1. General information about cable tracing
A cable tracer detects the magnetic or electric field which has been induced to a cable or wire using the transmitter.
Tracing is often affected by other nearby conductors and ducts. We recommend to read this manual carefully prior to
using the CT33 equipment.
CT33 equipment is intended to be used for example:
To locate and track mains cables
To locate and trace telecom cables
To locate shorts in telecom cables
To trace coaxial/antenna cables
To locate floor heating cables
To locate ducts and duct blockages using transmitter sondes
CT33 can be used both indoors and outdoors, and when properly used, it is safe even with mains environment.
Some tracing tasks may require accessories.
In this manual there are two symbols used to describe grounding & earth connection:
This symbol means grounding through constructions, such as grounded pipes, metal chassis, mains wall
socket protective earth connector etc.
This symbol means direct earthing to soil with a ground pick or other similar means so that no other
constructions are involved.

3. CTT33 User interface
Power button:
To turn power on and off. While powering on LED bar briefly
displays software version and after that it displays battery status
with reference to full batteries. When device is on, also a short
press will display battery status similarly.
Battery compartment (on the backside of the enclosure. Lid has screws).
CTT33 uses 6 1.5V LR6 (AA) alkaline batteries. Similar NiZn or NiMH batteries can
be used but they require a separate charger.
Output connectors:
4 mm safety banana jacks for tracing signal output.
BOOST:
Output power selection: When BOOST LED is on,
higher output power is selected.
PULSE:
Output signal mode selection: Signal can be
continuous (default) or slowly pulsed or fast
pulsed. PULSE LED displays which mode is on.
Output mA:
LED bar: Output current display (also software version and
battery status)
Power LED
If power LED blink, batteries are weak.
CT33 User Manual v. X1.0 7
4. Basics on how to use the transmitter
CTT33 transmits 33kHz (32,768Hz) signal always when it is on. The default output power is sufficient for most needs.
If BOOST mode is selected (BOOS LED on) output signal is higher but batteries are also drained faster.
When PULSE LED is on continuously, output signal is continuous. Press PULSE button once or twice to choose 4Hz or
8Hz pulsed signal correspondingly. With receiver pulsed signal is often easier to distinguish from noises. Two pulsed
signal modes enable using the two transmitter method for locating wire cuts.
Feeding cords are used to connect the transmitter to the target. Standard cords are safe when properly used but
safety precaution must be followed all the time when working with live wires. If galvanic connection and feeding is not
possible, inductive signal feeding with a clamp-on transformer may be used instead.
Warnings concerning the transmitter
When operating with mains targets, always use contact proof and right safety class cords and
adapters, and follow safety instructions.
CTT33 transmitter may be connected to max. 230V rms voltage!
If either transmitter output terminal is connected to a live target, dangerous voltage or current
may appear on wires connected to the other output, unless they are properly grounded.
Avoiding interference with telecommunication or electric network is always the responsibility of
the user.
Risk of electric shock: Always disconnect feeding cords before opening the battery lid or
enclosure.

5. CL43 Receiver user interface
Speaker:
Indicates received signal
str
ength; the higher pitch and
volume, the stronger the signal.
(+) and (-) buttons:
(+) long press: power on / off
(+) extended pressing during start-up: makes the LED arc show
firmware version.
(+) releasing press during start-up: makes the LED arc briefly
display battery status and the active operating frequency with one
of the three rightmost LEDs.
(+) and (-) short presses: gain setting up or down, 5 or 7 steps
available depending on connected probe. A beep sound indicates
change of gain, no beep means that maximum or minimum has
been reached.
(-) long press: Initiate change of receiving frequency mode:
1) Press (-) until a beep is heard. Keep it pressed!
2) Press (+) until another beep is heard.
3) See the LED arc: One of the 512/10k/33k LEDs briefly
indicate chosen frequency.
If necessary repeat 1 to 3 to get the right frequency. Connected
pro
be allows choosing only frequencies supported by the probe.
SA05 probe always forces CL43 to 512Hz mode.
Arc of 12 red LEDs:
In
normal operation arc displays
received signal strength with
24 levels. The
512/10k/33k
LEDs display the active
operating frequency when the
frequency is changed or when
a probe is connected to the
CL43 device while power on.
Power LED: Green LED indicates
power
on. LED blinks if battery is weak.
Probe:
Choose
probe according to
the tracing task.
Probe
release
button:
Press here
to remove
the probe.
Batteries:
Batteries are
located under the user
interface cap.

6. Putting the CL43 receiver into use
Batteries:
CL43 receiver uses 3pcs AAA (IEC LR03) alkaline batteries. Compatible
NiZn batteries can be used but they must be recharged in a separate
charger.
To change batteries, turn the user interface cap (1) off and pull the
battery holder (2) out from the tube. Replace old cells with new ones.
Observe battery polarity: (-) poles must be placed against the spring
contacts. Insert the battery holder back into CL43 tube according to the
arrow symbol (3). Turn the user interface cap back on the tube (4).
Connecting /disconnecting probes:
CL43 always requires a probe to operate. To attach a probe, push the
probe connector (1) in to CL43 socket (2) aligned as in the image until
the locking clicks. To remove a probe: Press the release button (3) under
the rubber to release the locking and pull the probe out.
Warnings concerning the receiver
Though it is not possible to get an electric shock via CL43 receiver probes at less than 600V
environment, it is NOT suggested to use CL43 probes so that they touch live targets.
Do not ever let CL43 body touch live targets.
When operating with mains targets, always follow safety instructions.
