Safety Precautions
This product is designed to be used by a person with specialized knowledge.
This instrument is an IEC safety class I instrument (provided with a terminal for protective earth
grounding).
The general safety precautions described herein must be observed during all phases of operation.
If the instrument is used in a manner not specified in this manual, the protection provided by the
instrument may be impaired.
This manual is part of the product and contains important information. Store this manual in a safe place
close to the instrument so that you can refer to it immediately. Keep this manual until you dispose of
the instrument.
YOKOGAWA assumes no liability for the customer’s failure to comply with these requirements.
The following symbols are used on this instrument.
Warning: handle with care. Refer to the user’s manual or service manual. This symbol appears
on dangerous locations on the instrument which require special instructions for proper handling
or use. The same symbol appears in the corresponding place in the manual to identify those
instructions.

IM DLM4038-03EN
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
Before connecting the power cord, ensure that the source voltage matches the rated supply
voltage of the DLM4000 and that it is within the maximum rated voltage of the provided 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 supplied by
YOKOGAWA. 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. Additionally, do not use the power cord supplied with this instrument with another
instrument.
Connect the Protective Grounding Terminal
Make sure to connect the protective earth to prevent electric shock before turning on the
power. The power cord that comes with the instrument is a three-prong type power 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 gasses 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.
Ground the Instrument before Making External Connections
Securely connect the protective grounding before connecting to the item under measurement
or to an external control unit. Before touching a circuit, turn off its power and check that it has
no voltage. To prevent the possibility of electric shock or an accident, connect the ground of
the probe and input connector to the ground of the item being measured.
Safety Precautions

xIM DLM4038-03EN
Measurement Category
The measurement category of the DLM4000 signal input terminals is Other (O). Do not use it

residential area may cause radio interference in which case the user will be required to correct
the interference.
French
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
Avant de brancher le cordon d’alimentation, vérifier que la tension source correspond à
la tension d’alimentation nominale du DLM4000 et qu’elle est compatible avec la tension
nominale maximale du cordon d’alimentation.
Utiliser le cordon d’alimentation et la fiche adaptés
Pour éviter les risques de choc électrique ou d’incendie, utilisez le cordon d’alimentation fourni
par YOKOGAWA. La fiche doit être branchée sur une prise secteur raccordée à la terre. En
cas d’utilisation d’une rallonge, celle-ci doit être impérativement reliée à la terre. Par ailleurs,
n’utilisez pas le cordon d’alimentation fourni pour cet instrument avec un autre appareil.
Brancher la prise de terre
Avant de mettre l’instrument sous tension, penser à brancher la prise de terre pour éviter tout
choc électrique. Le cordon d’alimentation livré avec l’instrument est doté de trois broches.
Brancher le cordon d’alimentation sur une prise de courant à trois plots et mise à la terre.
Safety Precautions

xi
IM DLM4038-03EN
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 ou de vapeurs 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.
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 tout risque de choc électrique, brancher la terre de la sonde
et du connecteur d’entrée sur la terre de l’appareil à mesurer.
Catégorie de mesure
La catégorie de mesure des terminaux d’entrée de signal du DLM4000 est Autre (O). Ne pas
l’utiliser pour mesurer l’alimentation électrique, ni pour les catégories de mesure II, III et IV.
Installer et utiliser l’instrument aux emplacements appropriés
• Ne pas installer, ni utiliser l’instrument à l’extérieur ou dans des lieux exposés à la pluie ou
à l’eau.
• Installer l’instrument de manière à pourvoir immédiatement le débrancher du secteur en
cas de fonctionnement anormal ou dangereux.
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
accessoires.
Ne pas utiliser d’accessoires défectueux.
ATTENTION
Limitations relatives à l’environnement opérationnel
Ce produit est un produit de classe A (pour environnements industriels). L’utilisation de ce
produit dans un zone résidentielle peut entraîner une interférence radio que l’utilisateur sera
tenu de rectifier.
