Well-Ventilated Location
There are inlet holes on the bottom side of the instrument. There are also vent holes for the cooling
fan on the left side panel and the top panel. To prevent internal overheating, allow for enough space
around the instrument (see the figure below) and do not block the inlet and exhaust holes.

When connecting cables and opening and closing the cover of the built-in printer, provide extra
operating space in addition to the space in the figure shown above.
Ambient Temperature and Humidity
Ambient temperature: 5 to 40°C
Ambient humidity: 20 to 80% RH (when the printer is not used; no condensation)
35 to 80% RH (when the printer is used)
Note
• To ensure high measurement accuracy, operate the instrument in the 23 ±5°C temperature range and 20
to 80% RH.
• Condensation may occur if the instrument is moved to another place where the ambient temperature
is higher, or if the temperature changes rapidly. In such cases, allow the instrument adjust to the new
environment for at least an hour before using the instrument.
Do not install the instrument in the following places.
• Outdoors.
• In direct sunlight or near heat sources.
• Where the instrument is exposed to water or other liquids.
• Where an excessive amount of soot, steam, dust, or corrosive gas is 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.
