- Masukkan dua bateri AAA 1.5V, pastikan kekutuban (+ dan -) betul.
- Gantikan penutup petak bateri dan selamatkannya.
3.2 Menghubungkan Petunjuk Ujian
For most measurements, connect the test leads as follows:
- Masukkan petunjuk ujian hitam ke dalam bicu input "COM" (Umum).
- Insert the red test lead into the "INPUT" jack.
Ensure connections are firm before taking any measurements.
4. Arahan Operasi
The FY129C offers both auto identification and manual switching modes for various measurements.
Rajah 5: Illustration of the two measurement modes: Auto Identification (AC/DC voltage, frequency, resistance, continuity) and Manual Switching (AC/DC voltage, frequency, resistance, continuity, diode, capacitance, LIVE NCV).
4.1 Hidupkan/Mati Kuasa
Tekan ke Hidupkan kuasa button (labeled with a power symbol) to turn the multimeter on or off. The device features an auto-shutdown function to conserve battery power after a period of inactivity.
4.2 Auto Identification Mode
In auto identification mode, the multimeter automatically detects and measures AC/DC voltage, frequency, resistance, and continuity. Simply connect the test leads to the circuit or component, and the device will display the appropriate reading.
4.3 Manual Switching Mode
Tekan ke SEL button to cycle through manual measurement functions. The selected function will be indicated on the LCD.
- AC / DC Voltage Pengukuran: Connect test leads in parallel to the circuit. The multimeter can measure AC voltage from 0.8V to 500V and DC voltage dari 0.8V hingga 500V.
- Pengukuran Rintangan: Ensure the circuit is de-energized. Connect test leads across the component. Measures resistance from 30Ω to 60MΩ.
- Pengukuran Kekerapan: Connect test leads to the signal source. Measures frequency from 10Hz to 6000Hz.
- Ujian Kesinambungan: For checking if a circuit is complete. A low resistance reading (typically below 50Ω) indicates continuity, often accompanied by an audible beep.
- Ujian Diod: Measures the forward voltage drop of a diode. Connect the red lead to the anode and the black lead to the cathode.
- Pengukuran Kapasitan: Measures capacitance from 6nF to 60000µF. Ensure capacitors are discharged before testing.
Rajah 6: The FY129C multimeter displaying a capacitance measurement, indicating its ability to measure up to 60000µF.
- Pengukuran Suhu: Connect the provided thermocouple to the multimeter. Measures temperature from -20℃ to 1000℃.

4.4 Bukan Kenalan Voltage (NCV) and Live Wire Checking
Fungsi NCV membolehkan pengesanan vol ACtage tanpa sentuhan langsung, meningkatkan keselamatan.
- Tekan ke NCV LIVE button to activate NCV mode.
- Bring the top of the multimeter close to the wire or outlet. The NCV indicator and audible alerts will signal the presence of AC voltage.
- For Live Wire Checking, use the NCV LIVE function to distinguish between live and neutral wires in an AC circuit.

5. Ciri-ciri Tambahan
5.1 Pegangan Data
Tekan ke TAHAN button to freeze the current reading on the display. Press it again to release the hold function. This is useful for recording measurements in difficult-to-read situations.
5.2 Flashlight and Screen Backlight
The multimeter includes a built-in flashlight and screen backlight for improved visibility in dimly lit environments.
- Tekan ke Lampu suluh button (often integrated with the HOLD button or a separate button) to turn the flashlight on or off.
- The screen backlight typically activates automatically when the device is powered on or can be toggled with a dedicated button (if available).
5.3 Automatikan
To conserve battery life, the FY129C multimeter will automatically power off after a period of inactivity.

9. Maklumat Keselamatan
Always observe basic safety precautions when using electrical testing equipment to reduce the risk of fire, electric shock, or personal injury.
- Jangan gunakan multimeter jika ia kelihatan rosak atau jika wayar ujian telah rosak.
- Jangan gunakan voltage atau arus yang melebihi had maksimum yang ditentukan untuk multimeter.
- Berhati-hati semasa bekerja dengan voltagadalah melebihi 30V AC RMS, puncak 42V atau 60V DC. Ini voltagia menimbulkan bahaya kejutan.
- Always disconnect power to the circuit before measuring resistance, continuity, diode, or capacitance.
- Ensure your hands are dry and you are standing on an insulated surface when taking measurements.
- Use the correct function and range for each measurement.
- The NCV function is for indication only; always verify the absence of voltage with direct contact measurements before touching any conductors.
