1. Pastikan multimeter dimatikan dan petunjuk ujian diputuskan.
2. Cari penutup petak bateri di bahagian belakang peranti.
3. Gunakan pemutar skru untuk membuka penutup.
4. Insert the two AA batteries, observing the correct polarity (+/-).
5. Gantikan penutup petak bateri dan kencangkannya dengan skru.

4.2 Menghubungkan Petunjuk Ujian

Sentiasa sambungkan wayar ujian dengan betul untuk pengukuran yang tepat dan selamat.

• Masukkan wayar ujian hitam ke dalam bicu "COM" (biasa).
• Untuk kebanyakan ukuran (voltage, resistance, continuity, diode, capacitance, frequency, temperature), insert the red test lead into the "VΩHz" jack.
• For current measurements up to 600mA, insert the red test lead into the "mA" jack.
• For current measurements up to 10A, insert the red test lead into the "10A" jack.

5. Arahan Operasi

The multimeter features both automatic and manual ranging modes. Use the 'SEL' button to switch between functions within a single rotary switch position, and to toggle between auto and manual range if applicable.

This image illustrates the multimeter's rotary dial, highlighting the integrated design that allows users to select between automatic and manual measurement ranges for various functions.

5.1 DC / AC Voltage Pengukuran (V)

1. Turn the rotary switch to the V (DC) or V~ (AC) position.
2. Connect the red test lead to the positive side and the black test lead to the negative side of the circuit.
3. Baca voltagnilai e pada paparan.

5.2 DC/AC Current Measurement (A/mA/µA)

1. Turn the rotary switch to the A (DC) or A~ (AC) position, or mA/µA position.
2. Connect the multimeter in series with the circuit. Ensure the red test lead is in the appropriate current jack (10A or mA/µA).
3. Baca nilai semasa pada paparan.

5.3 Pengukuran Rintangan (Ω)

1. Turn the rotary switch to the Ω position.
2. Pastikan litar dinyahtenagakan sebelum mengukur rintangan.
