• Suis Fungsi: Rotary dial to select measurement modes (Voltage, Arus, Rintangan, dsb.).
• Butang TAHAN: Membekukan bacaan semasa pada paparan.
• Bicu Input: Terminals for connecting test leads (COM, VΩmA, 10A).

4. Persediaan

4.1 Pemasangan Bateri

The Ingco DM2002 requires alkaline batteries for operation. Ensure the correct polarity when inserting batteries.

1. Cari petak bateri di belakang multimeter.
2. Gunakan pemutar skru untuk membuka penutup petak bateri.
3. Insert the required alkaline batteries, observing the polarity markings (+ and -).
4. Gantikan penutup petak bateri dan kencangkannya dengan skru.

4.2 Menghubungkan Petunjuk Ujian

Sambungan wayar ujian yang betul adalah penting untuk pengukuran yang tepat dan selamat.

• Masukkan petunjuk ujian hitam ke dalam bicu input 'COM' (Umum).
• Untuk kebanyakan ukuran (voltage, resistance, capacitance, frequency, temperature, and small currents), insert the red test lead into the 'VΩmA' input jack.
• For measuring large currents (up to 10A), insert the red test lead into the '10A' input jack. Ensure the function switch is set to the appropriate current range.

5. Arahan Operasi

Before taking any measurement, ensure the test leads are correctly connected and the function switch is set to the desired measurement mode.

5.1 Mengukur Vol. AC/DCtage (V~ / V-)

1. Connect the black test lead to 'COM' and the red test lead to 'VΩmA'.
2. Set the function switch to the desired AC Voltage (V~) atau Voltan DCtagjulat e (V-).
3. Sambungkan kuar ujian secara selari merentasi komponen atau litar yang hendak diukur.
4. Baca voltagnilai e pada paparan LCD.

5.2 Measuring AC/DC Current (A~ / A-)

Awas: Jangan sekali-kali menyambungkan multimeter secara selari dengan voltantage source when measuring current, as this can damage the meter and pose a safety risk.

1. Connect the black test lead to 'COM'.
2. For currents up to 200mA, connect the red test lead to 'VΩmA'. For currents up to 10A, connect the red test lead to '10A'.
3. Set the function switch to the desired AC Current (A~) or DC Current (A-) range.
4. Open the circuit where the current is to be measured and connect the multimeter in series with the circuit.
5. Baca nilai semasa pada paparan LCD.

5.3 Mengukur Rintangan (Ω)

1. Pastikan litar dinyahtenagakan sebelum mengukur rintangan.
2. Connect the black test lead to 'COM' and the red test lead to 'VΩmA'.
3. Set the function switch to the desired Resistance (Ω) range.
4. Sambungkan kuar ujian merentasi komponen yang hendak diukur.
5. Baca nilai rintangan pada paparan LCD.

5.4 Mengukur Kapasitansi (F)

1. Pastikan kapasitor dinyahcas sepenuhnya sebelum pengukuran untuk mengelakkan kerosakan pada meter.
2. Connect the black test lead to 'COM' and the red test lead to 'VΩmA'.
3. Set the function switch to the Capacitance (F) range.
4. Sambungkan kuar ujian merentasi terminal kapasitor.
5. Baca nilai kemuatan pada paparan LCD.

5.5 Measuring Frequency (Hz) and Temperature (°C/°F)

Refer to the specific markings on the rotary switch for Frequency (Hz) and Temperature (°C/°F) functions. The connection method for these measurements typically involves the 'COM' and 'VΩmA' jacks, often requiring a dedicated temperature probe for temperature measurements (not included with all multimeters).

5.6 Fungsi HOLD

Press the 'HOLD' button to freeze the current reading on the LCD display. Press it again to release the hold and resume live readings.

6. Penyelenggaraan

6.1 Pembersihan

Lap meter casing dengan iklanamp kain dan detergen lembut. Jangan gunakan bahan pelelas atau pelarut. Pastikan meter kering sebelum digunakan.

6.2 Penggantian Bateri

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Always use new alkaline batteries of the specified type.

6.3 Penggantian Fius

If the current measurement function stops working, the fuse may need replacement. This typically requires opening the meter's casing. Refer to the meter's internal markings for the correct fuse type and rating (e.g., 200mA/250V for mA range, 10A for 10A range). Only replace with a fuse of the identical type and rating.

6.4 Penyimpanan

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

7. Penyelesaian masalah

• Tiada Paparan / Paparan Samar: Check battery installation. Replace batteries if low battery indicator is present or if display is faint.
• Bacaan yang salah: Ensure the function switch is set to the correct range. Check test lead connections. Verify the circuit is properly connected.
• Pengukuran Semasa Tidak Berfungsi: Check the fuse. Replace if blown (refer to Section 6.3).
• 'OL' or '1' on Display: Indicates overload or out-of-range measurement. Select a higher range or verify circuit connection.
