Oddajnik: Connects to the wire to be traced. Features a Power indicator, Cable Scan/OFF/Battery Test switch, Status indicator, and Alligator Clips & leads.
Sprejemnik: Used to detect the signal from the transmitter. Features a Lighting LED, Headphone interface, Signal Sensitivity Adjusting Switch, On/Off Switch, and a flexible Probe with a T-shaped coil.

4. Nastavitev

4.1 Polnjenje baterij

Both the Transmitter and Receiver are equipped with rechargeable lithium-ion batteries. Use the provided charging cable to charge both units before first use and whenever the battery is low. The Power indicator LED will show charging status.

4.2 Priključitev oddajnika

To trace a wire, connect the transmitter to the wire using the alligator clips. Ensure a secure connection.

Connect the red alligator clip to the wire you wish to trace.
Connect the black alligator clip to a reliable ground source. For underground wires, this typically means a metal stake driven into the earth.
Ensure the wire is not live and has no voltage exceeding 60V DC.

5.1 Powering On and Function Selection

Oddajnik: Slide the "Cable Scan" switch to the "Cable Scan" position to activate the tracing signal. The Power indicator will light up.
Sprejemnik: Slide the On/Off switch to the "ON" position. The Power indicator will light up.

5.2 Sledenje žic

To locate and trace wires:

Ensure the transmitter is connected and powered on in "Cable Scan" mode.
Turn on the receiver. Adjust the "Signal Sensitivity Adjusting Switch" on the receiver to an appropriate level. Start with a lower sensitivity and increase as needed.
Hold the receiver with the T-shaped probe near the suspected path of the wire.
Move the probe slowly across the area. The receiver will emit a sound, and the signal strength will be indicated.
The sound will be loudest when the probe is directly above the cable and at a 90-degree angle to it. This indicates the target cable is perpendicular to the probe.
When the probe is parallel to the cable direction, the signal will be weakest or absent.

The detection range is typically up to 2-3 feet deep and 1000 feet long, though depth can vary based on soil conditions and wire type (e.g., 1-2 feet in steel/iron/PVC pipes).

5.3 Cable Break Detection

To detect a cable break, follow the wire tracing procedure. The signal will significantly weaken or disappear at the point of the break.

5.4 Short Testing

To test for short circuits:

Clamp the alligator clips of the transmitter to the exposed parts of the two wires you want to test.
Slide the transmitter switch to the "Battery Test" position.
Observe the "Status" indicator LED on the transmitter:
- If the "Status" LED is vedno svetlo, it indicates a short circuit.
- If the "Status" LED is ni svetla, it means there is no short circuit.

5.5 Battery Polarity Test (9-60V)

The transmitter can also test battery polarity:

Connect the red and black alligator clips to the positive and negative terminals of a 9-60V battery, respectively.
Slide the transmitter switch to the "Battery Test" position.
Observe the "Status" indicator LED:
- If the "Status" LED is ni svetla, it means the red clip side is the positive terminal.
- If the "Status" LED is svetlo, it means the red clip side is the negative terminal.

5.6 Uporaba LED svetilke

The receiver has a built-in LED flashlight for use in dark or low-light conditions. Press the "Push for Light" button on the receiver to turn the LED on or off.

5.7 Noise Reduction with Headphones

For noisy environments, you can plug headphones into the receiver's headphone interface to better distinguish the tracing sound. This helps in isolating the signal from ambient noise.

Skrb za sondo: Ensure the T-shaped probe is clean and free from debris for optimal performance.

7. Odpravljanje težav

Težava	Možen vzrok	rešitev
No signal or weak signal from receiver.	Transmitter not powered on or low battery. Receiver not powered on or low battery. Incorrect connection to the wire or poor ground. Wire is too deep or too far. Receiver sensitivity set too low. Wire is multi-stranded or live (device not suitable).	Check power and battery levels of both units. Ensure secure connection of alligator clips and a good ground. Increase receiver sensitivity. Verify the wire type is single-stranded or parallel double-stranded and not live.
Inaccurate wire location.	High interference from other electrical sources. Probe not held correctly (perpendicular to wire). Multiple cables in close proximity.	Try to minimize interference sources. Ensure the probe is held perpendicular to the suspected wire path for strongest signal. Adjust sensitivity carefully and move slowly to pinpoint the signal.
Transmitter "Status" LED not responding during short test.	Transmitter not in "Battery Test" mode. Poor connection to wires.	Ensure the switch is set to "Battery Test". Check alligator clip connections for secure contact.
