4. Persediaan

4.1 Pemasangan Bateri

The Irfora ST212 requires two 1.5V AAA batteries (not included) for operation.

1. Cari penutup petak bateri di belakang meter.
2. Gunakan pemutar skru untuk membuka petak bateri.
3. Masukkan dua bateri AAA 1.5V, pastikan kekutuban (+ dan -) betul.
4. Gantikan penutup petak bateri dan kencangkannya dengan skru.

Note: Remove batteries if the meter is not used for an extended period to prevent leakage and damage.

5. Arahan Operasi

The meter features automatic ranging for most functions, simplifying operation. Use the 'SEL' button to switch between AC/DC modes or different sub-functions (e.g., resistance, diode, continuity).

5.1 Hidupkan/Mati Kuasa

Tekan ke Butang kuasa (usually integrated with the SEL button) to turn the meter on. The meter will automatically shut down after approximately 15 minutes of inactivity to conserve battery life. Press the Power button again to turn it off manually.

5.2 Pengukuran Arus AC/DC (Clamp)

Figure 5.1: Non-contact current measurement using the clamp jaw, capable of measuring up to 400A.

1. Hidupkan meter.
2. Select the current measurement mode (usually indicated by 'A' or 'ACA/DCA'). Use the SEL button to switch between AC and DC current if necessary.
3. Buka clamp jaw and enclose only one conductor of the circuit. Ensure the jaw is fully closed.
4. Baca nilai semasa pada paparan.
5. The meter supports up to 400A AC/DC current measurement.

5.3 AC/DC Jldtage Pengukuran

1. Masukkan petunjuk ujian merah ke dalam VΩHz terminal dan petunjuk ujian hitam ke dalam COM terminal.
2. Pilih voltage measurement mode (usually indicated by 'V' or 'ACV/DCV'). Use the SEL butang untuk bertukar antara volum AC dan DCtage.
3. Sambungkan petunjuk ujian secara selari dengan litar atau komponen yang ingin anda ukur.
4. Baca voltagnilai e pada paparan.

5.4 Resistance, Diode, and Continuity Measurement

1. Masukkan petunjuk ujian merah ke dalam VΩHz terminal dan petunjuk ujian hitam ke dalam COM terminal.
2. Select the resistance/diode/continuity mode (usually indicated by 'Ω', 'Diode symbol', or 'Continuity symbol').
3. Gunakan SEL button to cycle through Resistance (Ω), Diode Test, and Continuity Test.
4. For Resistance: Connect the test leads across the component. Read the resistance value.
5. Untuk Ujian Diod: Connect the red lead to the anode and the black lead to the cathode. Read the forward voltage drop. Balikkan petunjuk untuk memeriksa litar terbuka.
6. For Continuity: Connect the test leads across the circuit. A built-in buzzer will sound if continuity is detected (resistance below a certain threshold).

5.5 Pengukuran Kapasitansi
