3 Usage Environment
3.1 Operating temperature range
The operating temperature range at which the AQ4305 operates normally is +5 to +40
°
C.
3.1.2 Environmental conditions
This unit contains 3-linear guide stages for adjusting the position of lamp, so it is important to
avoid extreme temperatures, shock impacts, and vibrations in storing and transporting the unit.
In particular, if the following environmental conditions are exceeded, this unit’s performance
levels may not recover.
Environmental conditions
(1)
Storage temperature range: − 10 to +50
°
C
(2) Vibration
Oscillation frequency: 10 Hz
Compound amplitude: ±0.25 mm
Vibration directions: Up/down, left/right, forward/backward
Vibration duration: Vibrations equivalent to 10 minutes in each
vibration direction
(3) Shock impact: Shock impact equivalent to natural fall when the unit is resting on a
hardwood floor and one side of bottom is lifted 5 cm
3.1.3 Usage precautions
(1) Halogen lamp
Halogen lamp must be handled carefully because a forceful shock impact could break
the filament, or could damage the bulb.
(2) Handling problems
If you experience problems such as those listed below, there may be debris adhering to
the end of the optical fiber cord which connects the instrument to this unit. In such
cases, clean the end of the optical fiber cord with alcohol or the like.

3.1.4 Installation
If this unit is left in a vertical or upside-down position for an extended period of time, the 3-
linear guide stages will be adversely affected. Always use this unit in a horizontal position.
Install this unit in a stable location for use. If it is installed in a location with heavy vibrations
or if it is vibrated or jarred during operations, output level will become unstable.
This unit must also be kept in a horizontal position during transport and storage.
Caution
z
The AQ4305 contains 3-linear guide stages. If this unit is installed in a location with heavy vibrations
or if it is vibrated or jarred during operations, output level will become unstable. Therefore, be sure to
install this unit in a stable location for use.
z
If output level changes significantly, adjust xyz-axes. (
☛
See section 4.3 Xyz-axes Adjustment.) If this
unit’s performance are not restored/improved as a result of adjusting by turning the power off and then
back on, repairs will be necessary. In such cases, contact the sales department at our main office, or
the nearest branch office or sales office. (
