2. Maklumat Keselamatan

Amaran: To avoid electrical shock or personal injury, read all safety information before using this product. Use the product only as specified in this manual, or the protection provided by the product may be impaired.

• Sentiasa pastikan meter berada dalam fungsi dan julat yang betul sebelum membuat pengukuran.
• Jangan gunakan lebih daripada vol yang dinilaitage, seperti yang ditandakan pada meter, antara terminal atau antara mana-mana terminal dan tanah bumi.
• Berhati-hati apabila bekerja dengan voltagadalah melebihi 30V AC RMS, puncak 42V atau 60V DC. Ini voltagia menimbulkan bahaya kejutan.
• Sebelum mengukur arus, pastikan litar dinyahdayakan dan litaramp jaws are properly closed around the conductor.
• Do not operate the meter with the battery cover open.
• Gantikan bateri dengan segera apabila penunjuk bateri rendah muncul.
• Always disconnect test leads from the circuit before changing functions.
• Adhere to all local and national safety codes.

5. Persediaan

5.1 Pemasangan Bateri

1. Pastikan meter dimatikan.
2. Cari penutup petak bateri di belakang meter.
3. Gunakan pemutar skru untuk melonggarkan skru yang menahan penutup bateri.
4. Tanggalkan penutup bateri.
5. Insert three AAA 1.5V batteries, observing the correct polarity (+ and -).
6. Pasang semula penutup bateri dan ketatkan skru.

5.2 Menghubungkan Petunjuk Ujian

Untuk voltage, resistance, capacitance, frequency, duty cycle, diode, and continuity measurements:

• Insert the red test lead into the "INPUT" terminal.
• Insert the black test lead into the "COM" (common) terminal.

6. Arahan Operasi

6.1 Hidupkan/Mati Kuasa

Rotate the function dial from the "OFF" position to any desired measurement function to turn the meter ON. To turn OFF, rotate the dial back to the "OFF" position.

6.2 Pemilihan Fungsi

The large rotary dial allows selection of various measurement functions. Some positions on the dial may have multiple functions (e.g., AC voltage dan DC voltage). Tekan ke "SEL" button to cycle through these functions.

6.3 Pengukuran Arus AC/DC (Clamp)

1. Rotate the function dial to the "A~" (Arus AC) atau "A=" kedudukan (Arus DC).
2. Tekan clamp trigger to open the jaws.
3. Enclose a single conductor (not a power cord with multiple wires) within the clamp rahang. Pastikan rahang ditutup sepenuhnya.
4. Baca nilai semasa pada LCD.
5. For DC current, observe the polarity indicated on the display.

6.4 AC/DC Jldtage Pengukuran

1. Connect the red test lead to the "INPUT" terminal and the black test lead to the "COM" terminal.
2. Rotate the function dial to the "V~" (Jilid ACtage) atau "V=" (DC Voltage) kedudukan. Gunakan "SEL" butang jika perlu.
3. Sambungkan wayar ujian secara selari dengan litar atau komponen yang diuji.
4. Baca voltagnilai e pada LCD.

6.5 Resistance, Capacitance, Frequency, Duty Cycle, Diode, and Continuity

For these measurements, connect the test leads as described in Section 5.2. Rotate the function dial to the appropriate position and use the "SEL" button to select the specific function if multiple are available on one dial position.

• Rintangan (Ω): Pastikan litar dinyahtenagakan sebelum mengukur rintangan.
• Kapasitansi (F): Discharge capacitors before measurement.
• Kekerapan (Hz) / Duty Cycle (%): Connect across the signal source.
• Ujian Diod (→|): Connect the red lead to the anode and black lead to the cathode.
• Ujian Kesinambungan ()))): A built-in buzzer will sound if the resistance is below approximately 50Ω.

6.6 Fungsi Khas

• "HOLD" Button: Press to freeze the current reading on the display. Press again to release.
• "MAX/MIN" Button: Press to enter MAX/MIN recording mode. The meter will display the maximum or minimum value measured since entering the mode. Press again to cycle between MAX, MIN, and current reading. Hold to exit.
• "REL" (Relative) Button: Press to store the current reading as a reference value. Subsequent measurements will be displayed as the difference from this reference. Press again to exit.
• Backlight/Clamp Cahaya: The backlight and clamp light can be activated for improved visibility in low-light conditions. Refer to the specific button on the meter (often combined with another function or a dedicated light button).

7. Penyelenggaraan

7.1 Pembersihan

Lap kes dengan iklanamp kain dan detergen lembut. Jangan gunakan bahan pelelas atau pelarut. Pastikan terminal bebas daripada kotoran dan kelembapan.

7.2 Penggantian Bateri
