4. Persediaan

Before using your HANMATEK CM10 Digital Clamp Multimeter, you need to install the batteries.

4.1 Pemasangan Bateri

1. Cari penutup petak bateri di belakang meter.
2. Gunakan pemutar skru untuk membuka petak bateri.
3. Masukkan dua bateri AAA, pastikan kekutuban (+ dan -) betul.
4. Gantikan penutup petak bateri dan kencangkannya dengan skru.

Rajah 4.1: The HANMATEK CM10 Digital Clamp Multimeter package includes the meter, a carrying case, test leads, and two AAA batteries for operation.

5. Arahan Operasi

This section details how to use your HANMATEK CM10 for various measurements. Always ensure the meter is set to the appropriate function before connecting to a circuit.

Rajah 5.1: The HANMATEK CM10 is widely used for various applications including air conditioning maintenance, household socket detection, car maintenance, and industrial electricity detection.

5.1 Pengukuran Arus AC

1. Turn the rotary switch to the '200A~' or '20A~' range for AC current.
2. Press the pliers trigger to open the clamp Rahang.
3. Enclose only one conductor of the circuit with the clamp rahang. Pastikan rahang ditutup sepenuhnya.
4. Baca nilai semasa AC pada paparan LCD.

5.2 AC/DC Jldtage Pengukuran

1. Insert the red test lead into the 'INPUT' jack and the black test lead into the 'COM' jack.
2. Turn the rotary switch to the 'V~' for AC voltage atau 'V=' untuk DC voltage.
3. Sambungkan petunjuk ujian secara selari dengan litar atau komponen yang ingin anda ukur.
4. Baca voltagnilai e pada paparan LCD.

5.3 Pengukuran Rintangan, Diod dan Kesinambungan

1. Insert the red test lead into the 'INPUT' jack and the black test lead into the 'COM' jack.
2. Putar suis putar ke kedudukan 'Ω'.
3. For Resistance: Connect the test leads across the component.
4. For Diode: Connect the red lead to the anode and the black lead to the cathode. The display will show the forward voltage drop. Balikkan petunjuk untuk memeriksa litar terbuka.
5. For Continuity: Connect the test leads across the circuit. If the resistance is below approximately 50Ω, the buzzer will sound.

5.4 NCV (Not-Contact Voltage) Ujian

1. Putar suis putar ke kedudukan 'NCV'.
2. Move the top part of the meter (induction probe) close to the conductor or electrical outlet you want to test.
3. Sekiranya AC voltage is detected, the meter will emit an audible beep and the NCV indicator light will flash. The display will show 'EF'. The NCV measurement range is 90-1000V.
