MustOOL MT336 Digital Clamp Manual Pengguna Meter

1. Pengenalan

The MustOOL MT336 is a versatile 2-in-1 True RMS Digital Clamp Meter and Oscilloscope. This device allows for non-contact measurement of AC current waveforms, DC/AC voltage, resistance, capacitance, frequency, and temperature. It features a waveform display for quick analysis and includes functions like diode testing and continuity checks. Designed for safety and efficiency, it is an essential tool for electrical measurements.

2. Maklumat Keselamatan

Sentiasa patuhi langkah berjaga-jaga keselamatan apabila menggunakan peralatan ujian elektrik. Kegagalan berbuat demikian boleh mengakibatkan renjatan elektrik, kecederaan, atau kerosakan pada meter atau peralatan yang sedang diuji.

• Jangan melebihi had input maksimum untuk sebarang fungsi.
• Ensure the test leads are in good condition and properly connected before use.
• Do not use the meter if it appears damaged or if the battery cover is not properly closed.
• Berhati-hati apabila bekerja dengan voltagadalah melebihi 60V DC atau 30V AC RMS.
• Sentiasa putuskan sambungan kuasa ke litar sebelum membuat ukuran rintangan, kemuatan atau diod.
• Remove test leads from the meter before opening the battery compartment.

4. Persediaan

4.1 Pemasangan Bateri

1. Ensure the meter is powered off and no test leads are connected.
2. Cari petak bateri di belakang meter.
3. Tanggalkan penutup petak bateri.
4. Insert three AAA 1.5V batteries, observing correct polarity.
5. Gantikan penutup petak bateri dan kencangkannya dengan skru.

4.2 Menghubungkan Petunjuk Ujian

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

• Masukkan petunjuk ujian hitam ke dalam COM (Bicu input biasa).
• Masukkan petunjuk ujian merah ke dalam VΩHz bicu input.

For temperature measurements, connect the temperature probe to the designated input ports.

5. Arahan Operasi

5.1 Hidupkan/Mati Kuasa

Press the power button to turn the meter on. The meter will automatically shut down after 15 minutes of inactivity to conserve battery life. Press the power button again to turn it off manually.

5.2 Pengukuran Arus AC (Clamp Fungsi)

1. Select the AC current mode (usually indicated by 'A~' or a similar symbol).
2. Tekan picu untuk membuka clamp Rahang.
3. Enclose a single conductor (not a power cord with multiple wires) within the clamp Rahang.
4. Lepaskan picu untuk menutup rahang dengan selamat di sekeliling konduktor.
5. Read the AC current value and waveform on the display.

5.3 AC/DC Jldtage Pengukuran

1. Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 4.2.
2. Pilih vol yang sesuaitage mode (DCV or ACV).
3. Touch the red and black test probes to the points where voltage perlu diukur.
4. Baca voltagnilai e pada paparan. Untuk volum ACtage, the waveform may also be displayed.

5.4 Resistance, Capacitance, Frequency, Diode, and Continuity

For these functions, ensure the circuit is de-energized before connecting the test leads. Select the desired function using the mode buttons and follow standard measurement procedures for multimeters.

• Rintangan (Ω): Measures the electrical resistance of a component.
• Kapasitansi (F): Measures the capacitance of capacitors.
• Kekerapan (Hz): Measures the frequency of an AC signal.
• Ujian Diod: Memeriksa volum hadapantage drop of a diode.
• Ujian Kesinambungan: Indicates if a circuit is complete with a low resistance path (typically with an audible beep).

5.5 Pengukuran Suhu

Connect the temperature probe to the meter's designated input. Select the temperature function and place the probe tip on the object or area to be measured. The temperature will be displayed in Celsius or Fahrenheit.

6. Penyelenggaraan

6.1 Pembersihan

Wipe the meter with a dry, soft cloth. Do not use abrasives or solvents. Keep the input terminals free of dirt and moisture.

6.2 Penggantian Bateri

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Use three new AAA 1.5V batteries.

6.3 Penyimpanan

Jika meter tidak digunakan untuk tempoh yang lama, tanggalkan bateri untuk mengelakkan kebocoran dan kerosakan. Simpan meter di tempat yang sejuk dan kering, jauh daripada cahaya matahari langsung.
