2.2 Connexion des cordons de test
The multimeter comes with two test leads, typically one red (positive) and one black (negative/common). Proper connection is crucial for accurate and safe measurements.
- Pour la plupart des volstage, resistance, and low current measurements, connect the black lead to the 'COM' (Common) jack.
- Connect the red lead to the 'V-Ω-mA' jack for voltage, résistance et milliampmesures actuelles.
- For high current measurements (up to 10A), connect the red lead to the '10A' jack. Always ensure the correct jack is used to prevent damage to the meter or circuit.

3.1 Mesure du volume CCtage (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.
- Lire le voltage valeur sur l'affichage.
3.2 Mesure du volume CAtage (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.
- Connectez les cordons de test aux bornes du potentiel alternatif.tagsource e. La polarité n'a pas d'importance pour le volume alternatiftage.
- Lire le voltage valeur sur l'affichage.
3.3 Mesure de la résistance (Ω)
- Assurez-vous que le circuit ou le composant est hors tension avant de mesurer la résistance.
- Set the rotary dial to the desired Ω range (e.g., 200, 2K, 20K, 200K, 2M, 20M, 200M).
- Connectez les cordons de test aux bornes du composant à mesurer.
- Lisez la valeur de résistance sur l'écran.
3.4 Measuring DC Current (DCA)
- Assurez-vous que le circuit est hors tension.
- Set the rotary dial to the desired DCA range (e.g., 200µ, 2m, 20m, 200m, 10A).
- Important: 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.
- Remettez le circuit sous tension et lisez la valeur du courant.
3.5 Measuring AC Current (ACA)
- Assurez-vous que le circuit est hors tension.
- Set the rotary dial to the desired ACA range (e.g., 200µ, 2m, 20m, 200m, 10A).
- Important: For currents up to 200mA, use the 'V-Ω-mA' jack for the red lead. For currents up to 10A, use the '10A' jack.
- Coupez le circuit et connectez le multimètre en série avec la charge.
- Remettez le circuit sous tension et lisez la valeur du courant.
3.6 Measuring Capacitance (CX)
- S'assurer que le condensateur est complètement déchargé avant de procéder au test.
- Set the rotary dial to the CX range (e.g., 2n, 20n, 200n, 2µ, 20µ).
- Connectez les cordons de test aux bornes du condensateur.
- Lire la valeur de capacité sur l'écran.
3.7 Diode and Transistor (hFE) Testing
Refer to the specific markings on the dial for diode and transistor testing functions. Typically, diode test mode allows checking the forward voltage drop of a diode, and hFE mode is used for measuring the DC current gain of transistors.
