2.2 Appropriate Locations for Using the Instrument
Well-Ventilated Location
There are inlet holes on the right side panel of the instrument. There are also vent holes for the
cooling fan on the left side 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, allow for enough space, above and beyond the space shown in the figure
above, to carry out the procedure.
Ambient Temperature and Humidity
Ambient temperature: 0°C to 45°C
Ambient humidity: 20%RH to 85%RH
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 or
humidity 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
