3.2 Installing the Instrument
Installation Location and Environment
3-4
The instrument must be installed where the following conditions are met.
Orientation and Stability
Install the instrument in a stable, horizontal place. Accurate measurements may be
hindered if the instrument is used in an unstable place or tilted position.
Ventilation
Inlet holes are located on the top and bottom of the instrument. In addition, there are
vent holes for the cooling fan on the rear panel. To prevent internal overheating, allow for
enough space around the instrument (see the figure below) and do not block the vent
holes.

Ambient Temperature and Humidity
Use the instrument in the following environment.
• Ambient temperature: 5 to 40°C
However, in order to obtain highly accurate measurements, operate the instrument in
the 23 ±5°C temperature range.
• Ambient humidity: 20% to 80% RH
No condensation should be present. However, in order to obtain highly accurate
measurements, operate the instrument in the 50 ±10% RH range.
Note
Condensation may occur if the instrument is moved to another place where the ambient
temperature is higher, or if the temperature changes rapidly. In this case, let the instrument
adjust to the new environment for at least an hour before using it.
Do Not Install the Instrument in Any of the Following Places
• In direct sunlight or near heat sources
• Where an excessive amount of soot, steam, dust, or corrosive gases are present
• Near strong magnetic field sources
• Near high voltage equipment or power lines
• Where the level of mechanical vibration is high
• On an unstable surface
