2. Maklumat Keselamatan

Untuk memastikan operasi yang selamat, patuhi langkah berjaga-jaga keselamatan berikut:

• Sentiasa mematuhi kod keselamatan tempatan dan nasional.
• Jangan gunakan meter jika ia kelihatan rosak atau jika penebat pada wayar ujian terjejas.
• Verify the meter's operation on a known voltage source before use.
• Jangan gunakan lebih daripada vol yang dinilaitage, seperti yang ditanda pada meter, antara terminal atau antara mana-mana terminal dan bumi.
• Berhati-hati apabila bekerja dengan voltagadalah melebihi 30V AC RMS, puncak 42V atau 60V DC. Ini voltagia menimbulkan bahaya kejutan.
• Simpan jari di belakang pelindung jari pada probe ujian semasa pengukuran.
• Putuskan sambungan wayar ujian daripada litar sebelum menukar fungsi.
• Tanggalkan kabel ujian daripada meter sebelum membuka penutup bateri.
• Gantikan bateri dengan segera apabila penunjuk bateri rendah muncul.
• Jangan kendalikan meter dalam persekitaran gas meletup, wap atau habuk.

4.1 Pemasangan Bateri

The Thsinde 38B+ Digital AC Clamp Multimeter requires three AAA batteries for operation.

1. Ensure the meter is powered off and disconnect all test leads.
2. Locate the battery door on the back of the meter.
3. Use a screwdriver to loosen the battery door screw.
4. Keluarkan pintu bateri.
5. Masukkan tiga bateri AAA, dengan memerhatikan kekutuban yang betul (+ dan -) seperti yang ditunjukkan di dalam petak.
6. Gantikan pintu bateri dan ketatkan skru dengan selamat.

4.2 Menghubungkan Petunjuk Ujian

Untuk ukuran yang memerlukan petunjuk ujian (cth, voltage, resistance, continuity), connect them as follows:

• Insert the black test lead into the COM (common) input jack.
• Insert the red test lead into the positive input jack (+).
• Pastikan sambungan kukuh sebelum mengambil sebarang ukuran.

5. Arahan Operasi

This section details how to use the various measurement functions of your multimeter.

5.1 Hidupkan/Mati Kuasa

• To power on the meter, rotate the Function Select Switch from the "OFF" position to any desired measurement function.
• The meter features an "AUTO POWER OFF" function to conserve battery life. It will automatically shut down after a period of inactivity.
• To power off the meter, rotate the Function Select Switch to the "OFF" position.

5.2 Pengukuran Arus AC/DC (Clamp Fungsi)

Gunakan clamp jaws for non-contact current measurement.

1. Rotate the Function Select Switch to the "~ 200/600A" or "~ 2/20A" range for AC current, or "mA" or "µA" for DC current (if available via clamp, otherwise use leads for DC mA/µA).
2. Tekan picu untuk membuka clamp rahang.
3. Encircle a single conductor with the clamp jaws. Ensure the jaws are fully closed around the conductor.
4. Baca nilai semasa pada paparan.
5. For DC current, observe the polarity indicated on the display.

5.3 AC/DC Jldtage Pengukuran

1. Connect the black test lead to the COM jack and the red test lead to the positive (+) jack.
2. Rotate the Function Select Switch to the "V" position. The meter will typically auto-range between AC and DC voltage. Use the "SEL" button if manual selection is needed.
3. Sambungkan prob ujian secara selari dengan litar atau komponen yang ingin anda ukur.
4. Baca voltagnilai e pada paparan.

5.4 Pengukuran Rintangan

1. Pastikan litar dinyahtenagakan sebelum mengukur rintangan.
2. Connect the black test lead to the COM jack and the red test lead to the positive (+) jack.
3. Rotate the Function Select Switch to the "Ω" (Ohms) position.
4. Connect the test probes across the component or circuit where resistance is to be measured.
5. Baca nilai rintangan pada paparan.

5.5 Ujian Kesinambungan

1. Pastikan litar dinyahdayakan sebelum menjalankan ujian kesinambungan.
2. Connect the black test lead to the COM jack and the red test lead to the positive (+) jack.
3. Rotate the Function Select Switch to the "Ω" position and press "SEL" until the continuity symbol (speaker icon) appears.
4. Touch the test probes to the two points of the circuit you want to test.
5. Jika kesinambungan wujud (rintangan di bawah ambang tertentu), meter akan mengeluarkan bunyi bip yang boleh didengar.

5.6 Bukan Kenalan Voltage (NCV) Pengesanan

1. Rotate the Function Select Switch to the "NCV" position.
2. Move the top part of the meter (near the clamp jaws) close to the conductor or outlet you want to test for AC voltage.
3. The NCV indicator LED will light up and an audible beep will sound, with increasing frequency as the meter gets closer to the voltage sumber.

5.7 Other Functions (Diode, Capacitance, Frequency)

To access Diode, Capacitance, or Frequency measurements, rotate the Function Select Switch to the appropriate symbol (e.g., "Diode/Capacitance" or "Hz/%") and use the "SEL" button to cycle through the available functions. Follow standard procedures for connecting test leads and taking readings for each specific function.

6. Penyelenggaraan

6.1 Pembersihan

• Lap bekas meter dengan iklanamp cloth and a mild detergent. Do not use abrasives or solvents.
• Pastikan terminal input bebas daripada kotoran dan lembapan.

6.2 Penggantian Bateri

Apabila penunjuk bateri rendah muncul pada paparan, gantikan bateri seperti yang diterangkan dalam Bahagian 4.1.

6.3 Penyimpanan

• If the meter is not used for an extended period, remove the batteries to prevent leakage.
• Simpan meter di tempat yang sejuk dan kering, jauh daripada cahaya matahari langsung dan suhu yang melampau.
• Utilize the provided storage bag for protection.
