4. Persediaan
4.1 Pemasangan Bateri
The PeakTech P 3131 requires two 1.5V AAA batteries (included). To install or replace batteries:
- Pastikan peranti dimatikan.
- Cari penutup petak bateri di bahagian belakang meter.
- Gunakan pemutar skru untuk membuka petak.
- Insert the two AAA batteries, observing correct polarity (+ and -).
- Gantikan penutup petak bateri dan kencangkannya dengan skru.
Apabila penunjuk bateri rendah muncul pada paparan, gantikan bateri dengan segera untuk memastikan pengukuran yang tepat.
4.2 Menghubungkan Petunjuk Ujian
Untuk voltage, resistance, and continuity measurements, connect the supplied test leads:
- Masukkan petunjuk ujian hitam ke dalam COM (common) input terminal.
- Masukkan petunjuk ujian merah ke dalam VΩ terminal input.

5. Arahan Operasi
5.1 Hidupkan/Mati Kuasa
Rotate the function selector dial from the "OFF" position to any desired measurement function to power on the meter. To power off, rotate the dial back to "OFF". The meter features an automatic power-off function (can be deactivated) to conserve battery life.
5.2 Pengukuran Arus AC/DC (Clamp)
Untuk mengukur arus tanpa memutuskan litar:
- Putar dail pemilih fungsi ke A~ (Arus AC) atau A= kedudukan (Arus DC).
- Tekan ke AC/DC button if you need to switch between AC and DC current modes (if the dial position combines them).
- Tekan ke SIFAR button to zero the display before measuring DC current, especially for small currents, to compensate for residual magnetism.
- Buka clamp rahang dengan menekan picu.
- Enclose only satu conductor with the clamp rahang. Pastikan rahang ditutup sepenuhnya.
- Baca nilai semasa pada paparan LCD.

5.3 AC/DC Jldtage Pengukuran
Untuk mengukur voltage:
- Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 4.2.
- Putar dail pemilih fungsi ke V~ (Jilid ACtage) atau V= (DC Voltage) kedudukan.
- Sambungkan prob ujian secara selari dengan litar atau komponen yang ingin anda ukur.
- Baca voltagnilai e pada paparan LCD.
5.4 Resistance and Continuity Measurement
To measure resistance or check for continuity:
- Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 4.2.
- Putar dail pemilih fungsi ke Ω/))) (Resistance/Continuity) position.
- For resistance: Connect the test probes across the component. Ensure the circuit is de-energized.
- For continuity: Touch the test probes to the two points you want to check. A continuous beep indicates a low-resistance path (continuity).
- Baca nilai rintangan pada paparan LCD.
5.5 Fungsi Khas
- RMS Benar: The meter measures True Root Mean Square values for AC voltage and current, providing accurate readings for non-sinusoidal waveforms.
- Pegangan Data (H): Tekan ke H/MAX button briefly to freeze the current reading on the display. Press again to release.
- Maximum Value Hold (MAX): Tekan dan tahan butang H/MAX button to capture and display the maximum measured value. Press again to exit.
- ZERO Function: Used to zero the display for DC current measurements to eliminate offset errors.
- Auto Ranging: The meter automatically selects the appropriate measurement range.
- Auto Matikan: The meter automatically turns off after a period of inactivity to save battery. This feature can typically be disabled by holding a specific button during power-on (refer to the device's on-screen indicators or a more detailed manual if available).
6. Penyelenggaraan
