MEC2 INVERTED METALLURGICAL MICROSCOPE

SAFETY NOTES

1. Open the shipping carton carefully to prevent any accessory, i.e. objectives or eyepieces, from
dropping and being damaged.

2. Keep the instrument out of direct sunlight, high temperature or humidity, and dusty environments.

3. If any specimen solutions or other liquids splash onto the stage, objective or any other component,
disconnect the power cord immediately and wipe up the spillage. Otherwise, the instrument may be
damaged.

4. LAMP REPLACEMENT -- CAUTION: the glass envelope of the lamp may be extremely

hot. DO NOT attempt to change the lamp before it is completely cooled or without
wearing adequate skin protection.

5. All electrical connectors (power cord) should be inserted into an electrical surge protector to prevent
damage due to voltage fluctuations.

6. FUSE REPLACEMENT -- For safety when replacing the fuse (ONLY replace with the

same size, type and rating of original fuse), be sure the main switch is in the off position,
disconnect the power cord from outlet, and replace the fuse. Reconnect the power cord
and turn unit on.

7. Confirm that the input voltage indicated on your microscope corresponds to your line voltage. The
use of a different input voltage other than indicated will cause severe damage to the microscope.

NOTE: Always plug the stereomicroscope power cord into a suitable grounded electrical outlet. A

grounded 3-wire cord is provided.

CARE AND MAINTENANCE

1. Do not attempt to disassemble any component including eyepieces, objectives or focusing assembly.

2. Keep the instrument clean; remove dirt and debris regularly. Accumulated dirt on metal surfaces
should be cleaned with a damp cloth. More persistent dirt should be removed using a mild soap
solution. Do not use organic solvents for cleansing.

3. The outer surface of the optics should be inspected and cleaned periodically using an air stream from
an air bulb. If dirt remains on the optical surface, use a soft, lint free cloth or cotton swab dampened
with a lens cleaning solution (available at camera stores). All optical lenses should be swabbed using
a circular motion. A small amount of absorbent cotton such as a Q-tip or cotton swab, makes a useful
tool for cleaning recessed optical surfaces. Avoid using an excessive amount of solvents as this may
cause problems with optical coatings or cemented optics or the flowing solvent may pick up grease
making cleaning more difficult.

4. Store the instrument in a cool, dry environment. Cover the microscope with the dust cover when not
in use.

5. UNITRON® microscopes are precision instruments which require periodic servicing to maintain
proper performance and to compensate for normal wear. A regular schedule of preventative
maintenance by qualified personnel is highly recommended. Your authorized UNITRON® distributor
can arrange for this service.

INTRODUCTION

Congratulations on the purchase of your new UNITRON® microscope. UNITRON® microscopes are
engineered and manufactured to the highest quality standards. Your microscope will last a lifetime if
used and maintained properly. UNITRON® microscopes are carefully assembled, inspected and tested
by our staff of trained technicians in our New York facility. Careful quality control procedures ensure each
microscope is of the highest quality prior to shipment.

UNPACKING AND COMPONENTS

Your microscope arrived packed in a molded shipping carton. Do not discard the carton: the shipping
carton should be retained for reshipment of your microscope if needed. Avoid placing the microscope in
dusty surroundings or in high temperature or humid areas as mold and mildew can form. Carefully
remove the microscope from the shipping carton and place the microscope on a flat, vibration-free
surface.

DETAILED ASSEMBLY PROCEDURE

Attaching the Mechanical Stage
And X-Y Controls

The mechanical stage may be installed in either
side of the stage to enlarge the stage surface.
The x-y controls must be installed on the
opposite side of theauxiliary stage.

Generally, the x-y controls are installed on the
right side for comfortable operation.

Installing The Mechanical Stage

Screw the clamping bolts into to the mechanical
stage, then into the fixed stage from below on
either the right or left side. Tighten the bolts with
a screwdriver until the mechanical stage is
securely attached.

Installing The X-Y Controls

Install the ruler using the same method as the
mechanical stage.

Bulb (Figures 1-3）

Use only the specified halogen lamp: 6V 30W

1. Pull out the lamp house① (Figure 1)

2. Holding the bulb ① with a piece of gauze or
other protective material, insert the bulb pins

straight and fully into the pin holes③ on the
lamp house. (Figure 2)

CAUTION: The bulb, lamp housing and
nearby parts will be very hot during usage.

3. When replacing the lamp, turn the main
switch to “O (off) and remove the power cord.
Allow the lamp, lamp house and adjacent areas
