4. Arahan Operasi

The ANENG SZ308 features a user-friendly rotary dial for selecting various measurement functions.

Figure 4.1: The function dial allows selection of different measurement modes.

4.1 AC/DC Jldtage Pengukuran

Rajah 4.2: Mengukur AC voltage at an electrical outlet using the multimeter.

1. Turn the function dial to the desired AC Voltage (V~) atau Voltan DCtage (V=) range.
2. Connect the black test lead to the COM jack and the red test lead to the VΩmA jack.
3. Sentuh kuar ujian ke titik di mana anda ingin mengukur voltage.
4. Baca voltagnilai e pada skrin LCD.

4.2 Pengukuran Arus DC

The ANENG SZ308 can measure DC current in various ranges.

1. Turn the function dial to the desired DC Current (A=) range (e.g., 200m, 10A).
2. For currents up to 200mA, connect the black test lead to COM and the red test lead to VΩmA.
3. For currents up to 10A, connect the black test lead to COM and the red test lead to the 10A jack.
4. Open the circuit where you want to measure current and connect the multimeter in series.
5. Baca nilai semasa pada skrin LCD.

4.3 Pengukuran Rintangan

1. Turn the function dial to the Resistance (Ω) range.
2. Connect the black test lead to COM and the red test lead to VΩmA.
3. Pastikan litar dinyahtenagakan sebelum mengukur rintangan.
4. Touch the test probes across the component or circuit you wish to measure.
5. Baca nilai rintangan pada skrin LCD.

4.4 Ujian Kesinambungan

1. Turn the function dial to the Continuity (buzzer icon) range.
2. Connect the black test lead to COM and the red test lead to VΩmA.
3. Pastikan litar dinyahtenagakan.

Lap multimeter casing dengan iklanamp kain dan detergen lembut. Jangan gunakan bahan pelelas atau pelarut. Pastikan peranti benar-benar kering sebelum digunakan.

5.3 Penggantian Fius

The ANENG SZ308 is equipped with internal fuses for overload protection. If the multimeter fails to measure current, the fuse may need replacement. Refer to the internal diagram or contact customer support for guidance on fuse specifications and replacement procedures. Always replace with a fuse of the same type and rating.

6. Penyelesaian masalah

• Tiada paparan atau paparan samar: Check battery installation. Replace the 9V battery if low battery indicator is on or if the display is dim.
• No reading in current mode: Check if the test leads are connected to the correct current jacks (VΩmA or 10A) and if the fuse is intact.
• "OL" (Beban Lebihan) dipaparkan: The measured value exceeds the selected range. Select a higher range or ensure the circuit is within the multimeter's capabilities.
• Bacaan tidak tepat: Ensure the battery is not low, test leads are properly connected, and the correct function is selected. Avoid strong electromagnetic interference.
