2.1 lnstallation Site

The microscope should be operated

in a room with as

little

dust as

practically possible.

Keep

your

instrument away from solvents, chemical

fumes and excessive

humidity. Also try to

avoid big

swings

in ambient temperature, direct

sunlight and

vibration

as

they

can affect

measurements and

instrument oerformance.

Unpacking

Please

check

your packing

slip to

insure that all materials are

present.

Keep

a copy

for

your

records

so

that

you

have the

proper

information when ordering

more

equipment, ordering

replacement

parts

or

accessories or

when calling for technical support.

Please make sure that no small

pieces

or

parts

are

lefl

in the

packing

material.

Keep the

packing

materials in a safe

place

for the

purpose

of storage and

transporting

the microscope and its accessories.

lAnrremor.rl

Avoid touching

the surface of optical components such

as lenses, filters and

glass

surfaces.

Even very

small

traces of

perspiration

or

finger

oils

can corrode the surfaces of optics

in

a short

period

of

time.

2.3 Microscope

Set

Up MT9200 & MT9300

o

As a first

step,

remove

all components

from

the shipping

container and

remove the

packing

materials

and

place

the

microscope

frame

on a stable

work

surface.

Place

the analyzer-

Bertrand

lens

module

onto the

frame

and tighten the clamp screw

to

secure the

module.(Fig.1)

Next,

place

the binocular

head

(MA952)

or

trinocular

head

(MA953)

on

the

top of the analyzer-

Bertrand lens

module

and tighten the clamp screw

while the head

is

in the

correct

position

as

shown

right.(Fig.2)

o

lnstall

the

Siedentopf

head with the 2mm

allen

wrench

supplied

being careful to align the notch

in

the

head with the

set

screw.(Fig.3)

Next,

install the MA407CP

focusing

eyepiece

by

sliding

it

into the

slotted

right

eyetube and

install

the

other

eyepiece

(MA407)

into the left

eyetube.

The

rubber

eyeshields

can

also be

installed

on

top

of each eyepiece.

The

eyepieces

for

MT9000

Series

are a

DIN

standard

23.2mm

diameter.

o

Remove

the objectives

from

their

objective

cases

while being

careful

not

to

touch

any

part

of

the

optics. Strain

free

objectives

are

marked with

the

letter

"POL"

in red

and are

very

sensitive and

are susceptible

to

pressure

or

impacts. They

should only be

handled

by

the knurled collar.

Gently screw

the

10X

objective

into

the

"fixed"

opening of

the

nosepiece

(the

opening

that does

NOT

have centering screws).(Fig.4)

Install

the rest of

the

objectives

incrementally in

order

of

power

(e.9.

4X,

40X, 60X,

etc).

o

Plug

the

power

cord into

the

microscope

and

the

other

end into a

grounded

outlet.

(Fig.5)

Your MT9000 & MT9400

Series

Microscope

and standalone

power

supply

have

automatic

voltage

sensing so

they

can be used

with

any

voltage f rom

any

country

in the world

f rom

100 volts to 260 volts AC

with the

proper

cordset.

,Acourre!

l

The mains

power

cord should

only be

plugged

into a known

grounded

outlet. A simple outlet

tester

can

be

used to

verify

correct

outlet

polarity

and

the

presence

of

a

grounded

circuit.

lf no

other

accessories

are

going

to

be

installed,

the instrument

is now ready for

use.

Set Up MT942O & MT9430

o

As a first

step,

remove

all

components

from

the

shipping

container and

remove

the

packing

materials

and

place

the

microscope

frame

on a

stable work

surface..

o

Models

MT9420 and MT9430 have a vertical illuminator

(MA955)

which is installed

on top

of

the microscope frame first.(Fig.6)

Next,

mount the

Analyzer-Bertrand

Lens module

on the

vertical

llluminator,

place

the

binocular

head

(MA952)

or trinocular head

(MA953)

onto

the top

of

the Analyzer-Bertrand lens

module

(if

installed)

and

re-tighten

the

clamp screw while the head

is

in the

correct

position

as shown

right.(Fig.7)

o

lnstall the

Siedentopf

head with

the

2mm

allen

wrench

supplied

being careful

to

align the

notch

in

the

head with

the set screw.

Next,

install the MA4OTCP

focusing

eyepiece by sliding

it

into the

slotted

right

eyetube and

install

the

other eyepiece

(MA407)

into

the left

eyetube.

The rubber

eyeshields

can

also be

installed

on

top

of each

eyepiece.

The

eyepieces for MT9000

Series are a

Df N

standard 23.2mm diameter.

o

Remove

the objectives

from

their

objective cases while being

careful

not to

touch any

part

of the optics. Strain

free

objectives

are

marked

with the

letter

"POL"

in red

and

are

very

sensitive

and

are

susceptible to

collar. Gently

screw

the 10X

objective

into

the

"fixed"

opening

of

the nosepiece

(the

opening that

does

NOT

have

centering screws).

Install

the

rest

of the objectives

incrementally in

order of

power

(e.g

20X,40X,

60X,

etc) .(Fig.

)

o

Plug

the cord

from

the

vertical illuminator

into the

back

of the

standalone

power

supply

(MA927l05XFig.9)

and

plug

the

power

cordset

into

the

microscope

and

the other end

into

a

grounded

o utlet.

(Fig.5)

Your

MT9000

or

MT9400

Series

Microscope

and standalone

power

supply

have

automatic voltage sensing

so

they

can be used
