3.2 Installing the Instrument
Installation Condition
Install the instrument in a place that meets the following conditions.
Ambient Temperature and Humidity
• Ambient temperature: 5 to 40
°
C
• 20 to 80% RH (no condensation)
Flat, Even Surface
Install the instrument in a stable horizontal place. Accurate measurements may be
hindered when the instrument is used in an unstable place or tilted position.
Well-Ventilated Location
Vent holes are located on the top and bottom of the instrument. To prevent internal
overheating, do not block the vent holes.
If you remove the legs from the bottom panel for rack mounting, allow an equivalent
amount of space (20 mm or more) from the floor to prevent blocking the vent holes.
Do Not Install the Instrument in the Following Places:
• In direct sunlight or near heat sources.
• Where the level of mechanical vibration is high.
• Near noise generating sources such as high voltage equipment and power source.
• Near strong magnetic field sources.
• Where an excessive amount of soot, steam, dust, or corrosive gas is present.
• In an unstable place.
Note
• For the most accurate measurements, use the instrument in the following environment.
Ambient temperature: 23
±
5
°
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 as specified in chapter 16.
• 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.
• 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 the instrument.
Installation Position
Desktop
Place the instrument on a flat, even surface as shown in the figure below.

When using the handle for installation, check that the handle is in one of the fixed
positions. To change the fixed position of the handle, pull the handle outward
along the rotational axis approximately 2 to 3 mm and slowly move the handle.
