Safety Precautions
This product is designed to be used by a person with specialized knowledge.
This instrument is an IEC protection class I instrument (provided with 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 an essential part of the product; keep it in a safe place for future
reference. YOKOGAWA assumes no liability for the customer’s failure to comply with
these requirements.
The following symbols are used on this instrument.

Safety Precautions
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
The optical measuring instrument is designed to measure the optical characteristics
of light sources and evaluate their performance. Do not use this instrument for
anything other than as an optical measuring instrument.
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 instrument 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 disable this protection by using an extension
cord without protective earth grounding.
Also, do not use the power cord that came with the instrument on any other device.
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 poses a potential shock hazerd.
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.
Reference light source output light (when the built-in light source
specification is -L1)
The instrument has a built-in reference light source for wavelength calibration, and
infrared light is always being output from the optical output connector. Never look
into the optical output connector. Infrared light entering the eyes can cause severe
injury and loss of vision.
Do not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable liquids or vapors.
Operation in such environments constitutes a safety hazard.
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.
Opening the cover is dangerous, because some areas inside the instrument have
high voltages.

Installation Location
• This instrument is designed to be used indoors. Do not install or use it outdoors.
• Install the instrument so that you can immediately remove the power cord if an
abnormal or dangerous condition occurs.
CAUTION
Operating Environment Limitations
This product is a Class A (for industrial environment) product. Operation of this
product in a residential area may cause radio interference in which case the user is
required to correct the interference.
French
AVERTISSEMENT
Utiliser l’instrument aux seules fins prévues
Cet instrument de mesure optique est prévu pour mesurer les caractéristiques
optiques des sources lumineuses et évaluer leur performance. Ne pas utiliser cet
instrument à d’autres fins que celles de mesure optique.
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 AQ6370D 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 tout risque de choc électrique ou d’incendie, toujours utiliser 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. Ne pas utiliser le cordon d’alimentation fourni avec
l’instrument pour tout 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.
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.

Source de lumière de référence
Cet instrument dispose d’une source de lumière de référence intégrée pour les
ajustements d’alignement. La lumière infrarouge est toujours émise depuis le
connecteur de sortie optique. Ne regardez jamais directement dans le connecteur
de sortie optique. La lumière infrarouge risquerait de gravement vous blesser ou de
provoquer une perte de vision.
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.
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.
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.
