3.1 Ngukur DC Voltage (DCV)
- Set the rotary dial to the desired DCV range (e.g., 200m, 2, 20, 200, 1000). Choose a range higher than the expected voltage.
- Connect the red lead to the positive (+) side of the circuit and the black lead to the negative (-) side.
- Baca voltage nilai dina tampilan.
3.2 Ngukur AC Voltage (ACV)
- Set the rotary dial to the desired ACV range (e.g., 200m, 2, 20, 200, 750). Choose a range higher than the expected voltage.
- Sambungkeun kabel uji kana voltase ACtage source. Polarity does not matter for AC voltage.
- Baca voltage nilai dina tampilan.
3.3 Ngukur Résistansi (Ω)
- Pastikeun sirkuit atanapi komponén parantos dipareuman énergina sateuacan ngukur résistansi.
- Set the rotary dial to the desired Ω range (e.g., 200, 2K, 20K, 200K, 2M, 20M, 200M).
- Sambungkeun lead test kana komponén anu bakal diukur.
- Maca nilai résistansi dina tampilan.
3.4 Measuring DC Current (DCA)
- Pastikeun sirkuit de-energized.
- Set the rotary dial to the desired DCA range (e.g., 200µ, 2m, 20m, 200m, 10A).
- penting: For currents up to 200mA, use the 'V-Ω-mA' jack for the red lead. For currents up to 10A, use the '10A' jack.
- Break the circuit and connect the multimeter in series with the load. The current must flow through the multimeter.
- Re-energize the circuit and read the current value.
3.5 Measuring AC Current (ACA)
- Pastikeun sirkuit de-energized.
- Set the rotary dial to the desired ACA range (e.g., 200µ, 2m, 20m, 200m, 10A).
- penting: For currents up to 200mA, use the 'V-Ω-mA' jack for the red lead. For currents up to 10A, use the '10A' jack.
- Break the circuit and connect the multimeter in series with the load.
- Re-energize the circuit and read the current value.
3.6 Measuring Capacitance (CX)
- Pastikeun kapasitor discharged pinuh saméméh nguji.
