Arahan Operasi

This section details how to perform various measurements using your multimeter.

Image: Visual representation of the multimeter's versatile functions, including AC/DC Voltage, AC/DC Current, Diode, Continuity, Ampere, Capacity, Battery Test, Resistance, and Transistor measurements.

Mengukur DC Voltage (VDC)

1. Sambungkan plumbum ujian hitam ke COM bicu dan ujian merah membawa kepada VΩmA jek.
2. Turn the function switch to the desired VDC range (e.g., 200mV, 2V, 20V, 200V, 600V). If unsure, start with the highest range and decrease as needed.
3. Sambungkan wayar ujian secara selari merentasi komponen atau litar yang hendak diukur.
4. Baca voltagnilai e pada paparan LCD.

Mengukur Vol ACtage (VAC)

1. Sambungkan plumbum ujian hitam ke COM bicu dan ujian merah membawa kepada VΩmA jek.
2. Turn the function switch to the desired VAC range (e.g., 200V, 600V).
3. Sambungkan petunjuk ujian secara selari merentasi vol ACtage sumber.
4. Baca voltagnilai e pada paparan LCD.

Measuring DC Current (ADC)

PERHATIAN: Never connect the multimeter in parallel when measuring current. Always connect it in series with the circuit. Improper connection can damage the multimeter or the circuit.

1. Matikan kuasa litar.
2. For currents up to 200mA, connect the black test lead to the COM bicu dan ujian merah membawa kepada VΩmA jek.
3. For currents up to 10A, connect the black test lead to the COM bicu dan ujian merah membawa kepada 10A jek.
