Additional฀Notes

•฀ Sensitivity฀mode฀selection฀–฀general฀guidelines:

฀ •฀ Start฀out฀at฀maximum฀sensitivity฀(฀฀฀฀฀฀฀฀)฀until฀the฀receiver฀finds฀the฀circuit฀under฀

test.฀If฀the฀receiver฀is฀too฀sensitive,฀then฀reduce฀the฀sensitivity฀using฀the฀฀฀฀฀฀฀

฀ ฀ button฀until฀the฀receiver’s฀display฀does฀not฀peg฀at฀“99”฀continuously.

฀ •฀ Use฀฀฀฀฀฀฀฀฀฀฀mode฀for฀tracing:฀(a)฀in฀closed฀circuits฀while฀using฀the฀outlet฀plug฀

adapter฀(rather฀than฀the฀25’฀lead฀and฀a฀remote฀return฀path฀setup),฀(b)฀in฀open฀

circuits,฀(c)฀underground,฀(d)฀and฀anywhere฀else฀more฀signal฀detection฀is฀needed.฀฀

฀ •฀ Use฀฀฀฀฀฀฀฀฀฀mode฀to฀reduce฀the฀level฀of฀sensitivity฀if฀the฀highest฀sensitivity฀range฀

has฀signal฀saturation฀(display฀is฀pegging฀at฀“99”฀continuously).

฀ •฀ Use฀฀฀฀฀฀฀฀mode฀for฀tracing฀(a)฀in฀closed฀circuits฀while฀using฀the฀25’฀lead฀and฀a฀

remote฀return฀path,฀(b)฀and฀when฀previous฀mode฀has฀signal฀saturation฀of฀“99.”฀฀

฀ •฀ Use฀Breaker฀฀฀฀฀฀฀฀mode฀for฀(a)฀identifying฀circuit฀breakers฀and฀fuses,฀(b)฀

pinpointing฀individual฀wires฀from฀a฀bundle,฀(c)฀and฀when฀previous฀mode฀has฀

signal saturation.

•฀ Receiver฀Orientation

฀ •฀ The฀indication฀of฀received฀signal฀intensity฀depends฀on฀how฀the฀receiver฀is฀pointed฀

in฀relation฀to฀the฀source฀of฀the฀signal.฀If฀the฀receiver฀is฀pointed฀away฀from฀the฀

signal฀source฀then฀there฀will฀be฀a฀low฀value฀indicated฀on฀the฀receiver.฀If฀the฀

receiver฀is฀rotated฀about฀the฀axis฀of฀main฀antenna฀sensitivity,฀the฀signal฀varies฀in฀

strength฀as฀the฀antenna฀is฀pointed฀at฀and฀then฀away฀from฀the฀circuit฀being฀traced.฀฀

฀ •฀ Therefore,฀rotate฀the฀receiver฀over฀the฀wire฀being฀traced฀until฀the฀highest฀reading฀

is฀displayed.฀If฀during฀tracing,฀the฀signal฀is฀reduced,฀the฀wire฀may฀have฀changed฀

directions฀(e.g.฀from฀horizontal฀travel฀across฀a฀wall฀to฀vertical฀travel฀up฀a฀wall).฀฀

Rotate฀the฀receiver฀to฀find฀the฀strongest฀signal฀again.฀฀

฀ •฀ Use฀the฀back฀of฀the฀receiver฀to฀sweep฀the฀wall฀or฀floor฀and฀determine฀the฀circuit’s฀

general฀location.฀Use฀the฀nose฀of฀the฀receiver฀to฀pinpoint฀its฀location.

฀ •฀ Steel฀conduit฀attenuates฀(weakens)฀the฀signal฀radiating฀from฀the฀wires฀inside฀the฀

conduit.฀Aluminum฀conduit฀significantly฀attenuates฀the฀signal.฀So,฀the฀receiver฀

should฀be฀set฀at฀a฀higher฀sensitivity฀and฀may฀need฀to฀be฀placed฀closer฀to฀the฀

circuit฀to฀obtain฀a฀stronger฀signal฀detection.฀฀

Theory of Operation

The฀tracer฀consists฀of฀a฀transmitter฀and฀a฀receiver.฀The฀transmitter฀produces฀a฀unique฀

signal฀onto฀the฀circuit฀to฀be฀traced.฀The฀receiver฀detects฀this฀unique฀signal฀when฀placed฀in฀

the฀proper฀orientation฀to฀the฀wires฀being฀traced฀or฀breakers฀being฀identified.฀The฀receiver฀

provides฀a฀numeric฀value฀and฀a฀variable฀pitch/tone฀that฀increase฀as฀the฀signal฀becomes฀

stronger.

The฀transmitter฀sends฀a฀32฀kilohertz,฀fixed-amplitude,฀time-modulated฀signal฀that฀injects฀a฀

voltage฀onto฀the฀circuit฀to฀be฀traced,฀which฀then฀induces฀an฀electromagnetic฀field฀onto฀the฀

circuit.

Whether the circuit is open or closed greatly affects the strength of the electromagnetic

field.

In฀an฀open฀circuit,฀no฀current฀can฀flow,฀so฀the฀electromagnetic฀field฀produced฀is฀much฀

weaker.฀However,฀in฀a฀closed฀circuit,฀the฀injected฀voltage฀induces฀a฀current฀flow,฀which฀

produces฀a฀much฀stronger฀electromagnetic฀field.฀This฀is฀the฀optimal฀method฀for฀tracing฀as฀

this฀much฀stronger฀signal฀allows฀the฀receiver฀to฀detect฀it฀from฀a฀greater฀distance฀away฀from฀

the฀circuit฀being฀traced.฀฀

Here฀are฀some฀examples฀of฀Open/Closed฀Circuits:

Remote฀Return฀Path

Electromagnetic฀fields฀radiate฀counter-clockwise฀in฀relation฀to฀the฀current฀flow.฀For฀

example,฀current฀flows฀out฀on฀a฀hot฀conductor฀and฀returns฀on฀the฀neutral.฀This฀change฀in฀

opposite฀current฀flow฀also฀creates฀opposing฀magnetic฀fields.฀So,฀when฀these฀two฀opposing฀

conductors฀are฀close฀together,฀the฀two฀magnetic฀fields฀tend฀to฀cancel฀each฀other฀out.฀This฀

canceling฀effect฀diminishes฀the฀circuit’s฀ability฀to฀radiate฀the฀transmitter’s฀strong฀signal฀

making฀it฀more฀difficult฀for฀the฀receiver฀to฀detect฀the฀signal.฀฀

To฀avoid฀the฀canceling฀effect฀of฀the฀opposing฀magnetic฀fields฀and฀optimize฀the฀

transmitted฀signal,฀the฀conductor฀to฀be฀traced฀should฀be฀separated฀from฀the฀return฀

conductor฀by฀utilizing฀a฀remote฀return฀path.฀฀

The฀simplest฀method฀is฀to฀use฀the฀25’฀test฀lead฀to฀connect฀to฀a฀remote฀return฀path,฀such฀

as฀a฀neutral฀or฀ground฀from฀another฀circuit฀or฀a฀water฀pipe.฀When฀identifying฀breakers,฀

the฀hot฀and฀neutral฀are฀already฀separated฀at฀the฀electrical฀panel฀so฀the฀use฀of฀the฀AC฀

outlet adapter is sufficient.

If฀unsure฀that฀the฀remote฀return฀path฀chosen฀is฀a฀good฀one,฀use฀a฀multimeter฀to฀measure฀

the฀resistance฀between฀the฀circuit฀neutral฀and฀the฀remote฀return฀path.฀If฀>100Ω,฀a฀

different฀return฀path฀should฀be฀selected.

Applications

Pre-test Operation

Prior฀to฀finding฀a฀breaker฀or฀tracing฀a฀circuit,฀it฀is฀good฀practice฀to฀test฀the฀receiver฀by฀

holding฀it฀near฀the฀powered฀transmitter฀or฀inductive฀clamp.฀A฀numeric฀indication฀of฀“99”฀

and฀strong฀audible฀sound฀ensures฀that฀it฀is฀working฀properly.฀฀

Locating Circuit Breakers and Fuses

Applications฀include฀identifying฀the฀breaker฀that฀protects฀the฀circuit฀under฀test,฀finding฀the฀

correct฀breaker฀to฀de-energize฀the฀circuit,฀and฀labeling฀a฀breaker฀panel.

1)฀฀ Connect฀the฀transmitter฀to฀the฀circuit฀that฀needs฀to฀be฀identified฀and฀power฀it฀on.฀฀

฀ The฀procedure฀is฀the฀same฀whether฀the฀circuit฀is฀energized฀or฀de-energized.฀But,฀a฀฀

฀ much฀stronger฀signal฀is฀produced฀using฀an฀energized฀(closed)฀circuit.

2)฀฀ Turn฀on฀the฀receiver฀and฀go฀to฀the฀panel.฀฀

฀ a)฀฀ If฀more฀than฀one฀panel฀exists,฀set฀the฀receiver฀to฀฀฀฀฀฀฀฀฀฀mode฀and฀touch฀the฀nose฀

to฀each฀panel฀cover฀until฀the฀panel฀with฀the฀strongest฀signal฀is฀identified.฀฀

฀ b)฀ If฀the฀receiver฀is฀detecting฀more฀than฀one฀panel฀with฀a฀strong฀signal,฀reduce฀the฀

sensitivity฀range฀and฀repeat฀the฀step฀above.

3)฀฀ Open฀the฀panel฀cover,฀set฀the฀receiver฀to฀Breaker฀฀฀฀฀฀฀mode.฀The฀receiver฀should฀be฀

positioned฀on฀its฀side฀to฀orientate฀the฀antenna฀properly.฀

4)฀฀ Slide฀the฀nose฀of฀the฀receiver฀down฀each฀breaker฀in฀the฀panel.฀The฀breaker฀with฀the฀

highest฀numeric฀reading฀is฀the฀correct฀breaker.฀฀฀

฀ ฀ If฀two฀or฀more฀breakers฀have฀the฀same฀numeric฀values,฀tip฀the฀nose฀of฀the฀

receiver฀up฀and฀then฀down฀at฀45º฀angles฀and฀note฀the฀numeric฀values฀on฀each฀

of฀the฀questionable฀breakers.฀Only฀the฀correct฀breaker฀will฀show฀a฀strong฀signal฀

in฀all฀positions.฀Or,฀pull฀the฀panel฀cover,฀and฀place฀the฀nose฀on฀each฀of฀the฀

individual฀hot฀wires฀for฀a฀more฀certain฀determination.

5)฀฀ When฀the฀correct฀breaker฀is฀tripped฀(opened),฀the฀signal฀will฀drop฀significantly.฀And,฀

the฀฀฀฀฀will฀disappear฀from฀the฀receiver’s฀display.฀The฀฀฀฀฀LED฀on฀the฀transmitter฀will฀

also turn off.

Tracing Wires

Applications฀include฀finding฀the฀locations฀of฀cable฀runs฀and฀identifying฀other฀devices฀and฀

loads฀on฀the฀circuit.

1)฀฀ Connect฀the฀transmitter฀to฀the฀circuit฀to฀be฀traced฀and฀power฀it฀on.

฀ a)฀ For฀optimal฀tracing,฀leave฀the฀circuit฀energized฀to฀create฀a฀closed฀loop.฀

฀ b)฀฀ If฀the฀circuit฀is฀de-energized,฀then฀connect฀transmitter฀to฀the฀neutral฀and฀ground฀

conductors to create a closed loop.

2)฀฀ Turn฀on฀the฀receiver฀and฀use฀the฀default฀maximum฀sensitivity฀(฀฀฀฀฀฀฀฀฀).

3)฀฀ Starting฀several฀feet฀from฀the฀transmitter,฀use฀a฀sweeping฀motion฀and฀the฀back฀of฀the฀

receiver฀to฀find฀the฀strongest฀signal฀location฀behind฀the฀wall,฀above฀the฀ceiling,฀or฀under฀

the฀floor.฀฀

฀ a)฀฀ If฀the฀signal฀is฀too฀strong,฀reduce฀the฀sensitivity฀range.฀฀

฀ b)฀฀ If฀the฀signal฀is฀too฀weak,฀utilize฀a฀remote฀return฀path฀for฀the฀transmitter.฀Then,฀reduce฀

the฀sensitivity฀range฀on฀the฀receiver฀and฀repeat฀step฀#3.

4)฀฀ Continue฀following฀the฀highest฀reading฀until฀the฀end฀of฀the฀circuit฀is฀found.฀฀

Applications฀include฀locating฀dead฀circuits,฀finding฀the฀source฀of฀an฀open฀(broken฀point)฀in฀

a฀hot/neutral/ground฀conductor,฀and฀determining฀the฀end฀of฀a฀circuit฀run.

1)฀฀ Connect฀the฀transmitter฀to฀the฀open฀circuit฀and฀power฀it฀on.

2)฀฀ Turn฀on฀the฀receiver฀and฀use฀the฀default฀maximum฀sensitivity.

3)฀฀ Starting฀several฀feet฀from฀the฀transmitter,฀use฀a฀sweeping฀motion฀and฀the฀back฀of฀the฀

receiver฀to฀find฀the฀strongest฀signal฀location฀behind฀the฀wall,฀above฀the฀ceiling฀or฀

under฀the฀floor.฀฀

฀ a)฀฀ If฀the฀signal฀is฀too฀strong,฀reduce฀the฀sensitivity฀range.฀฀

฀ b)฀฀ If฀the฀signal฀is฀too฀weak,฀connect฀one฀lead฀of฀the฀transmitter฀into฀the฀open฀conductor฀

and฀connect฀the฀other฀lead฀to฀a฀remote฀return฀path.฀Then,฀repeat฀step฀#3.

4)฀฀ Continue฀following฀the฀highest฀reading฀until฀the฀signal฀starts฀to฀fall฀off.฀This฀is฀the฀

pinpoint฀the฀open฀on฀the฀circuit.฀

If฀the฀open฀is฀not฀found฀after฀tracing฀the฀length฀of฀the฀run,฀the฀conductor฀may฀be฀capacitively฀

coupled.฀This฀condition฀causes฀a฀signal฀bleed-off฀onto฀the฀other฀adjacent฀conductors.฀To฀

remove฀this฀effect,฀ground฀the฀adjacent฀conductors฀and฀minimize฀the฀distance฀between฀the฀

transmitter฀connection฀and฀the฀open.฀

1)฀฀ Connect฀the฀transmitter฀to฀the฀shorted฀circuit฀and฀power฀it฀on.

฀ a)฀ One฀lead฀should฀be฀connected฀to฀the฀faulted฀conductor฀and฀the฀other฀lead฀to฀

ground.

฀ b)฀ If฀the฀ground฀fault฀is฀in฀metallic฀conduit,฀then฀the฀conduit฀is฀the฀ground.

฀ c)฀ If฀possible,฀ground฀the฀adjacent฀conductors.

2)฀฀ Turn฀on฀the฀receiver฀and฀use฀the฀default฀maximum฀sensitivity฀(฀฀฀฀฀฀฀฀฀฀).

3)฀฀ Starting฀several฀feet฀from฀the฀transmitter,฀use฀a฀sweeping฀motion฀and฀the฀back฀of฀the฀

receiver฀to฀find฀the฀strongest฀signal฀location฀behind฀the฀wall,฀above฀the฀ceiling,฀or฀

฀ c)฀฀ If฀the฀signal฀is฀too฀strong,฀reduce฀the฀sensitivity฀range.฀฀

฀ d)฀ If฀the฀signal฀is฀too฀weak,฀connect฀one฀lead฀of฀the฀transmitter฀into฀the฀open฀conductor฀

Tracing Underground

These฀circuit฀tracers฀are฀not฀underground฀cable฀locators.฀But,฀in฀some฀environments฀they฀

can฀be฀used฀to฀trace฀buried฀cables,฀conduit,฀or฀metal฀pipe.

1)฀฀ Connect฀the฀transmitter฀to฀the฀circuit฀to฀be฀traced฀and฀power฀it฀on.

฀ a)฀ If฀possible,฀create฀a฀closed฀circuit฀by฀grounding฀the฀other฀end.

Inductive Clamp Applications

WARNING: ฀The฀clamp฀does฀not฀have฀any฀indicators฀to฀sense฀if฀a฀circuit฀is฀

energized.฀The฀line฀energized฀feature฀(฀฀฀฀฀)฀on฀the฀receiver฀only฀works฀with฀the฀transmitter฀

(TR-955).฀฀

The฀inductive฀clamp฀is฀powered฀solely฀by฀the฀battery฀pack.฀It฀generates฀its฀own฀specific,฀

time฀modulated฀signal,฀and฀by฀transformer฀action,฀couples฀that฀signal฀onto฀the฀energized฀or฀

de-energized฀circuit฀to฀be฀traced.฀฀

Always฀disconnect฀the฀battery฀pack฀from฀the฀clamp฀when฀not฀in฀use฀to฀conserve฀battery฀

power.

For฀the฀clamp฀to฀propagate฀a฀signal฀onto฀the฀circuit฀to฀be฀traced,฀the฀circuit฀must฀be฀closed฀

at฀the฀end฀where฀the฀clamp฀is฀applied,฀at฀a฀minimum.฀To฀maximize฀the฀signal฀produced,฀

both฀ends฀of฀the฀circuit฀should฀be฀closed฀to฀create฀a฀complete฀loop.฀Refer฀to฀the฀diagrams฀

for proper setup.

Three฀typical฀applications฀where฀the฀inductive฀clamp฀may฀be฀used฀in฀replace฀of฀the฀

transmitter:

•฀ Identifying฀downstream฀loads฀from฀a฀breaker

•฀ Tracing฀conduit

•฀ Tracing฀industrial฀control฀circuits

Page 19

Identifying฀downstream฀loads฀from฀a฀breaker.

1)฀฀ Remove฀the฀panel฀cover฀and฀clamp฀around฀the฀hot฀wire฀of฀the฀energized฀(closed)฀circuit.

฀ •฀ To฀maximize฀the฀signal,฀close฀the฀far฀end฀of฀the฀circuit฀by฀plugging฀in฀and฀turning฀

฀ ฀ ฀ on฀a฀work฀light฀or฀other฀load฀into฀the฀furthest฀outlet;฀hence,฀making฀a฀complete฀

loop.

2)฀฀ Hang฀the฀battery฀pack฀onto฀the฀panel฀with฀the฀magnetic฀strap.

3)฀฀ Plug฀the฀clamp฀into฀the฀battery฀pack.

4)฀฀ Set฀the฀receiver฀to฀the฀highest฀sensitivity฀mode฀(฀฀฀฀฀฀฀฀)฀and฀trace฀the฀circuit฀to฀the฀furthest฀

outlet฀while฀identifying฀all฀outlets฀and฀loads฀connected฀to฀the฀circuit.฀If฀the฀Receiver฀is฀

฀ saturated,฀reduce฀the฀sensitivity฀range.

Tracing฀Conduit.

1)฀฀ Clamp฀around฀the฀metallic฀conduit฀to฀be฀traced.฀If฀possible,฀ground฀the฀far฀end฀of฀the฀

conduit฀to฀close฀the฀loop.฀This฀can฀be฀created฀using฀the฀25’฀lead฀and฀alligator฀clips฀to฀clip฀

onto฀the฀end฀of฀the฀conduit฀or฀electrical฀box฀with฀one฀clip฀and฀a฀remote฀neutral฀or฀water฀

pipe฀with฀the฀other฀alligator฀clip.

2)฀฀ Hang฀the฀battery฀pack฀onto฀the฀panel฀or฀conduit฀with฀the฀magnetic฀strap.

3)฀฀ Plug฀the฀clamp฀into฀the฀battery฀pack.

4)฀฀ Set฀the฀receiver฀to฀the฀highest฀sensitivity฀(฀฀฀฀฀฀฀฀)฀mode฀and฀trace฀the฀conduit.฀If฀the฀

Receiver฀is฀saturated,฀reduce฀the฀sensitivity฀range.

Tracing฀industrial฀control฀circuits.

1)฀฀ Ensure฀that฀the฀circuit฀is฀energized฀(closed฀at฀the฀panel)฀at฀a฀minimum.฀To฀maximize฀the฀

signal,฀close฀the฀other฀end฀of฀the฀circuit฀by฀turning฀on฀a฀load,฀such฀as฀a฀motor฀or฀pump.

2)฀฀ Clamp฀around฀the฀hot฀wire฀of฀this฀energized฀(closed)฀circuit.

3)฀฀ Use฀the฀magnetic฀strap฀to฀hang฀the฀battery฀pack฀onto฀the฀panel฀or the฀motor฀control฀

cabinet.

4)฀฀ Plug฀the฀clamp฀into฀the฀battery฀pack.

5)฀฀ Set฀the฀receiver฀to฀the฀highest฀sensitivity฀(฀฀฀฀฀฀฀฀)฀mode฀and฀trace฀the฀circuit฀to฀the฀other฀

end.฀If฀the฀receiver฀is฀saturated,฀reduce฀the฀sensitivity฀mode.

Battery Replacement

Note:฀฀Use฀only฀good฀quality฀alkaline฀batteries฀for฀maximimum฀operating฀life.฀

Always฀replace฀with฀a฀complete฀set฀of฀new฀batteries฀of฀the฀same฀type.฀

Remove฀batteries฀as฀soon฀as฀they฀become฀exhausted฀to฀avoid฀

damage฀due฀to฀leakage.

Transmitter:

Ensure฀that฀the฀test฀leads฀are฀removed฀from฀the฀output฀

jacks฀and฀the฀circuit฀under฀test.

1)฀฀ Remove฀the฀battery฀cap฀by฀loosening฀the฀screw.

2)฀฀ Replace฀batteries฀with฀(4)฀new฀AA฀batteries.

3)฀฀ Re-fit฀cap฀and฀re-tighten฀the฀screw.
