsomepointastrongersignalwillbefound;scanatthenew

angle.

ReceptacleWiringTest

1. PlugtheTransmitter/Receptacletesterintotheoutlet.

2. ThethreeLED’swillindicatecircuitcondition.Thediagramlistsalloftheconditionsthatthe

CB20candetect.TheLED’sinthisdiagramrepresenttheviewfromtheGFCIbuttonsideof

thetransmitter.WhenviewingtheothersideofthetransmittertheLED’swillbeamirror

imageofthoseshownhere.

3. Thetesterwillnotindicatethequalityofthegroundconnection,2hotwiresinacircuit,a

combinationofdefects,orreversalofgroundandneutralconductors.



ReceptacleGFCITest

1. Beforeusingthetester,presstheTESTbuttonontheinstalledGFCIreceptacle,theGFCI

shouldtrip.Ifitdoesnottrip,donotusethecircuitandcallaqualifiedelectrician.Ifitdoes

trip,presstheRESETbuttononthereceptacle.

2. PlugtheTransmitter/Receptacletesterintotheoutlet.Verifythatthewiringiscorrectas

describedabove.

3. Pressandholdthetestbuttononthetesterforatleast8seconds,theindicatorlightson

thetesterwillshutoffwhentheGFCItrips.

4. Ifthecircuitdoesnottrip,eitherthewiringisincorrect,orthewiringiscorrectandtheGFCI

isdefective.
