Bulb Installation:

1. Mount the bulb in the bulbholder by pushing and twisting it 1/4 turn clockwise.

Transmitted Illuminator Installation:

1. Mount the Transmitted illuminator on the microscope base by inserting it into the mounting ring at the rear of the base with the screw (a) and the filter holders (b) uppermost.

2. Clamp in place with the clamp screw.

Oblique Illuminator Installation:

1. Insert the bulb into the Oblique illuminator as described in the bulb installation step.

2. Remove the Clamp Ring from the microscope body by turning it counterclockwise.

3. Put the Ring arm of the Oblique illuminator over the fine focusing knob and clamp it in place using the clamp ring.

4. Plug in and adjust the position of the illuminator to light up the specimen correctly. The oblique illuminator can be mounted on either side of the microscope.

Vertical Illuminator Installation:

1. Insert the bulb as previously described.

2. Remove the dust cap from the top of the microscope body and loosen the knurled Lock ring by turning it counterclockwise.

3. Plug in and insert the vertical illuminator into the microscope body, and clamp with the knurled Lock ring.

Main Tube, Eyepiece, and Objectives:

1. Mount the Main tube on the microscope by screwing it into the body.

2. Insert the Eyepiece into the Main tube. Adjust the direction of the reticle so that the dotted crosslines are correctly horizontal and vertical, then lock it with the Lock ring.

3. Focus the reticle sharply by turning the upper part of the eyepiece.

4. Mount the objective/objectives on the objective nosepiece. For Model MTM253, mount the objectives starting with the lowest magnification, and increasing magnification as the nosepiece is turned counterclockwise.

Stage Preparation:

1. Remove the metal transit rods, which prevent movement of the stage during shipping, by loosening the clamp screws. Be careful as the stage is spring-loaded.

2. Install the Digital micrometer head by inserting the stem into the mounting bracket and clamping it in place. Note: Do not over-tighten the clamp screw as this will affect the operation of the micrometer head.

a. Place a specimen on the stage under the stage clips. If the stage clips are not required, remove them by pulling upward.

b. Focus the objective on the specimen by rotating the large coarse focusing knob until the image of the specimen is bright and clear. Then turn the Locking-lever to lock the body.

c. Then, bring the specimen into sharper focus by using the fine adjustment knob.

(The working distance for a 10X objective is 6.6mm)

a. Rotate the stage so that the movement of the specimen coincides with the horizontal line of the eyepiece reticle.

b. Using the micrometer head, move the stage to bring the starting point of the measurement under the center of the crossline reticule. Now, read the graduation on the Micrometer.

c. Move the stage to bring the end point of the measurement under the center of the crossline reticle. Read the graduation. The difference between the readings in b. and c. is the dimension of the object being measured.

d. For operation of the Digimatic Head (Digital micrometer head), please refer to the manual supplied with that instruction.

When using the Digital Micrometer Heads, please refer to the instruction manual for the DIGITAL MICROMETER HEAD as supplied by the manufacturer.

The Digital indicator is used for measuring height/depth.

a. Attach the extension rod to the Stem before inserting it into the microscope.

b. Insert the Digital indicator into the gauge tube on the top of the microscope body and clamp with the knurled lock ring.

c. Focus the objective sharply on the highest point of the specimen to be measured and follow the instruction manual of the Digital indicator for measurement of height.

For television, the MA580 TV Camera Adapter must be used.

Please refer to the separate Instruction Manual for MA150/60 Camera attachment.

Always cover the instrument with the plastic dust cover provided when the microscope is not in use. Keep the eyepiece in the microscope body at all times to prevent dust from falling on the internal optics.

Store the microscope in a safe, clean, and dry place when not in use for an extended period of time.

Clean exposed lens surfaces carefully with a pressurized air source, soft brush, or clean soft cloth. Too much finger pressure may damage lens coatings.

To remove oil, fingerprints, and grease smudges, moisten the cleaning cloth with a very small amount of alcohol.

Painted or plastic surfaces should be cleaned only with a cloth moistened with water and a small amount of detergent.

DO NOT ATTEMPT TO MAKE ADJUSTMENTS TO THE INTERNAL OPTICS OR MECHANISMS.

If the microscope does not seem to be functioning properly or you have questions about its operation, call your supplier (or an authorized repair service) for advice.

1. Unscrew the Fuse holder and remove the fuse.

2. Remove the larger diameter ring labeled “voltage selector” by pulling it away from the microscope. You will see contact pins and voltage markings (e.g., 110V, 120V, 220V, 240V).

3. The ring has a notch cut out for voltage selection. Reinsert the ring so the notch aligns with your desired voltage, making it visible.

4. Install a power cord with the correct pin pattern for your region.
