3.2. Pemasangan Bateri
The multimeter requires batteries for operation. Locate the battery compartment on the rear of the device. Use a screwdriver to open the compartment cover, insert the batteries according to the polarity indicators, and then securely close the cover.
3.3. Menghubungkan Petunjuk Ujian
For most measurements, connect the black test lead to the "COM" (Common) input jack and the red test lead to the "VΩmA" input jack. For high current measurements (10A), connect the red test lead to the "10A" input jack.

4. Arahan Operasi
Before operating, ensure the multimeter is in good condition and the test leads are properly connected. Always select the appropriate function and range before making a measurement.
4.1. Hidupkan/Mati Kuasa
Rotate the rotary switch from the "OFF" position to any desired measurement function to power on the device. To power off, rotate the switch back to the "OFF" position. The device also features an automatic shut-down function after 15 minutes of inactivity.
4.2. AC/DC Voltage Pengukuran (V~)
- Set the rotary switch to the "V~" position for AC voltage atau "V-" untuk volum DCtage.
- Sambungkan wayar ujian secara selari dengan litar atau komponen yang diuji.
- Baca voltagnilai e pada paparan.
4.3. V.F.C. Variable Frequency Voltage Pengukuran
Semasa AC voltage measurement, press the "V.F.C." button to activate the variable frequency voltage measurement mode. This is useful for measuring voltage in circuits with variable frequency drives.
Figure 4.1: The multimeter's display showing V.F.C. mode activated for variable frequency voltage measurement. This function is engaged by pressing the "V.F.C." button during AC voltage pengukuran.
4.4. Pengukuran Rintangan (Ω)
- Tetapkan suis putar ke kedudukan "Ω".
- Pastikan litar dinyahtenagakan sebelum mengukur rintangan.
- Sambungkan petunjuk ujian merentasi komponen.
- Baca nilai rintangan pada paparan.
4.5. Capacitance Measurement (mF)
- Set the rotary switch to the "mF" position.
- Ensure the capacitor is fully discharged before measurement to prevent damage to the multimeter.
- Sambungkan petunjuk ujian merentasi terminal kapasitor.
- Baca nilai kapasitans pada paparan.
Figure 4.2: The multimeter displaying a capacitance measurement. The device supports up to 99.99mF capacitance measurement and can be used with capacitance pen probes.
4.6. NCV (Not-Contact Voltage) Pengukuran
- Tetapkan suis putar ke kedudukan "NCV".
- Gerakkan hujung atas multimeter dekat dengan volum ACtage sumber (cth, wayar hidup atau alur keluar).
- Peranti akan menunjukkan kehadiran volum ACtage through an audible beep and visual indicator (green for weak signal, red for strong signal).
Figure 4.3: The multimeter performing an NCV (Non-Contact Voltage) test. The display shows "--L" for a weak current signal (green indicator) and "--H" for a strong current signal (red indicator and buzzer alarm).
Figure 4.4: The multimeter's NCV function in use, detecting a live wire in an electrical outlet. The display shows "LIVE" indicating the presence of AC voltage.
4.7. Temperature Measurement (°C/°F)
- Set the rotary switch to the "Temp" position.
- Connect the temperature probe (K-type thermocouple) to the appropriate input jacks.
- Letakkan hujung prob pada atau berhampiran objek yang suhunya hendak diukur.
- Baca nilai suhu pada paparan.
Note: The complimentary temperature probe can only measure up to 300°C. For higher temperatures, a professional temperature probe is required.
