Safety Information

To ensure safe operation and service of the meter, follow these instructions. Failure to observe warnings can result in severe injury or death.

Q Avoid working alone so assistance can be rendered. Q To enhance safety, test leads should be disconnected from

instrument when not in use

Q Do not use test leads or the clamp meter if they

look damaged

Q Do not use the clamp meter if the tester is not operating

properly or if it is wet.

Q Use the clamp meter only as speciﬁed in the instruction card or the protection provided by the clamp meter may be impaired.

Q Special precautions are necessary when operating in situations where exposed live parts at dangerous voltages may be encountered. Personal protective equipment (not supplied with the instrument) should be used.

Q The test leads should be disconnected from the instrument when making a current measurement.

Q Use caution with voltages above 30 V AC RMS, or 60 V DC. These voltages pose a shock hazard.

Zero

Using the Relative mode (REL), a stable value can be stored, the instrument zeroed at that point, and then any variation from that value is displayed as a direct measurement relative to the stable value.

2. Make a measurement and then press the ZERO button. REL: Meter stores the measured value after pressing the ZERO button.

3. REL (ﬂashing): The meter saves the offset value. Present value is displayed.

1. Normal: Press and hold ZERO for > 2 seconds to return to normal operation and cancel the offset value.

Informations de sécurité

Appliquez les instructions suivantes aﬁn de garantir le fonctionnement et l’entretien de la pince en toute sécurité. Le non-respect des consignes peut causer de graves blessures ou la mort.

Q Évitez de travailler seul pour pouvoir vous faire aider. Q Pour plus de sécurité, débranchez les cordons de test de l’instrument

lorsque vous ne l’utilisez pas.

Q N’utilisez pas les cordons de test ni la pince ampèremétrique s’ils vous

semblent endommagés.

Q N’utilisez pas la pince ampèremétrique si elle ne fonctionne pas

correctement ou si elle est mouillée.

Q Utilisez toujours la pince ampèremétrique conformément aux instructions. À défaut, vous risqueriez d’altérer la protection intégrée à cette dernière.

Q Des précautions particulières doivent être prises lorsque vous travaillez dans environnement comportant des pièces alimentées par une tension dangereuse. Utilisez un équipement de protection individuelle (non fourni avec l’instrument).

Q Débranchez les cordons de test de l’instrument lorsque vous mesurez le courant.

Q Faites preuve de prudence lorsque la tension dépasse 30 V C.A. RMS ou 60 V C.C. Ces tensions présentent un risque d’électrocution.

Zero

Il est possible d’enregistrer une valeur stable à l’aide du mode relatif (REL), l’instrument se met à zéro à ce point, puis toute variation de cette valeur s’afﬁche comme mesure directe par rapport à la valeur stable.

2. Effectuez une mesure puis appuyez sur le bouton ZERO (Zéro). REL (mode relatif) : Une fois que vous avez appuyé sur le bouton ZERO (Zéro), la pince enregistre la valeur mesurée.

3. REL (clignotant) : La pince enregistre la valeur de décalage. La valeur présente s’afﬁche.

1. Normal : Appuyez sur le bouton ZERO (Zéro) et maintenez-le enfoncé plus de deux secondes pour revenir au fonctionnement normal et annuler la valeur de décalage.

Maintien des données

Maintien min./max.

2. MAX (Max.) : La pince enregistre la valeur maximale et minimale. La valeur maximale s’afﬁche.

3. MIN (Min.) : La pince enregistre la valeur maximale et minimale. La valeur minimale s’afﬁche.

4. MAX MIN (Max. Min.) (clignotant) : La pince enregistre la valeur maximale et minimale. La valeur présente s’afﬁche.

1. Normal : Appuyez sur le bouton MIN MAX (Min. Max.) et maintenez le enfoncé pour revenir au fonctionnement normal.
