5. Persediaan

5.1 Pemasangan Bateri

The LSG-4 is battery-powered. Open the battery compartment on the back of the DMM unit and the probe unit. Insert the required batteries, ensuring correct polarity. Close the compartment securely.

5.2 Connecting Test Leads (for Multimeter Functions)

For multimeter measurements, insert the red test lead into the VΩmA jack and the black test lead into the COM jack on the DMM unit.

5.3 Connecting Tone Generator (for Wire Tracking)

To use the wire tracking function, connect the tone generator output from the DMM unit to the cable you wish to trace:

• Sambungan RJ11: Plug the RJ11 cable into the dedicated RJ11 port on the DMM unit and the other end into the network or telephone jack of the cable to be traced.
• Klip Buaya: Attach the crocodile clips to the tone generator output on the DMM unit, then securely clip them to the bare ends of the wire to be traced.

6. Arahan Operasi

6.1 Wire Tracking and Signal Tracing

1. Connect the tone generator to the cable as described in Section 5.3.
2. Turn on the DMM unit and select the 'Tone' function.
3. Turn on the LSG-4 probe.
4. Adjust the sensitivity of the probe using its control dial to optimize signal detection.
5. Move the tip of the probe along the suspected path of the cable. The probe will emit an audible tone when it detects the signal from the tone generator.
6. Follow the strongest signal to accurately trace the cable's route.

6.2 Fungsi Multimeter

The LSG-4 offers standard multimeter functions. To use these:

1. Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 5.2.
2. Turn on the DMM unit and select the desired measurement function (e.g., V_AC, V_DC, Ω, Cont).
3. Touch the test probes to the circuit or component you wish to measure.
4. Baca nilai ukuran pada paparan.
5. Use the 'Hold' button to freeze the current reading on the display.
6. The 'MAX' button can be used to capture the maximum measured value.

7. Penyelenggaraan

• Pembersihan: Bersihkan peranti dengan kain lembut dan kering. Jangan gunakan pembersih atau pelarut yang melelas.
• Penggantian Bateri: Replace batteries when the low battery indicator appears on the display to ensure accurate measurements.
• Storan: Simpan peranti di tempat yang sejuk dan kering, jauh daripada cahaya matahari langsung dan suhu yang melampau. Tanggalkan bateri jika disimpan untuk tempoh yang lama.
• Penentukuran: Regular calibration by qualified personnel is recommended to maintain measurement accuracy.

8. Penyelesaian masalah

• Tiada Paparan/Kuasa: Periksa pemasangan bateri dan pastikan bateri dicas.
• Bacaan Tidak Tepat: Ensure test leads are properly connected and the correct function/range is selected. Replace batteries if low.
• Weak/No Signal during Tracing: Ensure the tone generator is connected correctly and active. Adjust probe sensitivity. Check for excessive interference from other electrical sources.
• Continuity Test Fails: Pastikan litar dinyahtenagakan. Periksa petunjuk ujian untuk kerosakan.
