you can refer to it immediately. Keep this manual until you dispose of the instrument.
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 calibrator for the voltage/current measuring instrument (CA310), thermocouple/measuring
instrument (CA320), and RTD/measuring instrument (CA330). Use this instrument only as a calibrator.
Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
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 meter which require
special instructions for proper handling or use. The same symbol appears in
the corresponding place in the manual to identify those instructions.

AC adapter
Only use the dedicated AC adapter for the instrument.
Batteries
• Do not mix new and old batteries or mix different brands or types of batteries. The batteries may leak, heat up, or
burst due to their characteristic differences.
• Never replace the batteries while measurement is in progress.
Do Not Operate in an Explosive Atmosphere
Do not use this instrument in the presence of flammable gases or vapors. Doing so is extremely dangerous.
Do Not Remove Covers or Disassemble or Alter the Instrument
Only qualified YOKOGAWA personnel may remove the covers and disassemble or alter the instrument.
Measurement Category
The measurement category of this instrument’s signal input terminals is Other (O). Do not use it to measure the main
power supply or for Measurement Categories II, III, and IV.
Install or Use the Instrument in Appropriate Locations
• Do not install the instrument outdoors or in locations subject to rain or water. Or, use the instrument in such locations.
• Install the instrument so that you can immediately turn off the power if an abnormal or dangerous condition occurs.
Wiring
• Be sure to use the included lead cables.
• The maximum voltage application between all I/O terminals and earth is 50 VDC (measurement terminal of CA310)
or 42 VDC (other than the measurement terminal of CA310). Do not apply voltages that exceed 50 VDC or 42 VDC .
Doing so may cause electric shock or burns or may damage the instrument.
• Always turn off the power of the device under measurement before connecting it. Connecting or disconnecting lead
cables without turning off the device under measurement is extremely dangerous.
• Do not connect current circuits to the CA310 voltage input terminal. Likewise, do not connect voltage circuits to the
current input terminal. Improper connection may cause electric shock or burns or may damage the device under
measurement or the instrument.
• Do not apply currents that exceed the maximum allowable input current to the CA310 current input terminal.

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 will be required to correct the interference.
French
AVERTISSEMENT
Ne faites de cet équipement que l’utilisation pour laquelle il a été conçu
Cet équipement est un calibreur pour l’équipement de mesure de tension/courant (CA310), pour l’équipement de
termocouple/mesure (CA320) et pour l’équipement de RTD/mesure (CA330). Utilisez cet équipement à des fins de
calibrage uniquement.
Inspecter l’apparence physique
Ne pas utiliser l’instrument si son intégrité physique semble être compromise.
Adaptateur c.a.
Utiliser exclusivement l’adaptateur c.a. dédié pour l’instrument.
Batteries
• Ne pas mélanger des batteries neuves et des batteries usagées, ni des batteries de marques ou de types différents.
Les batteries risquent de fuir, de chauffer ou d’éclater en raison de leurs différentes caractéristiques.
• Ne jamais remplacer les batteries lorsque la mesure est en cours.
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.

Catégorie de mesure
La catégorie de mesure des terminaux d’entrée de signal du CA310, CA320, CA330 est Autre(O). Ne pas l’utiliser pour
mesurer l’alimentation électrique, ni pour les catégories de mesureII, 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.
Câblage
• Veillez à utiliser tous les câbles fournis.
• La tension maximum autorisée entre toutes les bornes I/O et la terre est de 50 V c.c. (borne mesure du CA310) ou
de 42 V c.c. (autre que la borne de mesure du CA310). N’appliquez pas de tension supérieure à 50 V c.c (CA310) ou
à 42 V c.c (CA320/CA330). Le cas échéant vous vous exposeriez à des risques de choc électrique ou de brûlure ou
vous risqueriez d’endommager l’équipement.
• Mettez toujours le dispositif à mesurer hors tension avant de le connecter à l’équipement. Il est extrêmement
dangereux de brancher ou débrancher des câbles sans avoir préalablement mis le dispositif à mesurer hors tension.
• Ne branchez pas de circuits de courant sur la borne d’entrée de tension du CA310. Ne branchez pas non plus de
circuits sous tension sur la borne d’entrée de courant. Un branchement incorrect vous exposerait à des risques de
choc électrique ou de brûlure, ou risquerait d’endommager l’appareil à mesurer ou l’équipement.
• N’appliquez pas de courant supérieur au courant d’entrée maximum admissible à la borne d’entrée de courant du
CA310.

Handling Precautions
Safety Precautions
If you are using this instrument for the first time, make sure to thoroughly read “Safety Precautions,” on pages 7 to 10.
Unplug If Abnormal Behavior Occurs
If you notice smoke or unusual odors coming from the instrument, immediately turn off the power, remove the batteries if possible, and
contact your nearest YOKOGAWA dealer.
General Handling Precautions
Do Not Place Objects on Top of the Instrument
Never place objects such as other instruments or objects that contain water on top of the instrument. Doing so may damage the
instrument.
Do Not Subject the Inputs and Outputs to Mechanical Shock
If the I/O connectors or adapters are subjected to mechanical shock, they may be damaged. The instrument may not perform
measurements correctly due to damage or deformation that is not visible to the naked eye.
Do Not Scratch the LCD
Because the LCD can be easily scratched, do not allow any sharp objects near it. Also, do not apply vibration or shock to it. Furthermore,
do not apply strong shock to the LCD or place objects on top of it.
Remove the Batteries during Extended Non-Use
Remove the batteries from the main unit. Remove the AC adapter power cord from the outlet.
When Carrying the Instrument
Remove the power cord and connecting cables.
When Cleaning the Instrument
When cleaning the case or the operation panel, gently wipe the outer surface using a damp, well-wrung, soft, clean cloth. The instrument
can malfunction if water enters inside the instrument.
Do not use chemicals such as benzene or thinner. Doing so may cause discoloring and deformation.

IM CA310-02EN 19
Other Precautions
• Keep electrically charged objects away from the input terminals. They may damage the internal circuitry.
• Do not cover the case or operation panel with a volatile material or leave rubber or vinyl products in contact with the case or operation
panel for a long time.
Storage Precautions
Avoid the following kinds of places for storing the instrument:
• Where the temperature falls outside the storage temperature and humidity ranges
• In direct sunlight or near heat sources
• In an environment with excessive amounts of soot, steam, dust, or corrosive gas
• In an environment subject to large levels of mechanical vibration
• On an unstable surface
• Where an excessive amount of soot, dust, salt, or iron is present
