55 ± 10%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, before you use the instrument,
allow it to adjust to the surrounding temperature for at least an hour.
Do Not Install the Instrument in the Following Places.
• In direct sunlight or near heat sources
• In an environment with excessive amounts of soot, steam, dust, or corrosive gas
