9.6 TEST DE BATTERIE (1.5 V/9 V)
précision de base
± (5.0 % de la lecture + 5 chiffres)
protection de surcharge
fusible 0.5 A/600 V
10. Mesurer la tension
Ne pas effectuer des mesures dans un circuit pouvant avoir une
tension > 500 V
Être extrêmement prudent lors d’une mesure d’une tension >
60 VCC ou 30 VCA rms.
Toujours placer vos doigts derrière la protection des sondes de
mesure!
10.1 MESURER LA TENSION CONTINUE
1. Connecter le cordon de mesure rouge à la borne "VmA et le cordon
de mesure noir à la borne "COM".
2. Mettre le commutateur rotatif dans la position V souhaitée. Mettre
le commutateur dans sa position maximum dans le cas où la tension
CC à mesurer est inconnue. Ensuite diminuer la tension graduellement
afin de trouver la résolution idéale.
3. Connecter les cordons de mesure à la source de mesure.
4. L'intensité de la tension et la polarité du cordon rouge se visualisent
sur l'afficheur LCD.
10.2 MESURER LA TENSION ALTERNATIVE
1. Connecter le cordon de mesure rouge à la borne "VmA" et le cordon
noir à la borne "COM".
2. Mettre le commutateur rotatif dans la position V~ souhaitée.
3. Connecter les cordons de mesure à la source de mesure.
4. La valeur de la charge mesurée se visualise sur l'afficheur LCD.
11. Mesurer le courant continu
Ne pas effectuer des mesures dans un circuit pouvant avoir une
tension > 500 V
Être extrêmement prudent lors d’une mesure d’une tension
> 60 VCC.
Toujours placer vos doigts derrière la protection des sondes de
mesure!
1. Connecter le cordon de mesure rouge à la borne "VmA" et le cordon
de mesure noir à la borne "COM" (connecter le cordon de mesure
rouge à la borne "10A" pour des mesures entre 200 mA et 10 A).
