RMM2 ROLLSCOPE 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.

RMM2 ROLLSCOPE MICROSCOPE

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.

The RMM2 Series Rollscopes are portable, compact, metallurgical camera-microscopes designed for
measuring and photography of inaccessible or large objects that cannot be placed on the stage of an
ordinary microscope.

RMM2 models can be furnished with optional easy-to-read dial gauges at eye level. In addition, the
RMM models have the added feature of built-in graduated rack and pinion X-Y motion to traverse the
object being studied. This feature is most desirable when using high-power objectives, as well as in
choosing and composing areas for photography.

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.

Unless you have specified otherwise, the RMM2 Rollscope is furnished with the following:

EYEPIECE: 10x Widefield high eyepoint

MICROMETER RETICLE: Installed in eyepiece; engraved scale; 10mm with 0.1mm divisions or 0.4 inch

with 0.01 inch divisions depending upon model selected

ILLUMINATOR: Vertical illuminator with condenser system, diaphragm, filter holder and two knurled
screws. Two filters (yellow and green) are included to enhance contrast. The knurled centering screws
are used to adjust the position of the bulb for optimum illumination. Also included are two types of bulb
socket and cord assemblies; one is used for AC operation with the transformer and the other is for DC
operation with batteries.

OBJECTIVES: Plan achromat 5x, 10x, 20x & 50x
