5. Opsætning
5.1 Batteriinstallation
The Transmitter requires one 9V (IEC 6LR61) battery, and the Receiver requires six 1.5V AAA (IEC LRO3) batteries. Batteries are not included.
- Find batterirummet på bagsiden af både sender- og modtagerenhederne.
- Åbn batterirummets dæksel.
- Indsæt batterierne, og sørg for korrekt polaritet (+/-).
- Luk batterirummets dæksel forsvarligt.
5.2 Tilslutning af testledninger
For most applications, connect the red and black test leads to the corresponding input jacks on the Transmitter. The other ends of the test leads will be connected to the circuit or cable you wish to trace.


6. Betjeningsvejledning
6.1 General Cable Tracing
- Connect the Transmitter to the cable or circuit you want to trace. Ensure a good electrical connection. For non-energized cables, you may need to connect one lead to the cable and the other to a ground rod.
- Tænd for både senderen og modtageren.
- On the Transmitter, select the desired transmit power level and code using the 'LEVEL SEL' and 'CODE SEL' buttons. Press 'START/STOP' to begin transmission.
- On the Receiver, adjust the sensitivity ('LEVEL' buttons) as needed.
- Move the Receiver along the suspected path of the cable. The signal strength displayed on the LCD and the audible tone will increase as you get closer to the cable.
- Follow the strongest signal to accurately trace the cable's path.


6.2 bindtage Measurement (Transmitter)
The Transmitter can measure AC and DC voltages direkte.
- Connect the test leads from the Transmitter to the voltage kilde.
- The Transmitter's LCD will automatically display the measured voltage value and indicate whether it is AC or DC. A high-voltage flash warning symbol will appear if applicable.
6.3 Fuse and Circuit Finding
- Connect the Transmitter to the circuit where the fuse is located.
- Use the Receiver to scan the fuse box. The strongest signal will indicate the correct fuse.


6.4 Brug af lommelygten
Both the Transmitter and Receiver are equipped with a flashlight function. Press the dedicated flashlight button (often indicated by a light bulb icon) to activate it, useful for working in dark areas.

7. Vedligeholdelse
- Rensning: Tør enheden af med en tør, blød klud. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Opbevaring: Store the device in its storage bag in a cool, dry place when not in use. Remove batteries if storing for extended periods to prevent leakage.
- Udskiftning af batteri: Udskift batterierne med det samme, når indikatoren for lavt batteriniveau vises på LCD-skærmen.
- Inspektion: Periodically inspect test leads and connectors for any signs of wear or damage. Replace if necessary.
8. Fejlfinding
8.1 Intet signal eller svagt signal
- Tjek batterier: Ensure both the Transmitter and Receiver have sufficient battery power. Replace if low.
- Forbindelse: Verify that the test leads are securely connected to the Transmitter and the circuit/cable.
- Senderstatus: Check the Transmitter's LCD for its emission status and any error messages.
- Modtager følsomhed: Adjust the Receiver's sensitivity level. Increase it for deeper or weaker signals.
- Interferens: Strong electromagnetic fields from other devices can interfere with the signal. Try to minimize such interference.
- Afstand: Ensure the Receiver is within the effective tracking range of the Transmitter.
8.2 Unøjagtige aflæsninger
- Kalibrering: While the device has an auto-sweep function, ensure you are following the operating instructions for your specific task.

10. Brugertips
- For optimal tracing results, ensure the circuit is de-energized if possible, or use the lowest possible signal level on the transmitter to avoid signal bleed to adjacent lines.
- When tracing deeply buried cables, try to maintain a consistent distance and angle with the receiver for more accurate readings.
- Always check the battery levels before starting a task to avoid interruptions.
