Do Not Remove the Case or Disassemble or Alter the Instrument

Only qualified YOKOGAWA personnel may remove the case and disassemble or alter the 
instrument.

Remove Connections When Carrying or Moving the Instrument

When carrying or moving the instrument, remove all cords (including the power cord) and cables.

 CAUTION

When Using the Same Wavelength That Is Used in Real Communication to Make 

Measurements

If communication light is present in the optical fiber that you want to measure, the communication 
may be affected. Take appropriate precautions to avoid communication interference.
In addition, to make accurate measurements with the AQ7277B, take the measurement 
environment (such as the presence of communication light) into consideration.

When Using a Wavelength (1650 mm) Different from That Used in Real Communication to 

Make Measurements

When there is communication light in the fiber under measurement, use a light beam with a 
different wavelength to make measurements.
If the device connected to the system under measurement does not have a filter for blocking 1650 
nm laser beams or depending on the lightfastness power rating or the attenuation characteristics 
of the blocking filter, the light pulses that the AQ7277B emits may damage the device. Be sure 
to install an appropriate blocking filter and check that the device’s ratings are adequate before 
making measurements.

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.

 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.

•  Utilisez une alimentation électrique secondaire isolée (LPS ou équivalent).

•  Utilisez un adaptateur secteur qui répond aux puissances AQ7277B.

•  Utilisez un adaptateur de courant alternatif avec une corde de pouvoir qui rencontre les normes 

appropriées de la région dans laquelle vous l'utilisez.

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 AQ7277B et qu'elle est compatible avec la tension nominale maximale 

du cordon d'alimentation.

Faisceau laser

Ne pas fixer directement ou indirectement le faisceau laser, ni la réflexion spéculaire du faisceau 

en l'absence d'équipement de protection. Ne pas orienter le faisceau laser en direction des yeux. 

Le faisceau laser peut entraîner la cécité ou causer des lésions oculaires.

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.
