probe assembly may be impaired.
N’utilisez pas votre sonde d’une manière non spéci ée par le fabricant. Sachez que
s’il est utilisé d’une manière non spéci ée par le fabricant, la protection fournie par
l’ensemble de sonde peut être altérée.
The Probe Must be Grounded.
Before making connections to the input leads of the probe, ensure that the output
BNC connector is attached to the BNC input channel of the oscilloscope AND the
oscilloscope is properly grounded.
La sonde doit être mise à la terre.
Avant d’effectuer les connexions aux ls d’entrée de la sonde, assurez-vous que le
connecteur BNC de sortie est connecté au canal d’entrée BNC de l’oscilloscope ET
que l’oscilloscope est correctement mis à la terre.
Connect and Disconnect the Probe Properly.
Connect the probe to the oscilloscope before connecting the probe inputs to the circuit
under test. Disconnect the probe inputs from the circuit under test before disconnecting
the probe from the oscilloscope.
Connectez et déconnectez correctement la sonde.
Connectez la sonde à l’oscilloscope avant de connecter les entrées de la sonde
au circuit à tester. Déconnectez les entrées de la sonde du circuit à tester avant de
déconnecter la sonde de l’oscilloscope.
Observe Maximum Working Voltages.
To avoid injury, do not use the probes above 1000 Vrms in a CAT III environment
between each input lead and earth or between the two input leads.
Do not operate the CT4447-2 probe above 1000 Vrms mains isolated (200x

When it is likely that the ground protection is impaired, you must make the instrument
inoperative and secure it against any unintended operation.
Lorsqu’il est probable que la protection au sol soit altérée, vous devez rendre
l’instrument inopérant et le sécuriser contre tout fonctionnement intempestif.
The probe and its cables are sensitive parts and therefore, you should be careful not
to damage them though excessive bending or pulling. Avoid any mechanical shocks to
the probe to guarantee accurate performance and protection.
La sonde et ses câbles sont des pièces sensibles et, par conséquent, vous devez faire
attention à ne pas les endommager en les pliant ou en tirant excessivement. Évitez
tout choc mécanique sur la sonde pour garantir des performances et une protection
précises.
