Notes on Use
Be sure to read all of the following notes before attempting to use the WR300 Series Thermal Arraycorder.
1. Note on the CE Marking
The WR300 Series complies with the EN61326 (1997+A1:1998+A2:2001 Class A) standard based on the

2. Warning
This is a Class A product according to the EMC directive.
In a domestic environment, this product may cause radio interference or may be affected by radio
interference to the extent that proper measurement cannot be performed.
3. Notes for Safe Operation
(1) Be sure to use the Graphtec-supplied AC power cable. In environments where there is a lot of noise or
where the power supply is unstable, we recommend that you ground the WR300 Series.
(2) When a high-voltage signal cable has been connected to the main unit's analog signal input terminal,
avoid touching the leads of the input terminal's signal cable to prevent electrical shock due to high
voltage.
(3) Ensure that the WR300 Series power source is positioned so that it can easily be disconnected.
4. Notes on Functions and Performance
(1) Be sure to connect the main unit to an AC or DC power supply that conforms to the rated range.
Connection to a non-rated power supply may cause the main unit to overheat and break down.
(2) Do not block the vent on the main unit.
Continued operation with the vent blocked may cause the main unit to overheat and break down.
(3) To avoid malfunctions and other damage, avoid using the WR300 Series in the following locations.
• Places exposed to high temperature and/or high humidity, such as in direct sunlight or near heating
equipment. (Operating range - Temperature: 0 to 40°C, Humidity: 30 to 80% RH)
• Locations subject to excessive salt spray or heavy fumes from corrosive gas or solvents.
•Excessively dusty locations.
• Locations subject to strong vibrations or shock.
• Locations subject to surge voltages and/or electromagnetic interference.
(4) Use the chart paper supplied by Graphtec. The print quality cannot be guaranteed if other paper types
are used.
(5) If the main unit becomes soiled, wipe it off using a soft, dry cloth. Use of organic solvents (such as
thinner or benzene) causes deterioration and discoloration of the outer casing.
