installation may cause failure of the instrument.

(1) Small line voltage variation

The line voltage variation is preferably within

+5 % of the line voltage. The instrument will

not operate normally if it is more than +10 %

of your line voltage.

(2) Use a 3-pin grounded outlet (or with a ground­

ing terminal).

If a 2-pin outlet is used, use the supplied 3P-

(3) Small temperatu~~ variation

The temperature variation is preferably 15°C to

25°C. The operating temperature range is 10°C

to 35°C.

(4) Humidity must be within the range of 35% to 85%.

High humidity will accelerate the deterioration

of optical elements. It is therefore recommended

to install the instrument in a place where humid­

ity is lower than 60%.

(5) The atmospheric pressure must be 750 to 1060

millibar.

(6) No intense magnetism or source of high frequency

The instrument may not operate normally in the

vicinity of intense lines of magnetic force

or a source of high frequency.

(7) Small mechanical vibration

- 3 -

Page 8: MODEL 7800 SPECTROPHOTOMETER (LCD TYPE) INSTRUCTION …

(8) Avoid installation in a dusty place or a place

where harmful gas such as corrosive gas or the

like is present.

(9) Install the instrument in a place not exposed

to direct sunlight.

(10) Install the instrument in a place not directly

blown with air from an air conditioner.

1-2-2 Installation and connecting connectors

Install the instrument on a bench or table measuring

600 mm wide and 550 mm deep, which withstands a weight

of 15 kg.

After making sure the " POWER" switch at the bottom

of the right - hand side panel of the main unit is ln

the "OFF " position, connect connectors. Connect

one end of the AC input cord to "AC lOOV INLET" on

the rear of the main unit and t h e other e nd to your

outlet. The instrument can be grounded by plugging

the cable to a 3-pin outlet with a grounding terminal .

If your outlet has no grounding terminal, ground the

grounding terminal on the rear of the main unit

Fig. 1-3

I WARNING I (1) Make sure that the grounding wire of

the 3-pin outlet is grounded.

(2) Do not use a water supply pipe for

grounding because it is often made of

non-metal materials. Correctly ground

the instrument using the grounding

t e rminal on your power distribution

board. If it is not grounded , you may

receive an electric shock in case

insulation failure.

1-2-3 Loading heat-sensitive chart paper

CAUTIONS: (1) The heat-sensitive chart paper has

its face and back. Be sure to load

it so that print is made on the face.

(2) Be sure to load the chart paper before

using the printer . Operati o n without

loading chart paper may damage the

thermal head.

- 6 -

Page 11: MODEL 7800 SPECTROPHOTOMETER (LCD TYPE) INSTRUCTION …

<Cautions in handling heat sensitive chart paper >

The heat sensitive chart paper will develop color

by heat. Color development is noticeable from

about 75°C . Use the following care in handling

the chart paper.

(1) Do not store it in a place where temperature

and/or humidity is high. Store it in a dark

place where temperature is lower than 30°C and

humidity lower than 60%.

(2) Use care not to wet the chart paper. If the

recording area is wetted with water, do not rub

the surface with force , but liqhtly press it

with tissue paper or the like and allow it to

dry.

(3) Do not rub chart paper with a hard ob j ect. If

rubbed , it may develop color by friction heat.

(4) Exposure to intense light for an extended time

after color has developed may fade it. Keep it

in a file, as and if necessary.

(5) For pasting, do not use a solvent-based paste.

Use of organic solvent may develop color.

Appropriate adhesives include starch-based paste ,

gum arabic , and poval-based or CMC - based

adhesive.

(6) Plasticizer may fade the recording area. Do not

- 7 -

Page 12: MODEL 7800 SPECTROPHOTOMETER (LCD TYPE) INSTRUCTION …

stick cellophane tape directly to the recording

area or do not allow plastic film containing

much plasticizer to be in direct contact with

it for an extended time.

3. GENERAL DESCRIPTION OF INSTRUMENT

3-1 Optical System

This instrument measures the absorption of a sample

in the ultraviolet/ visible/near infrared region of

200 to 1100 nm wavelengths to make quantitative

analysis. It can also measure the absorpiton spec­

trum, as a matter of course.

Fig. 3-1 shows the optical system of this instrument.

It uses a deuterium lamp in the ultraviolet region

and a tungsten iodine lamp in the visible-to-near

infrared region as the light source. The light from

the light source, after passing through a high order

light cut-off filter, goes to the monochromator that

uses a concave diffraction grating. The light is

monochromated by the monochromator and is split into

two beams by the beam splitter. One of the beams

pass through the sample and the other the reference

sample such as a solvent or other and is incident on

the silicon photocell detector.

After the light signal is converted into an electrica l

signal by the detector and amplified , it is subjected

to A-D conversion. The data thus converted is subjected

to necessary processing by a microcomputer and is

output.

APPENDIX 1 REPLACEMENT AND POSITIONAL ADJUSTMENT OF LIGHT

SOURCE

The life expectancy of the light source is approximately

1,000 hours for both the deuterium (D 2 ) lamp and tungsten

iodine (WI) lamp. After prolonged use of the lamp,

increased noise will appear on the data because of reduced

light quantity .

(1) Replacement of lamp

<Cautions in replacing light source>

1) The lamp is heated to a high temperature whi le it is

lit. Replace the lamp more than ten minutes after

turning OFF the light source.

2) Before replacing the lamp, turn OFF the "POWER" switch

and disconnect the AC power cord from the outlet.

3) In replacing the lamp, never loosen any screws except

the one to be loosened.

4) Wear clean cloth gloves when handling the lamp.

5) Never touch the mirror

6) If the lamp is contaminated, wipe it with gauze or the

like wetted with ethyl alcohol and then wipe with

clean dry gauze.

[Rep lacement of tungsten iodine (WI) lamp]

1) Slide the outer lid of the light source to remove it

and then remove the inner lid.

If the beam from the light source is not accurate l y

incident on the entrance slit, problems will occur such

as insufficient light quantity, curved baseline and

variations of the measurement values at the time of

changing over the light source. The light source

condenser mirror and light source need adjustment when

the light source is replaced.

I WARNING I (1) Never touch a lit lamp with naked hand.
