3.2 Installing the Instrument
Installation condition
Install the instrument in a place that meets the following conditions.
Flat, even surface
Install the instrument on a stable horizontal surface. Otherwise, precise measurements
may be impeded.
Ambient temperature and humidity
Ambient temperature: 5 to 40
°
C
Ambient humidity:
20 to 80%RH (no condensation)
Do not install the instrument in the following places:
• Outdoor.
• In direct sunlight or near heat sources.
• Where an excessive amount of soot, steam, dust, or corrosive gases are present.
• Where the instrument is exposed to water or other liquids.
• Near strong magnetic field sources.
• Near high voltage equipment or power lines.
• Where the level of mechanical vibration is high.
• In an unstable place.
• In a place where the power switch cannot be accessed easily.
Note
• For the most accurate measurements, use the instrument in the following environment.
Ambient temperature: 23
±
3
°
C, ambient humidity: 30 to 75%RH (no condensation)
When using the instrument in a place where the ambient temperature is 5 to 18
°
C or 28 to
40
°
C, add the temperature coefficient to the accuracy of the module as specified in chapter
12, “Specifications.”
• When installing the instrument in a place where the ambient humidity is 30% or below, take
measures to prevent static electricity such as using an anti-static mat.
• Internal condensation may occur if the instrument is moved to another place where both the
ambient temperature and humidity are higher, or if the temperature changes rapidly. In this
case, let the instrument adjust to the new environment for at least one hour before using the
instrument. Check to see that there is no condensation.
Installation position
Place the instrument on a flat, even surface as shown in the figure below. To adjust the
handle position, pull the handle outward on each side along the axis of rotation by 2 to 3
mm, then slowly rotate the handle to another locked position.

Storage Location
Do not store the instrument in the following kinds of places:
• Where the relative humidity is 80% or higher or where the temperature is 60
°
C or
higher
• In direct sunlight or near heat sources
• Where an excessive amount of dust, salt, or iron is present
• Where there are corrosive or explosive gases
• Where water, oil, or chemicals may splash
• Where the level of mechanical vibration is high
We recommend that the instrument be stored in an environment where the temperature
is between 5 and 40
°
C and the relative humidity is between 20 and 80% RH.
