Ambient temperature and humidity
Use the instrument in the following environment.
• Ambient temperature: 5
°
C to 40
°
C
However, in order to obtain highly accurate measurements, operate the instrument
in the 23
±
5
°
C temperature range.
• Ambient humidity: 20% to 80% RH
No condensation should be present. However, in order to obtain highly accurate
measurements, operate the instrument in the 50
±
10% RH range.
Note
Condensation may occur if the instrument is moved to another place where the ambient
temperature is higher, or if the temperature changes rapidly. In this case, let the instrument
adjust to the new environment for at least an hour before using it.
Do not install the instrument in the following places:
• In direct sunlight or near heat sources.
• 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.
• In an unstable location.
Storage Location
When storing the TA120E, avoid the following locations:
• A place with a relative humidity of 80% or more.
• In direct sunlight.
• A hot place with a temperature of 60
°
C or more.
• Near a high humidity or heat may source.
• Where mechanical vibration is high.
• A place with corrosive gases or flammable gases.
• A place with a lot of dust, trash, salt, or iron powder.
• A place where water, oil, or chemicals splash.
We strongly recommend you store the TA120E in an environment with a temperature
between 5
°
C and 40
°
C and a relative humidity between 20% to 80% RH.
