3. Persediaan

3.1. Pemasangan Bateri

1. Pastikan multimeter dimatikan dan semua kabel ujian diputuskan sambungannya.
2. Locate the battery compartment cover on the back of the meter (refer to Figure 1).
3. Tanggalkan skru penahan dan tanggalkan penutup dengan berhati-hati.
4. Insert a new 9V battery (NEDA 1604 or 6F22 type), observing the correct polarity (+ and -).
5. Gantikan penutup petak bateri dan kencangkannya dengan skru.

3.2. Menghubungkan Petunjuk Ujian

• Sambungkan merah test lead to the "VΩmA" input jack.
• Sambungkan hitam test lead to the "COM" (common) input jack.
• For current measurements exceeding 200mA (up to 10A), connect the red test lead to the "10A" input jack.

4. Arahan Operasi

4.1. Pemilihan Fungsi

Turn the rotary switch to the desired measurement function and range. Always start with a higher range if the approximate value is unknown to prevent overloading the meter.

4.2. Mengukur DC Voltage (V–)

1. Tetapkan suis putar kepada Vol DC yang dikehendakitage (V–) range (e.g., 20V, 200V).
2. Sambungkan petunjuk ujian merah ke sisi positif (+) litar dan petunjuk ujian hitam ke sisi negatif (-).
3. Baca voltagnilai e pada paparan LCD.

4.3. Mengukur Vol ACtage (V∼)

1. Tetapkan suis putar kepada Vol AC yang dikehendakitage (V∼) range (e.g., 200V, 750V).
2. Sambungkan petunjuk ujian merentasi vol ACtage sumber.
3. Baca voltagnilai e pada paparan LCD.

4.4. Measuring DC Current (A–)

Awas: To measure current, the meter must be connected in series with the circuit. Never connect the meter in parallel with a voltage source when in current mode, as this can damage the meter and the circuit.

1. Set the rotary switch to the desired DC Current (A–) range (e.g., 20mA, 200mA, 10A).
2. For currents up to 200mA, ensure the red lead is in the "VΩmA" jack. For currents up to 10A, move the red lead to the "10A" jack.
3. Buka litar di mana arus akan diukur dan sambungkan meter secara bersiri.
4. Baca nilai semasa pada paparan LCD.

4.5. Mengukur Rintangan (Ω)

Awas: Pastikan litar atau komponen yang diuji dinyahtenagakan sebelum mengukur rintangan.

1. Set the rotary switch to the desired Resistance (Ω) range (e.g., 200Ω, 2kΩ, 200kΩ).
2. Sambungkan wayar ujian merentasi komponen atau litar yang hendak diukur.
3. Baca nilai rintangan pada paparan LCD.

4.6. Diode Test (→|–)

1. Set the rotary switch to the Diode Test (→|–) position.
2. Sambungkan wayar ujian merah ke anod diod dan wayar ujian hitam ke katod.
3. Paparan akan menunjukkan vol ke hadapantage drop (biasanya 0.5V hingga 0.8V untuk diod silikon).
4. Balikkan petunjuk. Paparan harus menunjukkan "OL" (Gelung Terbuka) untuk diod yang baik.

4.7. Transistor (hFE) Test

1. Tetapkan suis putar ke kedudukan hFE.
2. Kenal pasti sama ada transistor tersebut adalah NPN atau PNP.
3. Insert the transistor's emitter, base, and collector leads into the corresponding sockets on the hFE test socket.
4. Read the hFE (DC current gain) value on the display.

5. Penyelenggaraan

5.1. Penggantian Bateri

When the low battery indicator appears on the display, replace the 9V battery as described in Section 3.1. Using a low battery can lead to inaccurate readings.

5.2. Penggantian fius

If the current measurement function stops working, the fuse may need replacement. This operation should only be performed by qualified personnel.

1. Pastikan multimeter dimatikan dan semua kabel ujian diputuskan sambungannya.
2. Open the back casing of the meter (this may involve more screws than just the battery compartment).
3. Locate the blown fuse and replace it with a fuse of the exact same type and rating (e.g., F200mA/250V for mA range, F10A/250V for 10A range). Refer to the internal markings or specifications for precise fuse ratings.
4. Carefully reassemble the meter, ensuring all screws are tightened.

5.3. Pembersihan

Lap meter dengan iklanamp kain dan detergen ringan. Jangan gunakan bahan kasar atau pelarut. Pastikan meter kering.
