6.3 Common Measurements

• VoltagMesura (CA/CC):
  1. Connect the red lead to VΩmA and the black lead to COM.
  2. Seleccioneu el volum de CA o CC adequattagmode e.
  3. Connecteu les sondes de prova en paral·lel al circuit o component que s'està provant.
• Mesura de corrent (CA/CC):
  1. ADVERTIMENT: Ensure the circuit is de-energized before connecting the meter in series.
  2. For low current, connect the red lead to VΩmA; for high current (up to 10A), connect the red lead to 10A. Connect the black lead to COM.
  3. Select the appropriate AC or DC current mode.
  4. Connect the test probes in series with the circuit.
• Mesura de la resistència:
  1. Connect the red lead to VΩmA and the black lead to COM.
  2. Select the resistance mode (Ω).
  3. Ensure the circuit or component is de-energized before measuring resistance. Connect the probes across the component.
• Prova de continuïtat:
  1. Connect the red lead to VΩmA and the black lead to COM.
  2. Select the continuity mode (often indicated by a speaker icon).
