4. Pasang kembali penutup dan kencangkan dengan sekrup.

4.2 Menghubungkan Kabel Uji

Hubungkan kabel uji ke jack input yang sesuai pada multimeter:

• Masukkan kabel tes hitam ke dalam DAPAT (Jack) umum.
• Masukkan kabel tes merah ke dalam VΩmA jack untuk voltage, resistansi, dan pengukuran arus rendah.
• Untuk pengukuran arus tinggi (hingga 10A), masukkan kabel uji merah ke dalam 10A MAX FUSED mendongkrak.

5. Petunjuk Pengoperasian

The rotary dial on the front of the multimeter is used to select the desired measurement function and range.

5.1 Operasi Umum

1. Turn the rotary dial to the desired function (e.g., V for voltage, Ω for resistance, A for current).
2. Connect the test probes to the circuit or component being tested.
3. Read the measurement on the large LCD display. The multimeter features automatic reverse polarity indication.
4. Tekan tombol MEMEGANG Tekan tombol untuk membekukan pembacaan saat ini pada layar. Tekan lagi untuk melepaskan.

5.2 Automotive Specific Functions

Tachometer (RPM) Measurement:

• Putar tombol putar ke RPMx10 pengaturan.
• Select the appropriate cylinder setting (4CYL, 6CYL, 8CYL) for the engine being tested.
• Connect the red test lead to the negative terminal of the ignition coil or the tachometer test point, and the black lead to a good ground.
• Start the engine and read the RPM value on the display. Multiply the reading by 10 for the actual RPM.

Dwell Measurement:

• Putar tombol putar ke TINGGAL pengaturan.
• Select the appropriate cylinder setting (4CYL, 6CYL, 8CYL) for the engine being tested.
• Connect the red test lead to the negative terminal of the ignition coil or the dwell test point, and the black lead to a good ground.
• Start the engine and read the dwell angle on the display.

Jil.tage Testing (Starting, Charging, Fuel Delivery Systems):

• Select the appropriate DC Voltage (V–) range.
• Connect the red test lead to the positive point of the circuit (e.g., battery positive terminal, alternator output) and the black test lead to a good ground.
• Baca vol.tage pada layar.

Diode Function:

• Turn the rotary dial to the diode symbol (→|–).
• Hubungkan kabel uji merah ke anoda dan kabel uji hitam ke katoda dioda.
• Sebuah volume majutage drop will be displayed for a good diode. Reverse the leads; an open circuit (OL) should be displayed.

6. Pemeliharaan

6.1 Penggantian Sekring

The multimeter is protected by a fuse. If the current measurement function stops working, the fuse may need replacement.

• The multimeter uses a F0.5AL250V 5X20mm fuse.
• To replace the fuse, open the battery compartment cover as described in Section 4.1.
• Carefully remove the old fuse and insert a new fuse of the correct type and rating.
• Pasang kembali penutup dan kencangkan dengan sekrup.

6.2 Pembersihan

Bersihkan multimeter casing dengan iklanamp kain. Jangan gunakan pembersih atau pelarut yang bersifat abrasif.

7. Penyelesaian masalah

• Tidak ada tampilan atau tampilan redup: Periksa pemasangan dan pengisian daya baterai. Ganti baterai jika perlu.
• Pembacaan yang salah: Ensure test leads are properly connected and the correct function/range is selected. Verify the component being tested is functioning correctly.
• Pengukuran arus tidak berfungsi: Check and replace the fuse (refer to Section 6.1).
• RPM/Dwell readings inconsistent or zero: Ensure proper connection to the ignition system and correct cylinder setting. Verify engine is running smoothly.
