1 INTRODUCTION 1
The MET 400 inverted microscope sets a new standard for inverted metallurgical microscopes.
It combines high performance and distinctive styling with the high quality craftsmanship for which Labomed is known. The
excellent image and comfort of use are the basics of Labomed MET400.
The ergonomics of the design, an aesthetically configured MET400 is the instant choice for Metallurgical Studies & relative
sciences. Offered with Infinity Corrected True color optical system, choices of observation tubes, soft feel
turret movement, stage with micro manipulation offer a paramount performance.
The user should be aware that the protection provided by the equipment may be impaired if used with accessories not
provided or recommended by the manufacturer or used in a manner not specified by the manufacturer.

of personal injury or damage to this Instrument. It is recomended for
your safety to read the manual throughly & do not discard this
manual rather preserve it for easy reference while operating for best
results.
2 To avoid potential electrical hazards when replacing halogen bulb,
turn the microscopes main switch to the OFF position and
disconnect power cord from wall outlet in advance. Whenever you
replace your microscope bulb, allow lamp socket and bulb to cool
before touching (Fig. 1)

Illuminator
The Illuminator Unit is to be fixed to the main Microscope Body with 3 screws using Allen wrench supplied along with
Illuminator. Three Tapped Holes are provided in the Base Unit as shown in Diagram below.
Important Note: Make sure the Power Cord is not connected at this stage.
After the Illuminator Assembly is properly fixed, connect the cable from Lamp House to the Socket provided in Base of
Microscope as shown in below picture.
Adjusting the Aperture Diaphragm
In order to achieve good resolution of the optical image, the contrast and depth of focus it is necessary to control the numerical
aperture of the Illumination system through the lever provided on the illuminator - See Diagram above.
1. Place a specimen with plain surface on the stage.
2. Focus on the specimen with 10x Objective.
3. Remove one of the Eyepiece & look through the Eyepiece Tube to ensure the diaphragm image is visible in the
pupil of the Objective
4. It is recommended to keep the Aperture Diaphragm image in nearly 3/4th of the pupil of Objective. Adjust with
aperture lever your required image quality.
Reducing the aperture increases the contrast & the depth of focus. Increasing the aperture increases the brightness &
resolution.

Observation Head
Mounting the Objectives
Mounting of Eyepieces
Base unit is assembled with co-axial focus mechanism, turret and stage
plate, as per procedure below:
Install the observation head using the following procedure as shown in
Fig. 4:
1. Using the 3mm allen wrench (provided), loosen the Head
Locking Screw (1) and remove the dust cover cap provided in
dovetail cavity as well as on the observation head dovetail.
2. Mount the Observation Head by engaging the dovetail provided
at the bottom of the head into the dovetail cavity provided in the
microscopes arm.
3. Tighten the Head Locking Screw (1) after positioning the
Observation Head as desired. See figure 4.

Insert the eyepieces into the ocular tube of Observation Head after
removing the protective caps from the observation tube.
For Dioptre Adjustment on Eye Piece See Page 7
Settle down the nosepiece by rotating coarse adjustment knob towards
back. Remove the dust prevention caps from the nosepiece.
Screw the objective with the lowest magnification into the revolving
nosepiece from the left side of the microscope. Turn the nosepiece
clockwise and mount the remaining objectives in ascending
magnification order. (Fig. 5)
Clean the objectives periodically.
Be sure to cover any unused threaded position on Turret
with the dust prevention caps to prevent from dirt and dust
from getting inside.

INITIAL SETUP & ASSEMBLY
4Adjusting the Interpupillary Distance (IPD)
Fig. 7
The inter-pupillary distance adjustment consists of regulating the two
eyepieces to align with both the eyes’ pupils so that you can observe a
single microscopic image through two eyepieces in stereo vision. This
greatly helps to reduce fatigue and discomfort during observation.
While looking through the eyepieces, move both eyepieces laterally until
the left and right fields of view coincide completely. The position of index
dot (•) indicates the inter-pupiliary distance value.
Note your interpupillary distance so that it can be quickly referred to in the
future. This is especially important if multiple users work with the
microscope.
5Adjusting the Diopter
Using the Eye Guards
When Wearing Eyeglasses
Use with the eye guards in the normal, folded-down position. This will
prevent the eyeglasses from being scratched (Fig # 9 Part 1).
When Not Wearing Eyeglasses
Extend the folded eye guards outwards (direction of the arrow) to prevent
ambient light from entering into your line of vision (Fig # 9 Part 2).
Fig. 8
Fig.9
Adjust the Diopter setting to “0” position by matching the fiducial lines on
both eyepieces. Now looking through one eye piece (eith ,
turn the coarse and fine focus adjustment knobs to bring the specimen into
focus.
Adjust the focus of other side of eye piece by looking through it and at the
same time optimizing the Dioptre scale of the Eye Piece.

*Make sure the Power Cord is not connected.
Use only recommended 6V-30W high intensity Halogen bulb.
Applicable bulb replacement 6V-30W Halogen Bulb P/No.
EL-455.
Pull out the lamp socket and pull out the blown bulb using a soft
cloth. Gently insert the new bulb. Do not squeeze or press the
bulb too much as it can cause damage to the bulb and hand.
Fit the lamp socket by aligning the guide pins with the condenser
guide holes. Push the lamp socket gently into the transmitted
light illuminator. (Fig. 11, 12)
