INTRODUCTION
This cable locator is a portable instrument designed to detect or trace conduits. It consists of a transmitter and a receiver. The signal generated by the transmitter is a modulated current which generates an electromagnetic field around the conductor connected. This electromagnetic field induces a voltage within the receiving coil of the receiver. Then the induced voltage is amplified, decoded, converted by the receiver, and finally indicated on the receiver screen.
Features:
● Finding cable in wall, line interruption, or short-circuit in a line. ● Tracing a cable that is in soil. ● Detecting fuse or circuit breaker and assigning current circuits. ● Tracing socket or distribution socket that has accidentally been covered by plastering. ● Detecting interruption or short-circuit in floor heating. ● Tracing metallic water and heating piping. ● Various applications in both voltage-free and live systems. - The screen of the transmitter indicates the transmission level, the transmission code, and the foreign voltage.
- The screen of the receiver indicates the reception level and the transmission code. ● Mains voltage detection by using the receiver. ● Automatic and manual sensitivity adjustment of the receiver. ● Acoustic signal indication of the receiver may be turned off.
- Illumination function. ● Automatic power-off.
- Backlight.
Supply list:
- One transmitter.
- One receiver.
- Two test leads.
- Two test leads that have a probe.
- Two alligator clips.
- 1 ground stake.
- One carrying bag.
- One manual.
SAFETY INFORMATION
- Adhere to local and national safety codes. Individual protective equipment must be used to prevent shock and arc blast injury where hazardous live conductors are exposed.
- Do not operate the instrument where explosive (or combustible) gas, vapor or dust is present.
- Use caution when working with voltage above 30V ac rms, 42V peak, or dc. Such voltages pose a shock hazard.
- To avoid electric shock, do not touch any naked conductor with your hands, and do not ground yourself while using the instrument.
- Do not use the instrument if it is damaged or operates abnormally.
- Inspect the test leads for damaged insulation or exposed metal. If a test lead is damaged, replace it with a new one of the same ratings before use.
Before any operation, make sure that the connecting leads used and the electronic load are in good condition.
Measurement in dangerous proximity to electrical installations can only be made when instructed by a responsible electrical specialist. Never work alone.
Keep the instrument dry.
To avoid interference, do not use the instrument where there is an intense environmental electromagnetic field; otherwise, the detection or measurement result may be wrong.
The instrument may only be used on systems complying with the nominal voltages indicated in the technical data section of this manual.
It is recommended to exclusively connect the transmitter from the phase toward the neutral conductor. If the transmitter connection is made from the phase toward the protective conductor, the functional safety of the protective conductor must be tested first, in compliance with DIN VDE 0100. The reason is that when connecting the transmitter from phase toward ground, all parts connected to the earth may be live in the event of an error (if resistance does not comply with the prescriptions).
If the RCD trips when connecting the transmitter (with reference to the protective earth contact PE), a fault current is already active within the installation which generates the RCD tripping when cumulated to the additionally fed current.
The instrument can only be used under those conditions and for those purposes for which it was designed.
Because the instrument's voltage amplitude/value indication is affected by many factors (such as environmental electromagnetic field, the distance between the receiver and the conductor under test, the resistance of the connecting leads, the connection resistance, etc.), do not treat or regard the voltage amplitude/value indicated by the instrument as the actual voltage amplitude/value of the circuit under test.
Do not tamper with the internal circuits of the instrument.
Never short the positive and negative terminals of any battery. Do not place any battery in fire. Do not dismantle or bump any battery.

PRODUCT INSTRUCTION
The instrument consists of a transmitter and a receiver. The transmitter generates an AC signal of a modulated current. The current of the AC signal flows through the connected conductor, generating an electromagnetic field around this conductor. This electromagnetic field induces a voltage in the receiver coils. In the automatic mode and manual mode, the receiver works with three coils and does not depend on the direction of the receiver. A selective and position-dependent search is performed in the selective mode or PINPOINT mode with only one coil. The induced voltage is amplified, decoded, and converted by the receiver and finally indicated on the receiver screen. For any application, ensure that there is a closed loop for the flowing signal in the conductor when connecting the transmitter (see Figure 5).

In the PINPOINT mode, when the longitudinal axis of the receiver is parallel to the line conductor which is connected to the transmitter, and the receiver is above this line conductor (see Figure 6), the signal received by the receiver is at its maximum. The PINPOINT mode is used to accurately locate a line conductor buried under a wall or earth surface.

In the mains voltage detection mode, the receiver can detect a 50Hz - 60Hz electromagnetic field in any direction.
LOCATOR IN COMPLETE CIRCUITS
●1st Possibility (one pole application)
Connect the transmitter to only one conductor. The second conductor is the ground. This arrangement causes a signal current to flow through the conductor and to be transmitted to ground, similar to a radio and receiver. Hereafter, call the above described operation one-pole application.
●2nd Possibility (double-pole application)
Connect the transmitter to the mains. In this condition, the modulated current flows through the phase and then returns to the transmitter via the neutral. There is another possibility for voltage free systems by connecting the transmitter to two line terminals while short-circuiting the other line ends. The complete circuit is created. Then, the transmitter is supplied by the built-in battery. Hereafter, we call this operation double pole application.
Note:
The instrument can only detect or locate lines which are connected correctly in accordance with the physical principle described.
In double-pole application, the PINPOINT mode of the receiver does not work. Do not use the PINPOINT mode in any double-pole application.
IMPORTANT APPLICATIONS
●In open circuits (one pole application) (see Figure 7)
Line interruptions in walls and floors. Finding and tracing of lines, sockets, junction box, switches, etc. For house installations.
The black terminal of the transmitter must be connected to a suitable earth. A typical example is a properly earthed socket. The tracing depth amounts to 2 meters.
Note: The tracing depth depends on the medium and application.
Figure 7
●In complete circuits (double pole application) (see Figure 8)
When detecting short-circuits or during wire sorting, i.e. circuits with or without voltage. Voltage-free circuits are directly supplied by the transmitter battery. In live circuits, the transmitter is mainly supplied by the circuit connected. The transmitter is voltage-proof up to 600V AC/DC.
Example for a complete circuit: Complete circuits are appropriate for: i.e. detecting switches, sockets, etc in live installations.
Note:
- The tracing depth amounts to 0 - 0.5 meter. The tracing depth depends on medium and application.
- Increasing the transmission level from level 1 to level 3 with the " " bit increases the detecting distance of the receiver by a factor of about 4.
- When connecting the transmitter in a live circuit, adhere to local and national safety codes. To avoid electric shock, do not touch any naked conductor with hand or skin.
Figure 8
CARRYING OUT MEASUREMENT
Tracing and locating of lines, sockets, switches and junctions in house installation circuits (one-pole application)
Requirements:
●The circuit must be dead. ●Neutral line and ground must be fully operational. - Connect the transmitter to phase and ground according to Figure 9. ●Carry out this example as described in the application example.
In the one-pole application, lateral circuit branches can also be traced.

Figure 9
Note:
- If the supply cable fed with the signal via the transmitter is located direct parallel to other conductors (e.g. cable duct) or if these conductors are on the signal is also input into the other conductors.
- Increasing the transmission level from level 1 to level 3 with the " " button increases the detecting distance of the receiver by a factor of about
- Setup of the receiver: manual mode, minimal sensitivity. If necessary, adjust the sensitivity of the receiver according to the actual condition during detection. ●Max. tracing depth: about 2 meters.
Locating of line interruptions (one-pole application)
Requirements:
●The circuit must be dead. ●All lines that are not required must be connected to the auxiliary ground in accordance with Figure 10. - Connect the transmitter to one lead and to ground according to Figure 10. ●Carry out this example as described in the application example.
Line interruption in the plastic-sheathed cable.
The ground connected to the transmitter should be earth from a properly earthed socket or a water pipe that is properly earthed.
When tracing line interruption in a multicore cable, note that all remaining leads in plastic-sheathed cable must be grounded in accordance with the regulations. This is required to avoid crosscoupling of the fed signal (by a capacitive effect).
The tracing depth for sheathed cable and conductors are different, because individual leads in the sheathed cable are twisted around themselves.
The transition resistance of a line interruption must be > 100 kΩ. The verification of resistance can be done by using a multimeter.
Systematically circle around the interruption while changing the sensitivity of the receiver. By this means, the line interruption can be located in the end.

Figure 10
Note:
- Increasing the transmission level from level 1 to level 3 with the " " button increases the detecting distance of the receiver by a factor of about
- Setup of the receiver: manual mode, minimal sensitivity. If necessary, adjust the sensitivity of the receiver according to the actual condition during detection. ●Max. tracing depth: about 2 meters.
When locating a line interruption using one transmitter to feed from one conductor end, the location of the line interruption may not be precise in case of bad conditions due to field disturbance. This drawback can easily be avoided by using two transmitters (one from each end) for interruption detection. In this instance, each of the transmitters is set to a different transmission code (e.g., one transmitter is set to code "1", the other transmitter is set to code "6").
Your instrument includes only one transmitter. If you need a second transmitter, you can separately order one or more transmitters from our company.
If the transmitters are connected in accordance with Figure 11, the receiver displays the transmission code "1" at the left side of the line interruption. If you continue further than the interruption, toward the right, the receiver displays the transmission code "6". If the receiver probe is directly at the line interruption, no transmission code is displayed, due to the overlapping of both transmitter signals. The line interruption is located between the displayed codes "1" and "6".
Requirements:
● The circuit must be dead. ● All lines which will not be used must be connected to the auxiliary ground as shown in Figure 11. - Connect the two transmitters as shown in Figure 11. ● Proceed as described in the application example.
The ground connected to the transmitter and to the wires not being used can be an auxiliary ground, the ground contact of a properly earthed outlet, or a properly grounded water pipe.
When carrying out line interruption locating on a multi-wire shielded cable, make sure that all unused wires are orderly grounded. This is required to avoid inductive disturbance (by capacity coupling).
The locating depth for shielded conductors and cables varies, because individual wires within the shield are twisted.
The transition resistance of a line interruption must be > 100 kΩ. Verification of resistance can be done by using a multimeter.
Systematically circle the line interruption by changing the sensitivity of the receiver.
Note:
- Increasing the transmission level from level 1 to level 3 with the "+" button increases the detecting distance of the receiver by a factor of about 3.
- Setup of the receiver: manual mode, minimal sensitivity. If necessary, adjust the sensitivity of the receiver according to the actual condition during detection. ● Max. tracing depth: about 2 meters

LOCATING CIRCUIT BREAKER OR FUSE THAT SUPPLIES AN OUTLET (DUAL-POLE APPLICATION)
Warning: Adhere to local and national safety codes. To avoid electric shock, do not touch any naked conductor with hand or skin.
Refer to Figure 12, connect the red and black terminals of the transmitter to the desired energized AC wall outlet. Make sure that the red terminal of the transmitter is connected to the Live terminal of the outlet and the black terminal of the transmitter is connected to the Neutral terminal of the outlet. The transmitter displays the value of the voltage of the outlet. Set the transmission level of the transmitter to level 1, the transmitter will dis

" as an indication.
Go to the circuit breaker panel box, place the flat top of the pin, the receiver directly onto circuit breaker or fuse (refer to Figure 1). Hold the receiver so that it is perpendicular to the breakers or fuses
as shown. Slowly move the receiver up and down over the rows of breakers or fuses. During this process, if two or more circuit breakers (or fuses) caused the receiver to give signal indication, decrease receiver's sensitivity and then scan slowly all breakers or fuses once more.
When you find the only one circuit breaker or fuse at which the receiver gives signal indication, turn off the circuit breaker (or remove the fuse). If the receiver stops giving audio and visual signal indication and the transmitter displays " instead of a voltage reading, the circuit breaker (or the fuse) is the circuit breaker (or fuse) supplying the outlet. If the transmitter still displays a voltage reading, it means the circuit breaker (or the fuse) is not the circuit breaker (or fuse) that supplies the outlet.
The detection or assignment of the circuit breaker or fuse strongly depends on the wiring realized within the distribution. To obtain a result as precise as possible, the cover should be removed and the supply line to the fuse should be traced.

Note:
- If the circuit breaker panel box is not far from the transmitter, the transmission level of the transmitter must be set to level 1. If the circuit breaker panel box is too far from the transmitter so that it is impossible to perform detection and locating, you should appropriately increase the transmission level of the transmitter according to actual condition.
- Increasing the transmission level from level 1 to level 3 with the "LEVEL" button increases the detecting distance of the receiver by a factor of about 4.
- Setup of the receiver: selective mode, minimal sensitivity.
- Safety cutouts of different manufacturers have different installation positions for magnetic coils. If no evident signal can be detected by the receiver, it is recommended to rotate the receiver clockwise or counterclockwise by 90 degrees.
- To avoid electric shock, do not touch any naked conductor with hand or skin.
Error detection for an electrical floor heating (one-pole application)
Requirements:
The circuit must be dead. A second transmitter is required for this application. Connect the transmitters as shown in Figure 13. Carry out this example as described in the application example. If a shield mat or shield wiring is located above the heating wire, ground connection may exist. If required, separate the shield from ground connection, and remember to restore the ground connection after you finish the detection.
Note:
Increasing the transmission level from level 1 to level 3 with the "LEVEL" button increases the detecting distance of the receiver by a factor of about 4.
- Setup of the receiver: manual mode, minimal sensitivity. If necessary, adjust the sensitivity of the receiver according to the actual condition during detection. Max. tracing depth: about 2 meters.

Locating of short-circuits in conductors (double-pole application)
Requirements:
All circuits within the cable must be dead. Connect the transmitter in accordance with Figure 14. Carry out this example as described in the application example.
Note that the tracing depth for sheathed cable and conductors are different because the individual leads in the sheathed cable are twisted around themselves.
Usually, short-circuit can only be correctly detected when the short-circuit resistance is lower than 20 Ohm. The verification of the short-circuit resistance can be done by using a multimeter. If the short-circuit resistance is more than 20 Ohm, you can try the experiment to detect the error location by means of the line interrupt detection method.
Systematically circle round the interruption by changing the sensitivity of the receiver.
Note:
- Increasing the transmission level from level 1 to level 3 with the "LEVEL" button increases the detecting distance of the receiver by a factor of about 4.
- Setup of the receiver: manual mode, minimal sensitivity. If necessary, adjust the sensitivity of the receiver according to the actual condition during detection. Max. tracing depth: about 0.5 meter.

Figure 14
Tracing installed water and heating pipes (one-pole application)
Requirements:
● The line to be located must be separated from the equipotential bonding. (When you finish tracing water or heating pipes, remember to restore the line's connection which you have disconnected.) - Connect the transmitter in accordance with Figure 15. ● For safety reasons, the electrical system must not be live!
Connect the black terminal of the transmitter to the ground terminal of a properly earthed socket, and connect the red terminal of the transmitter to the conductor to be traced or located. Now the feed can be traced.
Note:
- Increasing the transmission level from level 1 to level 3 with the "LEVEL/ON" button increases the detecting distance of the receiver by a factor of about 4.
- Setup of the receiver: manual mode, minimal sensitivity. If necessary, adjust the sensitivity of the receiver according to the actual condition during detection. ● Max. tracing depth: about 2 meters.

Figure 15
Tracing conductors buried in the soil (single-pole application)
The connection is realized in compliance with Figure 16.
Warning: Ensure that the current circuit is not live.
Note: Make sure that the distance between the connection to the ground and the conductor to be detected is high. If the distance is too short, no definite assignment of the received signal can be made to one conductor. (See Figure 16.)
The max. tracing depth is about 2 meters. The tracing depth strongly depends on the soil characteristics and the instrument's settings.
Set the receiver to automatic mode. Now, search or trace the conductor by means of the signal intensity displayed. When circling the receiver slowly across the conductor to be searched, the displayed values change considerably. The display of the maximum signal intensity is performed directly via the conductor. The signal intensity level decreases with increasing distance of the fed-in signal (transmitter).

Practical application example.
In order to determine all electrical lines of a house within one work process, proceed as follows:
- Remove the bridge in the main distribution between "PE" and "N". Warning: For safety reasons, the system must not be live!
- Connect the transmitter to the system in compliance with Figure 1. Now, the neutral conductor present in the system may be followed.
Note:
- Increasing the transmission level from level 1 to level 3 with the "LEVEL" button increases the detecting distance of the receiver by a factor of about 4.
- Setup of the receiver: manual mode, minimal sensitivity. If necessary, adjust the sensitivity of the receiver according to the actual condition during detection.
●Max. tracing depth: about 2 meters

If the dual-pole application is carried out on multi-wire cables (NYM 3 x1.5mm2), the location depth is widely limited. This is best the go-and-return lines are installed very closely. And as a result, strong distortion of the magnetic field occurs. The electro-magnetic field may not develop at the bottleneck. This limitation can easily be eliminated when using a separate conductor as the return line. This separate conductor allows a larger spreading of the electro-magnetic field. Any conductor or cable reel can be used as separate return conductor.
When tracing the conductors, make sure that the distance between the feeder line and the return line is larger than the location depth. In practical applications, this amounts to approx. 2.0 meters.
For this application, humid walls, plaster, etc. have only an insignificant influence on the location depth.
Requirements:
●The current circuit must not be live. - Connect the transmitter in compliance with Figure 18. ●The distance between the feeder line and the return line must be at least 2.0 to 2.5 meters or more. ●Proceed as described in the application example.
Note:
- Increasing the transmission level from level 1 to level 3 with the "LEVEL/2" button increases the detecting distance of the receiver by a factor of about 4.
- Setup of the receiver: manual mode, minimal sensitivity. If necessary adjust the sensitivity of the receiver according to the actual condition during detection.
●Max. tracing depth: about 2 meters

The reach will be improved when seeking the tension.
If the transmitter is connected to a live line and a neutral line, the signal is conducted on two parallel lines (see Figure 19).
The twisting of the lines can sometimes cause the signals to cancel each other. In this case, the maximum effective detecting radius of the receiver is only about 0.5 meter.
To eliminate the effect pointed out in Figure 19, the connection should be carried out as shown in Figure 20. In this figure, a separate cable is used as the return line, which can increase the effective detecting radius of the receiver to about 2.5 meters or higher. A larger distance return line can be provided through the cable reel.
Pay attention to the distance between the receiver and the line being checked, so that the line can be clearly determined according to the signal indication of the receiver.
Comply with the relevant national and local safety laws and regulations when performing connections on live circuits.
Note:
Increasing the transmission level from level 1 to level 3 with the "LEVEL" button increases the detecting distance of the receiver by a factor of about 4.


Sorting or determination of conductors already installed (double-pole application)
Requirements:
● All circuits within the cable must not be live. ● The lead terminals must be twisted and electrically connected to each other. ● You need several transmitters with different transmission codes. - Connect the transmitter according to Figure 21. ● Carry out this example as described in the application example.
For this application example, please notice that the stripped lead terminals are twisted with each other. The electrical connection between the stripped lead terminals must be good.
If you have only one transmitter, the sorting of the sheathed cable can be done by sequentially reconnecting the transmitter.
Note:
Increasing the transmission level from level 1 to level 3 with the "LEVEL/2" button increases the detecting distance of the receiver by a factor of about 4.

The test is performed in compliance with Figure 22. For this application, no transmitter is required.
Select the mains voltage detection mode with the "NCV" button on the receiver. (When the mains voltage detection mode is selected, the receiver displays the symbol "NCV" as an indicator.) Move the receiver probe close to the cable to be tested, and observe the right to see where it gives a signal indication.
The bargraph display indicating the signal intensity and the signal sound frequency depend on the level of the voltage of the conductor under test, the distance between the receiver and the live conductor, the insulation of the conductor, etc.
The higher the frequency of the signal sound of the receiver, the higher the voltage, or the lower the distance to the conductor.
Warning:
●The signal intensity indicated by the receiver does not necessarily indicate the level and type of the voltage of the conductor under test. The value of a voltage can only be determined by a professional measurement tool such as a multimeter. ●The signal indication of the receiver is affected by the distance between the receiver probe and the conductor under test, the voice of the conductor, the insulation of the conductor, etc. The conductor under test may be live even if the receiver does not give any indication. To avoid electric shock and personal injury, do not touch any conductor with hand or skin. - Before and after each use, verify the receiver's operation by detecting a known energized power socket. Do not use the receiver if it operates abnormally or is damaged.
To avoid interference, do not use the receiver where there is a strong environmental electromagnetic field; otherwise the test result may be wrong.

Store the instrument in a dry place when not in use. Do not stand in an environment with intense electromagnetic fields.
If the instrument fails, check and replace (as needed) the battery and fuse and/or review this manual to verify proper operation.
BATTERY REPLACEMENT
Replacing the battery in the transmitter:
When the battery level indicator on the transmitter display becomes "or when the receiver display shows", the battery in the transmitter is not high enough and you must replace it immediately; otherwise the transmitter will not operate normally or the measurement/detection result may be wrong.
To replace the battery, turn off the transmitter and then disconnect the transmitter from any cable/lead and circuit. Remove the screw on the battery cover of the transmitter and then remove the battery cover. Replace the old battery with a new one of the same type, making sure that the polarity connections are correct. Reinstall the battery cover and the screw.
Warning
To avoid electric shock, turn off the transmitter and then disconnect the transmitter from any cable/lead and circuit before opening the battery cover or case of the transmitter.
Replacing the battery in the receiver:
When the low battery indicator "R" appears on the receiver display, the battery in the receiver is not high enough and you must replace it immediately; otherwise the receiver will not operate normally or the detection result may be wrong.
To replace the battery, turn off the receiver first. Remove the screw on the battery cover of the receiver and then remove the battery cover. Replace the old battery with a new one of the same type, making sure that the polarity connections are correct. Reinstall the battery cover and the screw.
REPLACING THE FUSE IN THE TRANSMITTER
The fuse in the transmitter protects the transmitter against overload or faulty manipulation.
If the output signal generated by the transmitter is weak and can be increased to a normal level, the fuse in the transmitter may be damaged.
Use the following procedure to check whether the fuse is damaged:
- Disconnect the transmitter from all cables/leads connected.
- Turn on the transmitter, then set its transmission level to level 1. "1" is shown on the transmitter display. Connect one end of a test lead to the red terminal of the transmitter.
- Turn on the receiver. The receiver defaults to the automatic mode and the symbol "AUTO" appears on the receiver display as an indicator.
- Place both the transmitter and receiver on a wooden desk (or nonmetallic desk). Move the receiver probe close to the test lead that is connected to the red terminal of the transmitter, and adjust the position of the receiver until the receiver displays a reading which approximates 700. Do not move the receiver from now on in the following procedure, and note down this reading.
- Do not move the transmitter. Connect the unused end of the test lead to the black terminal of the transmitter.
- If the fuse in the transmitter is good, the reading on the receiver display will roughly double.
If needed, use the following steps to replace the fuse:
- Turn off the transmitter. Disconnect the transmitter from any cable/lead and circuit.
- Remove the screw on the battery cover of the transmitter, then remove the battery cover, and then remove the battery.
- Remove the screws on the back cover of the transmitter, and then remove the back cover. Replace the damaged fuse with a new one of the same ratings. Reinstall the back cover and its screws. Then reinstall the battery, the battery cover, and the screw correctly.
The transmitter uses one fuse whose ratings are: 500mA/600V, F action, ∅6.35X32mm.
INSTRUMENT CALIBRATION
To ensure measurement accuracy, the instrument must be periodically calibrated by our company. The recommended calibration interval is one year.
If the instrument is used very often or if it is used under rough conditions, we recommend shorter intervals. If the instrument is used only a few times, the calibration interval can be extended to 3 years.
TRANSPORT AND STORAGE
Please keep the original packaging for later transport, e.g. for calibration. Any transport damage due to faulty packaging will be excluded from warranty claims.
In order to avoid damage caused by battery leakage, remove batteries from the instrument if you do not use the instrument for a period of time.
When the instrument is not in use, it must be stored in a dry area without intense electromagnetic fields.
