  • Putar dail fungsi ke A kedudukan.
  • Gunakan SEL/ZERO button to select AC (A~) or DC (A=) current.
  • Tekan clamp tuil pelepas untuk membuka clamp Rahang.
  • Masukkan hanya satu konduktor litar dalam clamp Rahang.
  • For DC current, press SEL/ZERO to zero the reading before measurement if necessary.
  • Baca nilai semasa pada paparan.

5.4. Resistance (Ω), Continuity, Diode Test

  • Putar dail fungsi ke Ω kedudukan.
  • Gunakan SEL/ZERO button to cycle between Resistance, Continuity, and Diode Test modes.
  • Rintangan: Connect test leads across the component. Ensure the circuit is de-energized.
  • Kesinambungan: If resistance is below approximately 30Ω, the buzzer will sound.
  • Ujian Diod: Connect the red lead to the anode and black lead to the cathode. The display shows the forward voltage drop. Balikkan petunjuk untuk memeriksa litar terbuka.
