instrument side of the converter.
Electric shock hazard
Be sure to check that no electric power is supplied before starting the procedure.
Electric shock hazard
Be sure to ground the grounding terminal (The ground resistance should be 100 or less).
To connect any load exceeding the contact capacity or any induction load (e.g., motor, pump), be sure
to use a power relay.
Unexpected operation of the unit may result in damage to the unit or an injury. Be sure to turn OFF the
power when replacing any parts.

Product Handling Information
Operational precautions
Use of the product in a manner not specified by the manufacturer may impair the protection
provided by the product. And it may also reduce product performance.
Exercise the following precautions:
Do not press any operation key with the tip of your nail or anything pointed.
Do not use solutions such as organic solvents.
Do not operate the automatic cleaner while the inside of the detector is filled with water
and the valve is closed. Doing so may damage the cleaner.
The operation of this equipment at any voltage outside the rated range may cause
damage. It is recommended that the fluctuations in power supply voltage fall within a
range of 10.
Take care about the load connecting to the normally closed relay contacts of the R1 and
R2 which are closed when power is turned OFF.
If a corrosive gas is present in the installation environment, supply clean instrument air
from the purge air supply inlet of the equipment.
Replace the desiccant with a new one periodically. In particular, when measuring cold
water, measurement cannot be performed correctly if dew condensation occurs.
