6.1 Mesures bàsiques

To perform a measurement, turn on the multimeter. The device will automatically select the appropriate range for most measurements (Auto Range). Select the desired function using the mode buttons.

• Voltage (AC/DC): Connect test leads in parallel to the circuit. Use the 'V~Hz' button to switch between AC and DC voltage.
• Corrent (CA/CC): Connect test leads in series with the circuit. Use the 'mA' or 'A' input jacks and the corresponding function button.
• Resistència (Ω): Ensure the circuit is de-energized. Connect test leads across the component.
• Capacitat: Ensure the capacitor is discharged before testing. Connect test leads across the capacitor.
• Prova de díode: Connect test leads across the diode. The display will show the forward voltage gota.
• Prova de continuïtat: Connect test leads across the circuit or component. A buzzer will sound if continuity is detected (low resistance).
• Freqüència (Hz): Connect test leads to the circuit.
