Environmental Conditions
This instrument is intended to be used in an indoor pollution degree 2 environment. The operating
temperature range is 0
∘
C to 40
∘
C and 20% to 80% relative humidity, with no condensation allowed.
Measurements made by this instrument may be outside specications if the instrument is used in non-
oce-type environments. Such environments may include rapid temperature or humidity changes, sunlight,
vibration and/or mechanical shocks, acoustic noise, electrical noise, strong electric elds, or strong
magnetic elds.
Do not operate the instrument in the presence of ammable gases or
vapors, fumes, or nely-divided particulates.
The instrument is designed to be used in oce-type indoor
environments. Do not operate the instrument
• In the presence of noxious, corrosive, or ammable fumes,
gases, vapors, chemicals, or nely-divided particulates.
• In relative humidity conditions outside the instrument’s
specications.
• In environments where there is a danger of any liquid being
spilled on the instrument or where any liquid can condense on
the instrument.
• In air temperatures exceeding the specied operating temperatures.
• In atmospheric pressures outside the specied altitude limits or
where the surrounding gas is not air.
• In environments with restricted cooling air ow, even if the air
temperatures are within specications.
• In direct sunlight.
