Channel-to-channel

None

Channel-to-earth ground

Continuous

60 V DC, Measurement Category I

Withstand

1,000 V RMS, verified by a 5 s dielectric withstand test

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.

Warning

 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.

Mise en garde

 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
