Caution Observe all instructions and cautions in the user documentation. Using the product in a manner not specified can damage the product and compromise the built-in safety protection.
Attention Suivez toutes les instructions et respectez toutes les mises en garde de la documentation d'utilisation. L'utilisation du produit de toute autre façon que celle spécifiée risque de l'endommager et de compromettre la protection de sécurité intégrée.

Safety Voltages

Connect only voltages that are within these limits.

Table 6. Safety Voltages
Supported measurement range[1]1 If the total voltage sourced or driven on any pin relative to GND exceeds the supported measurement range, instrument performance may be degraded. -2 V to 7 V[2]2 Voltage > 6 V requires the Extended Voltage Range mode of operation.
Measurement Category CAT I

Measurement Category

Caution Do not connect the product to signals or use for measurements within Measurement Categories II, III, or IV.
Attention 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.

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.

1 If the total voltage sourced or driven on any pin relative to GND exceeds the supported measurement range, instrument performance may be degraded.

2 Voltage > 6 V requires the Extended Voltage Range mode of operation.
