Notes about Usage
WARNING
• Do not clamp bare conductors to avoid short circuits or personal injury
when the sensor head is open or measuring.
• Be careful not to damage the insulation surface of the conductor under
measurement.
• Connect the power supply to the probe power terminal (option) of a
waveform measuring instrument such as Yokogawa DL/DLM series, or
use the power supply 701934 or 700938.
• Be careful of electric shock when connecting the probe to the device
under measurement.
• Read and observe the safety precautions of the instruments to be
connected to.
• To avoid electric shock, do not get the instrument wet or use it with wet
hands.
French
AVERTISSEMENT
• Ne serrez pas les conducteurs nus pour éviter les courts-circuits ou
les blessures lorsque la tête du capteur est ouverte ou en mesure de
mesurer.
• Veillez à ne pas endommager la surface d’isolation du conducteur à
mesurer.
• Connectez l’alimentation à la borne d’alimentation de la sonde (option)
d’un instrument de mesure de forme d’onde tel que la série Yokogawa
DL/DLM, ou utilisez l’alimentation 701934 ou 700938.
• Faites attention aux chocs électriques lors de la connexion de la
sonde à l’appareil à mesurer.
• Lisez et respectez les consignes de sécurité des instruments auxquels
vous souhaitez vous connecter.
• Pour éviter les chocs électriques, ne mouillez pas l’instrument et ne
l’utilisez pas avec les mains mouillées.

iv IM 701930-01E
CAUTION
• Do not subject the instrument to vibrations or shocks when transporting
and handling it. Be especially careful to avoid dropping it.
• Do not store or operate the instrument in an environment with direct
sunlight, high temperature, high humidity, or condensation. The
instrument may be deformed, or deteriorated in insulation, and it may
not meet the specifications.
• Before using the instrument, inspect and check the operation for
malfunctions due to storage or transport conditions. If a malfunction is
found, contact your dealer or YOKOGAWA representative.
• The instrument is not dustproof or waterproof. Do not use it in a dusty or
wet environment.
• The sensor head is a precision assembly composed of a molded
component, a ferrite core and a Hall effect element. Handle the
instrument with care as it may be damaged by sudden changes in
ambient temperature, mechanical stress or shock.
• The matching surfaces of the sensor head are precision ground. Handle
the instrument with care as scratches on the surfaces may impair
performance.
• Gently wipe off any dust or dirt on the matching surfaces of the sensor
head with a soft cloth. It may generate resonance noise or impair
performance.
• Do not bend or pull the sensor cable or power cable to avoid damage
due to disconnection.
• Current sensors can be damaged by static electricity. Be careful not to
apply static electricity to the instrument including the following cases.
• Touching the sensor head with an object charged with static electricity
• Touching the sensor head with an object with an electrical potential
difference
• A user charged with static electricity touching the core surface when
cleaning the matching surfaces of the sensor head
(When cleaning the surfaces, take static electricity measures such as
wearing an antistatic wrist strap.)
• Gently wipe the instrument with a soft cloth moistened with a small
amount of water or mild detergent. Do not use detergents containing
organic solvents such as benzine, alcohol, acetone, ethers, ketones,
thinners or gasoline. They may deform or discolor the instrument.
• When the power is on, keep the sensor head closed, except when
clamping the conductor under measurement. Leaving it open may
damage the instrument.

ATTENTION
• Ne soumettez pas l’instrument à des vibrations ou à des chocs lors de
son transport et de sa manipulation. Faites particulièrement attention à
ne pas le laisser tomber.
• Ne stockez pas et n’utilisez pas l’instrument dans un environnement
exposé à la lumière directe du soleil, à une température élevée, à une
humidité élevée ou à la condensation. L’instrument peut être déformé
ou détérioré au niveau de l’isolation, et il peut ne pas répondre aux
spécifications.
• Avant d’utiliser l’instrument, inspectez et vérifiez que le fonctionnement
ne présente pas de dysfonctionnements dus aux conditions de stockage
ou de transport. En cas de dysfonctionnement, contactez votre
revendeur ou représentant YOKOGAWA.
• Cet instrument n’est pas étanche à la poussière ou à l’eau. Ne l’utilisez
pas dans un environnement poussiéreux ou humide.
• La tête de capteur est un assemblage de précision comprenant un
composant moulé, un noyau de ferrite et un élément à effet Hall.
Manipulez cet appareil avec précaution car il peut être endommagé par
des changements brusques de température ambiante, des contraintes
mécaniques ou des chocs.
• Les surfaces correspondantes de la tête du capteur sont rectifiées avec
précision. Manipulez l’instrument avec précaution, car les rayures sur
les surfaces peuvent altérer les performances.
• Essuyez délicatement la poussière ou la saleté sur les surfaces
correspondantes de la tête du capteur avec un chiffon doux. Cela peut
générer un bruit de résonance ou altérer les performances.
• Ne pliez pas et ne tirez pas sur le câble du capteur ou le câble
d’alimentation pour éviter les dommages dus à la déconnexion.
• Les capteurs de courant peuvent être endommagés par l’électricité
statique. Veillez à ne pas appliquer d’électricité statique à l’instrument, y
compris dans les cas suivants.
• Toucher la tête du capteur avec un objet chargé d’électricité statique
• Toucher la tête du capteur avec un objet présentant une différence de
potentiel électrique
• Un utilisateur chargé d’électricité statique touchant la surface du
noyau lors du nettoyage des surfaces correspondantes de la tête du
capteur
(Lors du nettoyage des surfaces, prenez des mesures contre
l’électricité statique telles que le port d’un bracelet antistatique.)

vi IM 701930-01E
• Essuyez doucement l’instrument avec un chiffon doux humidifié avec
une petite quantité d’eau ou de détergent doux. N’utilisez pas de
détergents contenant des solvants organiques tels que le benzène,
l’alcool, l’acétone, les éthers, les cétones, les diluants ou l’essence. Ils
peuvent déformer ou décolorer l’instrument.
• Lorsque l’appareil est sous tension, maintenez la tête du capteur
fermée, sauf lors du serrage du conducteur à mesurer. Le laisser ouvert
peut endommager l’instrument.
Note
• Accurate measurement may be impossible in locations subject to strong external
magnetic fields, such as near transformers and high-current conductors, or in
locations subject to strong external electric fields, such as near radio transmission
equipment.
• Depending on the current frequency that is measured, oscillation may occur, but
this has no effect on measurements.
