Make sure to observe the following safety precautions to prevent electric shock, personal
injury, or damage to the instrument.
WARNING
• Use the Instrument Only for Its Intended Purpose
This instrument is a current output type current sensor with a 1500:1 current transformation
ratio that performs transformation on the primary current.
Use the instrument only for measuring current.
• Beware of electric shock.
• Do not perform measurement if the case is damaged.
• Do not operate the instrument with wet hands, in a rainy or humid environment, or if any
water droplets are visible on it.
• Condensation may appear if sudden changes in temperature occur. If this happens,
let the instrument acclimatize to the new temperatures for at least one hour, then refrain
from using the instrument until confirming that there is no condensation.
• Do not disassemble the instrument.
The instrument should be disassembled by qualified personnel only.
• Use the correct power supply.
Ensure that the source voltage matches the voltage of the power supply before turning the power ON.
• Do not use uninsulated measurement conductors or cables.
Use conductors or cables with reinforced insulation.
• Make sure that the surface temperature of measurement conductors is within the
instrument's operating temperature range.
• Although it is well-insulated, do not touch the instrument or secondary output cable while
voltage is being applied to the primary conductor.
• Connect the secondary signal output before supplying power to the instrument.
• Do not disconnect the secondary output while power is being supplied to the instrument to
prevent electric shock or damage to the instrument.
• Do not apply primary current before supplying power to the instrument to prevent electric
shock or damage to the instrument.
• Do not input excessive current as malfunction or damage may result.
• Do not allow vibrations to disturb the instrument after it has been set in place as damage
may result.

AVERTISSEMENT
•
Utiliser l’instrument aux seules fins pour lesquelles il est prévu
Cet instrument est un capteur de courant du type de débit de courant.
Utiliser l’instrument uniquement pour mesurer le courant.
• Faire attention aux chocs électriques.
• Ne pas effectuer une mesure si le boîtier est endommagé.
• Ne pas faire fonctionner le dispositif avec les mains humides, dans un environnement
pluvieux ou humide, ou si des gouttelettes d’eau sont visibles dessus.
• La condensation peut s’effectuer et les changements brusques de température se
produisent. Si cela se produit, laisser le dispositif s’acclimater aux nouvelles températures
pendant au moins une heure, puis éviter de l’utiliser jusqu’à confirmer qu’il n’y a pas de
condensation.
• Ne pas démonter le dispositif.
Le dispositif doit être démonté uniquement par un personnel qualifié.
Thank you for purchasing the AC/DC Current Sensor. To ensure correct use, please read this manual
thoroughly before beginning operation.
Please familiarize yourself with the functions and characteristics of the AC/DC current sensor prior to
operation. After reading this manual, keep it in a safe place.

• Vérifier l’alimentation.
S’assurer que la source de tension correspond à la tension de l’alimentation avant la mise
sous tension.
• Ne pas utiliser de conducteurs ou de câbles de mesure non isolés.
Utiliser des conducteurs ou des câbles avec isolation renforcée.
• S’assurer que la température de surface des conducteurs de mesure se situe dans la plage
de température de fonctionnement du dispositif.
• Bien qu’il soit bien isolé, ne pas toucher le dispositif ou le câble de sortie secondaire pendant
que la tension s’applique au conducteur primaire.
• Connecter la sortie du signal secondaire avant d’alimenter le dispositif.
• Ne pas débrancher la sortie secondaire lorsque l’alimentation électrique est fournie au
dispositif afin d’éviter tout risque de choc électrique ou d’endommagement de l’instrument.
• Ne pas appliquer de courant primaire avant d’alimenter le dispositif afin d’éviter tout risque
d’électrocution ou d’endommager l’instrument.
• Ne pas entrer de courant excessif, car un dysfonctionnement ou des dommages peuvent en résulter.
• Ne pas laisser les vibrations perturber le dispositif après qu’il a été mis en place, car des
dommages peuvent en résulter.

WARNING
Do not apply primary current before supplying power to the instrument to prevent electric
shock or damage to the instrument.
CAUTION
Ensure that the current flowing to the primary conductor of the object to be measured is
within the measuring range (current rating).
If the current exceeds the measuring range, the instrument may overheat and get damaged.

AVERTISSEMENT
Ne pas appliquer de courant primaire avant d’alimenter le dispositif afin d’éviter tout risque
d’électrocution ou d’endommager l’instrument.
ATTENTION
S’assurer que le courant qui s’achemine vers le conducteur primaire de l’objet à mesurer se
situe dans la plage de mesure (courant nominal). Si le courant dépasse la plage de mesure,
le dispositif peut surchauffer et subir des dommages.
1.
Connect the secondary connector on the instrument to the current input terminal on the
measuring instrument, and connect to 0 V (common) and ±15 V on the power supply.
2.
Set up the measuring instrument and power supply to match the specifications of the current
transducer. Carefully read the user’s manuals for your measuring instrument and power supply
to perform the correct procedure for making the connections.
