IM AQ6380-02EN
Failure to comply with the precautions below could lead to injury
or death or damage to the instrument.
WARNING
Use the Instrument Only for Its Intended Purpose
This instrument is a waveform measuring device that monitors and measures electrical
signals. Do not use this instrument for anything other than as a waveform measuring device.
Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
Use the Correct Power supply
First, ensure that the source voltage matches the rated supply voltage of the instrument and
that it is within the maximum rated voltage of the power cord you will use. Then connect the
power cord.
Use the Correct Power Cord and Plug
To prevent the possibility of electric shock or fire, be sure to use the power cord for the
instrument. The main power plug must be plugged into an outlet with a protective earth
terminal. Do not invalidate this protection by using an extension cord without protective earth
grounding. Further, do not use this power cord with other instruments.
Connect the Protective Ground Terminal
Be sure to connect the protective earth to prevent electric shock before turning ON the power.
The power cord that you can use for the instrument is a three-prong cord. Connect the power
cord to a properly grounded three-prong outlet.
Do Not Impair the Protective Grounding
Never cut off the internal or external protective earth wire or disconnect the wiring of the
protective earth terminal. Doing so may result in electric shock or damage to the instrument.
Do Not Use When the Protection Functions Are Defective
Before using this instrument, check that the protection functions, such as the protective
grounding and fuse, are working properly. If you suspect a defect, do not use the instrument.
Do Not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable gases or vapors. Doing so is
extremely dangerous.
Do Not Remove the Covers or Disassemble or Alter the Instrument
Only qualified YOKOGAWA personnel may remove the covers and disassemble or alter the
instrument. The inside of the instrument is dangerous because parts of it have high voltages.
Accessories
Use the accessories specified in this manual. Moreover, use the accessories of this product
only with Yokogawa products that specify them as accessories. Do not use faulty accessories.
Safety Precautions

viii IM AQ6380-02EN
Install or Use the Instrument in Appropriate Locations
• Do not install or use the instrument outdoors or in locations subject to rain or water.
• Install the instrument so that you can immediately remove the power cord if an abnormal or
dangerous condition occurs.
Manual CD
Never play this manual CD, which contains the user’s manuals, in an audio CD player.
Doing so may cause loss of hearing or speaker damage due to the large sounds that may be
produced.
CAUTION
Operating Environment Limitations
This product is classified as Class A (for use in industrial environments). Operation of this
product in a residential area may cause radio interference, in which case the user will be
required to correct the interference.

AVERTISSEMENT
Utiliser l’instrument aux seules fins pour lesquelles il est prévu
Cet instrument est un appareil de mesure de forme d’onde pour le contrôle et la mesure des
signaux électriques. Ne pas utiliser cet instrument à d’autres fins que celles de mesure de
forme d’onde.
Inspecter l’apparence physique
Ne pas utiliser l’instrument si son intégrité physique semble être compromise.
Vérifier l’alimentation
Assurez-vous que la tension d’alimentation correspond à la tension d’alimentation nominale
de l’appareil et qu’elle ne dépasse pas la plage de tension maximale du cordon d’alimentation
à utiliser.
Utiliser le cordon d’alimentation et la fiche adaptés
Pour éviter tout risque de choc électrique, utiliser exclusivement le cordon d’alimentation
prévu pour cet instrument. La fiche doit être branchée sur une prise secteur raccordée à la
terre. En cas d’utilisation d’une rallonge, celleci doit être impérativement reliée à la terre. Par
ailleurs, ne pas utiliser ce cordon d’alimentation avec d’autres instruments.
Brancher la prise de terre
Avant de mettre sous tension, veiller à brancher la mise à la terre de protection afin d’éviter
les chocs électriques. Le cordon d’alimentation que vous utilisez pour l’instrument est un
cordon à trois broches.
Brancher le cordon d’alimentation sur une prise de courant à trois plots et mise à la terre.
Ne pas entraver la mise à la terre de protection
Ne jamais neutraliser le fil de terre interne ou externe, ni débrancher la borne de mise à la
terre. Cela pourrait entraîner un choc électrique ou endommager l’instrument.
Ne pas utiliser lorsque les fonctions de protection sont défectueuses
Avant d’utiliser l’instrument, vérifier que les fonctions de protection, telles que le raccordement
à la terre et le fusible, fonctionnent correctement. En cas de dysfonctionnement possible, ne
pas utiliser l’instrument.
Ne pas utiliser dans un environnement explosif
Ne pas utiliser l’instrument en présence de gaz et de vapeur inflammables. Cela pourrait être
extrêmement dangereux.
Ne pas retirer le capot, ni démonter ou modifier l’instrument
Seul le personnel YOKOGAWA qualifié est habilité à retirer le capot et à démonter ou modifier
l’instrument. Certains composants à l’intérieur de l’instrument sont à haute tension et par
conséquent, représentent un danger.
Safety Precautions

xIM AQ6380-02EN
Relier l’instrument à la terre avant de le brancher sur des connexions externes
Toujours relier l’instrument à la terre avant de le brancher aux appareils à mesurer ou à une
commande externe. Avant de toucher un circuit, mettre l’instrument hors tension et vérifier
l’absence de tension. Pour éviter un choc électrique et un accident, connecter la terre des
sondes ou les connecteurs d’entrée au potentiel de terre de l’appareil faisant l’objet de la
mesure. La terre de chaque borne d’entrée du signal (connecteur d’entrée) de cet instrument
est commune à la terre de protection de l’instrument (voir le schéma fonctionnel à l’annexe 3).
Ne pas appliquer de signaux de potentiel flottant à la terre du connecteur d’entrée. Ceci est
extrêmement dangereux car le potentiel de terre risque d’être court-circuité.
Catégorie de mesure
La catégorie de mesure des bornes d’entrée du signal de cet instrument est Autre (O). Ne pas
l’utiliser pour mesurer l’alimentation électrique, ni pour les catégories de mesure II, III et IV.
Accessoires
Utiliser les accessoires spécifiés dans ce manuel. En outre, utiliser les accessoires de ce
produit uniquement avec des produits Yokogawa pour lesquels ils sont spécifiés comme
