12.1 Installation Location
Install the FX indoors in an environment that meets the following conditions:
• Instrumentation Panel
The FX is designed to be installed in an instrumentation panel.
• Well-Ventilated Location
To prevent overheating, install the FX in a well-ventilated location. For the panel cut
dimensions when arranging multiple FXs, see section 12.3. When other instruments
are installed next to the FX, follow the panel cut dimensions to provide adequate
space around the FX.
• Minimal Mechanical Vibrations
Install the FX in a location that has minimal mechanical vibrations. Installing the FX in
a location that is subject to large levels of mechanical vibration will not only put added
stress on its components, it may also impede ordinary measurement.
• Level Location
Install the FX in a level location so that it is not slanted to the left or the right (however,
the FX can be inclined up to 30 degrees backward for panel mounting).
Note
Condensation may form when moving the FX from an environment whose temperature or
humidity is low to an environment whose temperature or humidity is high, or when there
is a sudden change in temperature. Temperature or humidity changes may also result in
thermocouple measurement errors. In these kinds of circumstances, let the FX adjust to the
new environment for at least an hour before using it.
Do not install the FX in the following places.
• Outdoors
• In Direct Sunlight or Near Heat Sources
Install the FX in a place that is near room temperature (23°C) and that is not subject to
large temperature fluctuations. Placing the FX in direct sunlight or near heat sources
can cause adverse effects on the internal circuitry.
• Where an Excessive Amount of Soot, Steam, Moisture, Dust, or Corrosive Gases
Are Present
Soot, steam, moisture, dust, and corrosive gases will adversely affect the FX. Avoid
installing the FX in such locations.
• Near Strong Magnetic Field Sources
Do not bring magnets or instruments that produce electromagnetic fields close to the
FX. Operating the FX near strong magnetic fields can cause measurement errors.
• Where the Display Is Difficult to See
The FX uses an LCD screen, so it is difficult to view the display from an extreme
angle. Install the FX so that the user can view the display directly from the front.
