IM CA150E
Operating Environment
Use the instrument in locations that meet the following conditions:
• Ambient temperature and humidity
Ambient temperature: 0 to 40°C
Ambient humidity: 20 to 80% RH (no condensation)
• Indoors
Do not use the instrument in the following locations:
• Outdoors
• In direct sunlight or near heat sources
• Where the instrument is exposed to water or other liquids
• Where there is a lot of mechanical vibration
• Near noise sources such as high-voltage equipment or power lines
• Near strong magnetic field sources
• Where an excessive amount of greasy fumes, steam, dust, or corrosive
gases are present
• In an unstable place
• Where, for example, fire and explosions caused by inflammable gases and
the like are possible
NOTE
• When you require high source and measurement accuracy,
use the instrument under the following conditions:
Ambient temperature: 23
±
5°C
Ambient humidity:
20 to 80% RH (no condensation)
When using the instrument in an ambient temperature range of 0 to 18°C or
28 to 40°C, add the temperature coefficient specified in “11. Specifications”
to the accuracy.
• When using the instrument in ambient humidity of 30% or less,
use an anti-static mat to prevent static electricity.
• Condensation may occur if the instrument is moved from a location of
low temperature and humidity to a location of high temperature and humidity,
or if the temperature otherwise changes suddenly. In such a case,
leave the instrument for at least one hour to ensure it is free from
condensation before starting operation.
