Tracer has the capability of tracing unenergized wires, locating open
breakers and locating open wires.

PRECAUTIONS

FOR PERSONAL AND INSTRUMENT PROTECTION

IMPORTANT:

1. Before using any electrical instrument, it should be checked to make
certain it is operating properly.

2. In many instances, you will be working with dangerous levels of
voltages and/or current, therefore, it is important that you avoid
direct contact with any uninsulated, current carrying surfaces.
Appropriate insulated gloves, safety glasses and protective clothing
should be worn.

3. Before attaching anything to the conductor, make sure the voltage
present is not beyond the range of the instrument.

4. When not in use, keep the Instrument in its carrying case.

5. When the R2000 or the T2200 will not be used for a period of time,
remove the battery.

The AT-2000 Advanced Tracing System combines both Current Tracing
and Open Tracing into one versatile tool providing the ability to solve
virtually all your tracing problems.

Having confidence in an instrument is an important part of using the
instrument. All applications are different and special. An understanding of
the system's operation could be the difference between several minutes
or several hours on the job.

Invest time learning the operation of the Advanced Tracer to build
confidence in the unit. Please read this manual carefully. Take the time
to learn how the instrument operates. Test it in a variety of situations.
You will soon have the confidence to use it on a daily basis to solve
problems which were previously unsolvable.

COMPONENT DESCRIPTION

R2000 Receiver

Has two built in detector that are tuned to pick up the 32.768khz signals
generated by any of the other devices in the AT-2000 family: S2300,
S2600, T2200, A2201. The R2000 is designed to display the signal's
strength to enable quick locating of the conductor carrying the signal.

Fig.1

Changing Batteries

The battery compartment on the back of
the R2000 and the T2200 is a new
design that allows you to drop the
battery in and out quickly and easily.
Two holes on the bottom of the
compartment accept the round terminals
of a 9 volt battery. The compartment is
designed to accept the battery 180° and
try again.

Mode Adjustment
Switch

'OPEN' mode is used
for open conductors.
'SHORT' mode is used
on conductors that
make up a complete
circuit.

Using the R2000 Receiver

1. Turn the R2000 'ON' by rotating the thumbwheel and leave it around
position '5'.

2. Move the range switch to x1 (this is the least sensitive setting).

3. Place the mode switch into the appropriate position and aim the
R2000 properly (see illustration below).

4. If there is no indication on the display, increase the sensitivity by
moving the range switch to x10 or x100. The thumbwheel is used as a
fine adjustment to maintain a midrange indication (3-9 LED's).

IMPORTANT: Always try to keep the sensitivity low enough to a
maximum of 9 LED'S on the indicator. Otherwise, you could waste a
lot of time determining the proper signal source - a weak signal may
register 10 LED'S in the x 100 range, but so will a strong signal
(typically the one you want to follow).

5. When tracing, move the R2000 back and forth over the path of the
wire and adjust the sensitivity so that you can see the rise and fall of
the signal level. The strongest signal confirms the path of the wire.

NOTE: The R2000 will experience electromagnetic saturation when held
up against wires carrying more than 500Amps. If this occurs, the signal
strength indicator will go black. To remedy this, simply move the R2000 a
few inches away from the wire.

Fig. 3

In the 'SHORT' mode,
orient Receiver so that
is perpendicular to the
wire.

Example:

Horizontal wire-

thumbwheel should face
up;
Vertical wire- thumbweel
should face either left or
right.

S2300 and S2600 Load Signal Generators (LSG's)

When connected to an energized circuit, the LSG's will rapidly turn them­selves on and off. This causes a slight, periodic current fluctuation that
causes the power line to emit its own, trace-able signal, this signal can
be detected all the way back to the main generator. However, the signal
will not interfere with any sensitive electronic equipment and does not
require power interruption.

S2300- For use on 9 to 300 volts AC or DC circuits only.
S2600- For use on 9 to 600 volts AC or DC circuits only.

Fig.4

Both units are intrinsically safe and have a special 'LOW’ - power setting
used when tracing GFCI- protected circuits.
As their name implies, when connected to a circuit as a load, the LSG's
cause the power line to generate a signal. The signal will be present any­where between the LSG and the power source
(line side or 'upstream') - no signal will be present on wiring on the other
side of the LSG (load side or 'downstream'). For example, an LSG
connected to a circuit breaker will produce no signal on that circuit. It will,
however, cause a signal to be generated between that panel and the

transformer.... and beyond.

NOTE: The signal strength after transformer will decrease according to its stepdown ratio.

Power Selection Switch
Use 'Low' power when
unit is connected to a
GFCI-Protected circuit.
Use 'HIGH' power for all
other applications.

Connections for
Banana Plugs

Are not polarized so it
doesn't matter which
lead gets connected to
power and which to
ground.

LED Indicator
light will blink if properly
connected to an energized
circuit.

Intrinsically safe Fuse
Holder

Pulling out the fuse holder
automatically disconnects
the fuse from the circuit
while shielding the user
from live terminals.

No Battery!
Units receive power from
the circuit they are
connected to.
