3.2 Installing the Main Unit
Installation Position
Place the instrument in a flat, horizontal position as shown in the figure below. To tilt the
screen slightly forwards, use the support, as shown below also.
When using the support, pull it forwards until it is at right angles to the bottom of the
instrument, and lock it. If you are installing the instrument in a slippery place, attach the
rubber stoppers to all feet to prevent the instrument from sliding.
Support
Installation Conditions
The instrument must be installed in a place where the following conditions are met.
Ambient temperature and humidity
Ambient temperature: 5 to 40 °C
To ensure high measurement accuracy, ambient temperature should be 23 ±2 °C.
Ambient humidity: 20 to 80% RH
No condensation should be present. To ensure high measurement accuracy, ambient
humidity should be 55 ±10% RH.
Flat, horizontal locations
Place the instrument in a stable location, which is horizontal in each direction. Operating the
instrument in an unstable location may hinder recording of the printer and accurate
measurement.
Well-ventilated location
Vent holes are situated on the left side of the instrument. In addition, vent holes for the
cooling fan are also situated in the rear panel. To prevent a rise in the internal temperature,
the vent holes should not be blocked and sufficient clearance should be maintained around
them.

If the instrument is equipped with a built-in printer or when the GP-IB cable is connected,
make sure to allow sufficient space for operations in addition to the space for the vent holes.
Never install the instrument in any of the following places.
• In direct sunlight or near heat sources
• Where an excessive amount of soot, steam, dust or corrosive gases are present.
• Near strong magnetic field sources
• Near high voltage equipment or power lines
• Where the level of mechanical vibration is high
• In an unstable place
Note
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 such cases allow the
instrument to acclimatize to its new environment for at least one hour before starting operation.
