    Hazardous Voltage This product is designed for use with non-hazardous, live signals only. Ensure that all signals are isolated from hazardous, live circuits and that unsafe voltages are not present at the inputs. Exceeding the voltage specifications may cause electric shock or damage the product.
    Tension dangereuse Ce produit est conçu uniquement pour être utilisé avec des signaux en direct non dangereux. Assurez-vous que tous les signaux sont isolés des circuits dangereux sous tension et qu’aucune tension dangereuse n’est présente aux entrées. Le dépassement de la tension spécifiée peut provoquer un choc électrique ou endommager le produit.
    Caution Any external sources must be limited to not exceed these maximum rated currents.
    Attention Les sources externes doivent être limitées pour ne pas dépasser ces tensions nominales maximales.

    Measurement Category I Guidelines

    Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

    Note Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.
    Hazardous Voltage Do not connect the product to signals or use for measurements within Measurement Categories II, III, or IV.
    Tension dangereuse Ne pas connecter le produit à des signaux dans les catégories de mesure II, III ou IV et ne pas l'utiliser pour effectuer des mesures dans ces catégories.
    Hazardous Voltage Do not connect the product to signals or use for measurements within Measurement Categories II, III, or IV, or for measurements on MAINs circuits or on circuits derived from Overvoltage Category II, III, or IV which may have transient overvoltages above what the product can withstand. The product must not be connected to circuits that have a maximum voltage above the continuous working voltage, relative to earth or to other channels, or this could damage and defeat the insulation. The product can only withstand transients up to the transient overvoltage rating without breakdown or damage to the insulation. An analysis of the working voltages, loop impedances, temporary overvoltages, and transient overvoltages in the system must be conducted prior to making measurements.
    Tension dangereuse Ne pas connecter le produit à des signaux dans les catégories de mesure II, III ou IV et ne pas l'utiliser pour des mesures dans ces catégories, ou des mesures sur secteur ou sur des circuits dérivés de surtensions de catégorie II, III ou IV pouvant présenter des surtensions transitoires supérieures à ce que le produit peut supporter. Le produit ne doit pas être raccordé à des circuits ayant une tension maximale supérieure à la tension de fonctionnement continu, par rapport à la terre ou à d'autres voies, sous peine d'endommager et de compromettre l'isolation. Le produit peut tomber en panne et son isolation risque d'être endommagée si les tensions transitoires dépassent la surtension transitoire nominale. Une analyse des tensions de fonctionnement, des impédances de boucle, des surtensions temporaires et des surtensions transitoires dans le système doit être effectuée avant de procéder à des mesures.
