supply voltage specified for the product matches the local line voltage.
● Environments containing inflammable substances.
To prevent the risk of fire and/or explosion, do not use the product in
environments containing inflammable gas, vapor, or dust.
● In the event of problems.
If abnormalities such as smoke, abnormal odor, or abnormal noise occur,
immediately turn off the power, disconnect the power cable from the main
unit, and stop using it. Also, do not install the instrument on or near
flammable materials to prevent a fire when an abnormality occurs.
● Connecting and disconnecting adapter
Before connecting/disconnecting adapter, turn off the power to the
instrument and connected devices and ground the GND terminal. Failure to
do so may cause an electric shock, performance degradation, or
malfunctions.
● Connecting and disconnecting cables
Before connecting/disconnecting cables, turn off the power to the
instrument and connected devices. Failure to do so may cause an electric
shock, performance degradation, or malfunctions.
● Concomitant use of conservation measures
If there is a possibility that a secondary disaster may occur in the system
due to a failure of the instrument, be sure to use another technical
conservation measure.
● Do not disassemble or modify the product.
Failure to observe this precaution can result in electric shock or
malfunctions. Attempting to disassemble or modify the product will
invalidate the warranty.
WARNING
●Handling of batteries
 If use primary batteries, do not recharge the primary batteries.
 If use secondary batteries, If use secondary batteries, charge the battery
with the charger specified for the battery to be used.
 Connect positive (+) and negative (-) terminals of the batteries correctly.
It may cause Liquid leakage, fever, ignite or explosion.
 Do not heat the batteries or throw the batteries into fire. It may cause
Liquid leakage, fever, ignite or explosion.
 Do not short-circuit positive (+) and negative (-) terminals of the batteries.
It may cause fever or ignite due to a rush current.
 If connecting batteries in parallel, use diodes or other means to prevent
the batteries from being inadvertently charged.
 Using the batteries at temperatures outside of the manufacturer's
specified range, may lower the performance and/or the life and cause
liquid leakage, fever, or explosion.

● Avoid installing sensors near a welding machine or performing
measurements near a welding machine.
Failure to observe this precaution may result in output abnormalities, erratic
operations, or malfunctions.
●When using or storing in an environment exposed to dust or corrosive
gas, protect the opening with a connector cap.
It may cause performance degradation or malfunctions. If dust gets inside,
performance decreases. Make sure that dust does not enter during use as
well as during storage.
● If the product is used or stored in a place near the sea, take appropriate
measures to protect the product from exposure to outside air.
Failure to observe this precaution may result in performance degradation or
malfunctions.
CAUTION

degradation, or failure.
This product is designed to be used under pressure of the standard
atmosphere.
● After power is turned OFF, wait at least 5 seconds before turning ON
power once again.
If power is turned on again within 5 seconds or if the power is repeatedly
turned ON and OFF, the product may cause performance deterioration or
failure due to the inrush current generated by the product being turned on.
● Allow the product to warm up before use.
After the power ON, always preheat the product for approximately 1 hour.
● Do not pull on or apply excessive tension to the cables.
Lay the cables with a certain safety margin of length to avoid subjecting the
connections to excessive force. Applying excessive tension to a cable may
