Safety Information
Usage Precautions
The high-voltage probe is designed to prevent accidental shock to the operator when
properly used. This operating note must be read and understood prior to using the
probe. Improper procedure or incorrect analysis of the measurement situation can
result in serious shock.
La sonde haute tension est conçue pour éviter les chocs accidentels à l’opérateur
lorsqu’elle est correctement utilisée. Cette notice d’utilisation doit être lue et comprise
avant d’utiliser la sonde. Une procédure incorrecte ou une analyse incorrecte de la
situation de mesure peut entraîner un choc grave.
This high-voltage probe must only be used by personnel who are trained, experienced,
or otherwise qualied to recognize hazardous situations and who are trained to the
safety precautions that are necessary to avoid possible injury when using such a de-
vice.
Cette sonde haute tension ne doit être utilisée que par du personnel formé, expéri-
menté ou autrement qualié pour reconnaître les situations dangereuses et qui est
formé aux précautions de sécurité nécessaires pour éviter les blessures possibles lors
de l’utilisation d’un tel appareil.
When measuring higher frequency signals, be sure to comply with the Voltage vs
Frequency Derating Curve. Do not apply to the input any potential that exceeds the
maximum rating of the probe.
Lors de la mesure de signaux de fréquence plus élevée, assurez-vous de respecter la
courbe de déclassement tension/fréquence. N’appliquez à l’entrée aucun potentiel qui
dépasse la valeur nominale maximale de la sonde.
This high-voltage probe is designed for use with Measurement Category other than
II, III and IV only (formally CAT I). Do not use the probe for measurements performed
on circuits dened by any other measurement category or transient overvoltages of
more than 1500 V. Refer to IEC Measurement Category Denitions on page 9 for a
denition of measurement categories.
Cette sonde haute tension est conçue pour être utilisée avec des catégories de
mesure autres que II, III et IV uniquement (anciennement CAT I). N’utilisez pas la
sonde pour des mesures effectuées sur des circuits dénis par une autre catégorie de
mesure ou des surtensions transitoires de plus de 1 500 V. Reportez-vous à Déni-
tions des catégories de mesure CEI à la page 9 pour une dénition des catégories
de mesure.
The ground lead is critical to the safe operation of the probe. Failure to make this
connection when making high-voltage measurements may result in personal injury or
damage to the probe or oscilloscope. This connection must always be made BEFORE
the probe tip comes in contact with the high voltage and must not be removed until the
probe tip has been removed from the high-voltage source.

Le l de terre est essentiel au fonctionnement sûr de la sonde. Le non-respect de cette
connexion lors de mesures à haute tension peut entraîner des blessures corporelles
ou endommager la sonde ou l’oscilloscope. Cette connexion doit toujours être effec-
tuée AVANT que la pointe de la sonde n’entre en contact avec la haute tension et
ne doit pas être retirée tant que la pointe de la sonde n’a pas été retirée de la source
haute tension.
Do not exceed 60 seconds of contact between the probe and the circuit-under-test
when measuring voltages ≥8 kV DC, ≥5 kV ACrms, or ≥15 kVpk-pk AC. It is recom-
mended to wait 5 minutes between measurements.
Ne pas dépasser 60 secondes de contact entre la sonde et le circuit à tester lors de la
mesure de tensions ≥8 kV DC, ≥5 kV ACrms ou ≥15 kVpk-pk AC. Il est recommandé
d’attendre 5 minutes entre les mesures.
Hands, shoes, oor, and work bench must be dry. Avoid making measurements under
humidity, dampness, or other environmental conditions that might affect safety.
Les mains, les chaussures, le sol et l’établi doivent être secs. Évitez d’effectuer des
mesures dans des conditions d’humidité, d’humidité ou d’autres conditions environne-
mentales susceptibles d’affecter la sécurité.
To avoid injury, remove jewelry such as rings, watches, and other metallic objects. Do
not touch exposed connections and components when power is present.
Pour éviter les blessures, retirez les bijoux tels que bagues, montres et autres objets
métalliques. Ne touchez pas les connexions et composants exposés lorsque l’alimen-
tation est présente.
Do not work alone when working with high-Voltage Circuits.
Ne travaillez pas seul lorsque vous travaillez avec des circuits à haute tension.
The probe is designed to be used in ofce-type indoor environments.
• Do not operate in the presence of noxious, corrosive, ammable fumes, gases,
vapors, chemicals, or nely-divided particulates.
• Hands, shoes, oor, and workbench must be dry. Avoid making measurements
under humid, damp, or other environmental conditions that might effect the safety of
the measurement situation.
• The probe body should be kept clean and free of any conductive contamination.
Refer to the section on cleaning.
La sonde est conçue pour être utilisée dans des environnements intérieurs de type
bureau.
• Ne pas utiliser en présence de fumées nocives, corrosives, inammables, de gaz,
de vapeurs, de produits chimiques ou de particules nement divisées.

• Les mains, les chaussures, le sol et l’établi doivent être secs. Évitez d’effectuer des
mesures dans des conditions environnementales humides, humides ou autres qui
pourraient affecter la sécurité de la situation de mesure.
• Le corps de la sonde doit être maintenu propre et exempt de toute contamination
conductrice. Reportez-vous à la section sur le nettoyage.
To reduce the risk of shock or re:
• Connect the probe to the oscilloscope before connecting probe to the circuit under
test. Disconnect the probe input from the circuit before disconnecting the probe from
the oscilloscope.
• Do not exceed the voltage rating category rating of the probe. Use only accessories
provided with probe.
• Keep nger behind the nger guard of the probe body.
• For your own safety, inspect the probe for cracks and frayed or broken leads before
each use. If defects are noted, DO NOT use the probe.
• Keep the probe’s output cables away from the circuit under test, as they are not
intended to be in contact with these circuits.
Pour réduire le risque de choc ou d’incendie:
• Connectez la sonde à l’oscilloscope avant de connecter la sonde au circuit à tester.
Déconnectez l’entrée de la sonde du circuit avant de déconnecter la sonde de l’os-
cilloscope.
• Ne dépassez pas la catégorie de tension nominale de la sonde. Utilisez uniquement
les accessoires fournis avec la sonde.
• Gardez le doigt derrière le protège-doigts du corps de la sonde.
• Pour votre propre sécurité, inspectez la sonde à la recherche de ssures et de ls
eflochés ou cassés avant chaque utilisation. Si des défauts sont constatés, NE
PAS utiliser la sonde.
• Gardez les câbles de sortie de la sonde éloignés du circuit à tester, car ils ne sont
pas destinés à être en contact avec ces circuits.
It is advisable to turn the high-voltage source off before connecting or disconnecting
the probe.
Il est conseillé d’éteindre la source haute tension avant de connecter ou de déconnect-
er la sonde. Éteindre la source haute tension.
Do not attempt to take measurements where the source and the test instrument chas-
sis or return lead is not properly grounded.

bution part of a building’s low-voltage mains installation.
Measurement Category IV (CAT IV): test and measuring circuits connected at the
source of the building’s low-voltage mains installation.
Pollution - addition of foreign matter, solid, liquid, or gaseous (ionized gases) that may produce a reduc-
tion of dielectric strength or surface resistivity.
