SAFETY SUMMARY
REMARKS ON SAFETY OF SPECTROPHOTOMETER
Electricity
(1) Confirm power supply to spectrophotometer.
Fluctuation in voltage or noise on power line would not only affect spectrophotometer mainframe
adversely but also cause an accident.
(2) Be sure to provide grounding connection along with power connection.
(3) High – voltage circuits are used inside spectrophotometer. Do not open any other cover than
necessary for operation.
Fire
Avoid smoking and using a fire in the vicinity of spectrophotometer.
Data Backup
Data may become unusable in case of instrument failure or misoperation.
It is recommended to transfer data from hard disk to a flash disk periodically. Transfer of data is called
backup.
To avoid misoperation, secure a free space of 100MB or so on the hard disk as a software word area at
all times.
Computer Virus
If programs or data has suddenly been destroyed, if an unexpected operation takes place or if an
abnormal display appears on screen, your personal computer may have been infiltrated by a computer
virus. Computer virus is a rogue program that secretly invades a personal computer and operates it
willfully while destroying memorized data.
A program for eliminating the virus is called vaccine program.
There is a possibility of contamination with a program including a computer virus, or by using an
exchangeable recording medium such as a flash disk that contains a computer virus. Also, it is possible
to transmit the virus from one personal computer to another via communication or recording media. So
avoid using a program or recording medium that might include a virus.
Carry out check using a vaccine program if there is a possibility of contamination with a virus. But
depending on type of vaccine program, it may be impossible to eliminate virus.
It is therefore recommended to back up contents of hard disk beforehand.
Power Failure
A power failure or momentary voltage drop of power supply due to lighting, etc. may cause failure of
personal computer used with the instrument and also damages system software, application software
and other data. To avoid such problems, it is recommended to use an AC uninterruptible power
source.
Personal Computer (PC)
Do not t urn off PC power supply alone. If PC power supply is turned off during access to hard disk or
flash disk, PC may be damaged and data or software stored in it may be destroyed. To turn off PC
power supply, be sure to complete spectrophotometer control and data processing program before
taking shutdown procedure for system software.

Particular attention must be paid to Deuterium lamp because it radiates
intense ultraviolet rays.
2. CAUTION ON USE
Optical parts are fragile. Besides, control and data processing sections
comprise high – density electronics. Therefore, precautions below must
be taken without fail.
(1) Avoid giving shock or vibration to optical parts. Do not breathe
on optical parts or touch them with bare hands.
(2) For removing dust from optical parts, blow it off by using a hand
sprayer which jets out clean dry air. Do not wipe them with a
cloth or the like.
(3) The operating temperature must be within 5
0
C to 35
0
C.
However, optimum condition is restricted to a range to 200C to 250C.
Hence, installation in an air – conditioned room is recommended.

benzine and thinner).
(7) Avoid direct sunlight. (Otherwise optical performance might
deteriorate. Do not locate the instrument near a window
whenever possible.)
(8) Do not allow strong vibrations nor shocks beyond a level which
can be sensed by the human body. (Otherwise delicate
adjustment mechanism might run out of order.)
(9) Protect the instrument cover from excessive heat (beyond
700C) radiated form a gas burner, heater, oven or the like.
(10) The instrument must be located away from equipment which
generates a strong electric field (such as an electric welding
machine, high-frequency electric furnace and pole transformer).
(11) Dusty environment is unallowable. (Otherwise adequate optical
performance might not be ensured.)
(12) Line voltage must not fluctuate suddenly (otherwise noise might
increase). Its fluctuation must be within ±10%.
(13) Do not turn on/off frequently power supply to a motor (stirrer,
vibrator, etc.) without a noise - preventive device in same power
line as the instrument’s.
(14) The installation plane must be level and capable of bearing a
weight of about 25Kg or more.
(15) Minimum power requirements are 90VA. But a higher power
capacity (1KVA or more) must be prepared in order to allow
another instrument to share power line.
(16) Fluctuation of power frequency must be within +0.3 to –1.0% of
rated frequency (50 or 60 Hz).

2.4 Optics schematic diagrams
Monochromatic light emitted from monochromator has achieved an ultra-small stray light without
degrading high resolution through series connecting that of monochromator grating. Monochromatic
light is led into sample compartment, in which beam passes through reference and unknown sample.
Beam transmitted through reference and sample is incident on detector, namely a solid silicon
photodiode.


10%
Fluctuation must be within ±10% of rated level.
3.1.2 Frequency 50 or 60 Hz
Fluctuation must be within +0.3 to –1.0% of rated level.
3.1.3 Power capacity Suggest to prepare 1KVA or more since power may be shared with
another instrument.
3.2 Conditions for installation
3.2.1 Installation area At back - side of the instrument, it is desirable to secure enough space
(100mm or more) to emit heat.
3.2.2 Installation plane Installation plane must be level and capable of bearing a weight of
about 25Kg or more.
3.2.3 Environment at place for installation
1) Operating temperature
50C to 350C.
For stable measurement, room temperature should preferably be
controlled within a range of 200C to 250C by an air-conditioner.
2) Operating humidity
45% to 85%
3) Storage temperature
-200C to 700C.
4) Atmosphere
a. Must be free from acidic, alkaline and other vapors which
will corrode metals heavily.
b. Must not contain the vapor of organic solvent (particularly
benzine and thinner) which will dissolve coating.
5) Other general cautions
a. Avoid direct sunlight and provide as large a distance as
possible from a room window.
b. A strong vibration or shock that can be felt by human body
must not be transmitted to the instrument.
c. Avoid vicinity of heat generating apparatus such as a gas
burner, electric heater or oven in order to prevent instrument
cover being heated (beyond 700C).
d. Avoid vicinity of instruments which generate a strong
electric field (such as an electric welding machine, high
frequency furnace and pole transformer).
e. Dusty environment is unallowable.
f. The line voltage must be free from wide and sudden
fluctuations.
g. Do not turn on and off frequently electric instruments (stirrer,
vibrator, etc.) which are not provided with a noise –
