Safety Precautions
1
Please read the instruction manual carefully for correct use.
The speci cation and dimensions provided in the instruction
manual is subject to change without notice for product performance.
Warning!
1. The product is not manufactured as a safety device; therefore, dual
safety devices are required if the product is used as controlling
devices or cases with concern of casualties or serious damage to
the peripheral and signi cant property damage.
2. Do not perform wiring, inspection, and maintenance while power
connected.
3. Terminal numbers must be checked when connecting power.
4. The equipment must not be disassembled, processed, improved, or
repaired.
Caution!
• Please understand how to use, safety regulations, or warnings before the
equipment is installed. The equipment must be used within the provisions
and capacity provided in the manual.
• Do not perform wiring and installation in motors with large inductive load
and solenoid.
• Use the same line when extending sensors and do not use excessive length.
• Do not use parts that create an arc when switching nearby or the same power.
• The power line should be away from high-tension power cables and avoid
installation in areas with high moisture, oil, and dust.
• Avoid installation in direct sunlight and areas exposed to rain.
• Avoid installation in areas with high magnetic, noise, vibration, and impact.
• The equipment should be installed su ciently distant from strong alkali and
strong acid substances.
• When the equipment is installed in the kitchen, do not spray water directly
onto the equipment for cleaning.
• Do not install in places with high temperature/humidity that exceed the rate.
• Care should be provided not to disconnect sensor cables or cause damage.
• Sensor cables require signi cant distance from signal line, power, motive power,
and load line and use independent pipes.
• No warranty service shall be provided if the product has been altered or tampered
with.
• The mark on the wiring terminals is safety statement, such as warning or caution.
• Do not use the product near machines that generate strong high-frequency noise
(high frequency welding machine, high-frequency sewing machine, high-frequency
radios, large SCR controller).
• The product may cause injury or property damage if used for purposes not intended
by the manufacturer.
• Do not leave the product within reach of children as the equipment is not a toy.
• Installation must be performed by professionals or quali ed individual.
• The company shall not be held responsible for any damage caused by negligence of
consumers or due to non-conforming of the warnings or caution statements
aforementioned.
Danger!
Caution, risk of electric shock
Electric shock– Do not contact with AC terminal during current carrying. This may
cause electric shock.
Input power must be blocked when checking input power.

1 humidity calibration
.
The displayed value can be set to the actual measured humidity when the current
humidity display value and the humidity measured by using a precision instrument
di er.
Example 1) Display value: 5%, the actual measured humidity: 10% => COR +5% input
Example 2) Display value: 5%, the actual measured humidity temperature: 2% => COR -3% input
Humidity sensor heating function
2
.
Dew forms around the sensor devices if humidity is extremely high; hence, the function generates
heat inside the sensor to prevent dew formation if the current humidity is 95% or more.
The heating function operates automatically in 95％ or more humidity and the function
is disabled when humidity level is below 95％.
The automatic heating function is not used.
Caution 1. When the humidity sensor heating function is in operation, the current temperature
of the display window may increase slightly.

. . Humidity setting for 20 mA current output at PV transmit output
.
Humidity setting for 4mA current output at PV transmit output
It is for sending the current humidity to the current output. The humidity range set in H.20 and
H.4 is divided equally and output to 4 - 20mA current.
E.g) .
current 0% 25% 50%

Temperature calibration
The displayed value can be set to the actual measured temperature when the current
temperature display value and the temperature measured by using a precision instrument di er.
Example 1) Display value: 5.0℃, the actual measured temperature: 10.0℃ => COR +5.0℃ input
Example 2) Display value: 5.0℃, the actual measured temperature: 2.0℃ => COR -3.0℃ input
