5. Petunjuk Pengoperasian
5.1 Fungsi Multimeter
The KKM828 offers a comprehensive range of multimeter measurement capabilities. Always connect test leads correctly to the appropriate input jacks (e.g., COM, VΩHz, mA, 10A) for the selected function.
- Tegangan AC/DCtage Pengukuran: Rotate the dial to the 'V~' or 'V=' position. Connect test leads in parallel with the circuit.
- Pengukuran Arus AC/DC: Rotate the dial to the 'mA~', 'mA=', '10A~', or '10A=' position. Connect test leads in series with the circuit.
- Pengukuran Resistansi: Rotate the dial to the 'Ω' position. Ensure the circuit is de-energized before measuring resistance.
- Pengukuran Kapasitansi: Rotate the dial to the 'mF' position. Discharge capacitors before measurement.
- Frequency and Duty Cycle Measurement: Rotate the dial to the 'Hz%' position.
- Tes Dioda: Rotate the dial to the 'Diode' position. Connect leads across the diode to check forward voltagjatuh.
- Uji Kontinuitas: Rotate the dial to the 'Continuity' position. The device will beep if resistance is below approximately 50Ω.
