5. Gantikan penutup dan kencangkannya dengan skru.

4.2 Menghubungkan Petunjuk Ujian

Always connect the test leads correctly for accurate and safe measurements:

• Sambungkan petunjuk ujian hitam kepada COM bicu input (biasa).
• Untuk kebanyakan ukuran (voltage, resistance, capacitance, frequency, temperature, diode, continuity), connect the petunjuk ujian merah kepada VΩmA bicu input.
• Untuk pengukuran arus tinggi (sehingga 10A), sambungkan petunjuk ujian merah kepada 10A bicu input.

5. Mod Operasi

Turn the rotary switch to the desired function. Use the SELECT button to toggle between modes (e.g., AC/DC) if applicable.

5.1 Jldtage Pengukuran (DC/AC)

Untuk mengukur voltage:

1. Set the rotary switch to the 'V' (Voltage) kedudukan.
2. Use the SELECT button to choose between DC (V-) or AC (V~) voltage.
3. Sambungkan wayar ujian secara selari dengan litar atau komponen yang sedang diukur.

5.2 Pengukuran Semasa (DC/AC)

Untuk mengukur arus:

1. Set the rotary switch to the 'A' (Current) position.
2. Use the SELECT button to choose between DC (A-) or AC (A~) current.
3. Connect the test leads in series with the circuit. Ensure the circuit is open before connecting the meter.

5.3 Pengukuran Rintangan

Untuk mengukur rintangan:

1. Set the rotary switch to the 'Ω' (Resistance) position.
2. Ensure the circuit or component is de-energized before measuring.
3. Sambungkan petunjuk ujian merentasi komponen.

5.4 Pengukuran Kapasitansi

Untuk mengukur kapasiti:

1. Set the rotary switch to the 'F' (Capacitance) position.
2. Ensure the capacitor is fully discharged before measuring.
3. Sambungkan petunjuk ujian merentasi kapasitor.

5.5 Pengukuran Kekerapan
