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.
(☛ See section 4.2 Handling the Optical Connectors)
･Output level down
・Output level instability
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
zThe 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.
zIf 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. (☛Contact information is located at the end of this
document.)

4 Power supply and power cord Safety Precautions
viii
4 Power supply and power cord
The AQ4305 is Class I safety class equipment which has a protective ground and is structured to provide
sufficient protection against electric shock.
This unit can be grounded to protect against electric shocks from AC power supplies by connecting the
ground pin of a three-prong power cord or the ground terminal of a 3-prong/2-prong adapter to a power
outlet.
(1) Power supply
The AQ4305 works with 100-120,200-240V AC power supplies. The supply frequency
should be in the range of 48–63 Hz. In addition, use a rated voltage cable that satisfies
the operating voltage requirements.
(2) Power cable
The power cable is a 3-pin plug-type cable in which the pin in the center serves as the
ground pin. To the extent possible, this unit should be connected to a 3-prong outlet. If
you use a two-prong outlet, connect the power cable to the outlet through an adapter.
The ground wire from the adapter must be connected to an external ground or the earth.
4.1 Safety measures related to power supply
The AQ4305 will operate normally with 100-120,200-240V AC/48–63 Hz power supplies. However,
steps must be taken to protect against the following in supplying the AC power.
･Injury due to electric shock
･Damage to the unit’s interior due to abnormal voltage
･Problems caused by ground current
(1) Power cord polarities
A 3-prong (or grounded-type 2-prong) power outlet with an earth terminal
(E) is connected as shown in Fig. 1 to the live line (L), neutral line (N),
and protective earth line (earth ground). Therefore, the included 3-wire
power cord is designed so that the power supply polarities will match
when the plug on the cord is simply inserted in a 3-prong (or grounded-
type 2-prong) outlet.
