MEC2 INVERTED METALLURGICAL MICROSCOPE 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 Fig.
MEC2 INVERTED METALLURGICAL MICROSCOPE Insert the lamp gently but firmly into the socket. Do not touch the halogen bulb with bare fingers. Doing so will shorten the service life of the lamp. If you leave fingerprints on the lamp surface, clean it with a soft cloth or lint free paper. 4. Align the socket ① with the pins ③, and the Fig. 4 bolts ② with the jacks ④. Then insert the lamphouse cover completely into place.
MEC2 INVERTED METALLURGICAL MICROSCOPE Mounting Filters and Polarizer (Figure 10) 1. Insert a standard filter(s) into slot (1) 2. For polarized observation, insert the polarizer filter into slot (2). Standard filters are blue, yellow and green filters Fig. 9 Mounting the Analyzer (Figure 11) Insert the analyzer (3) into the slot under the trinocular viewing head. The analyzer may be used alone or with the polarizer. Fig. 10 Fig. 11 UNITRON® 73 Mall Drive, Commack, NY 11725 • 631-543-2000 • www.
MEC2 INVERTED METALLURGICAL MICROSCOPE Connecting the Power Cord (Figures 12, 13 & 14) The electric cord should never be bent, twisted, crushed or subjected to stress. 1. Set the main switch① to “O” (off) before connecting the power cord. 2. Insert the power cord into the receptacle②. Fig. 12 3. Insert the BNC cord plug (3) into the BNC connector (4). Ensure the power cord is connected to a properly grounded electrical outlet. Replacing the Fuse (Figures 12 & 13) Fig.
MEC2 INVERTED METALLURGICAL MICROSCOPE ADJUSTMENT AND OPERATION Turning On The Lamp (Figure 15) Connect the power cord, then set the main switch① on the side of the base to the “on” Fig. 15 position (“－”). Adjusting The Brightness (Figure 16) Rotate the brightness adjustment knob (2) clockwise to increase the brightness. Conversely, rotating the knob decreases the brightness. Using the lamp at its lowest acceptable intensity will increase the life of the lamp. Fig.
MEC2 INVERTED METALLURGICAL MICROSCOPE Adjusting the Illumination (Figure 18) 1. Make sure the field of view is bright and evenly illuminated, and has no filament shadow. If there is filament shadow, adjust the condenser adjustment knob③ to its proper position. Fig. 18 2. To obtain a clear, sharp image, adjust the field iris diaphragm① and aperture iris diaphragm (2) to their proper positions. One or both diaphragms may need to be adjusted to obtain the sharpest image.
MEC2 INVERTED METALLURGICAL MICROSCOPE Placing and Moving the Specimen (Figures 19 & 20) 1. Place the slide in the center of the stage and secure with the stage clip. 2. The specimen may be moved to different Fig. 19 positions by turning the X-axis knob① and/or the Y-axis knob②. Travel: X-axis (left-right) direction: 120mm Y-axis (front-back) direction: 78mm Use caution when changing the objective to prevent it from touching the stage, stage plate or specimen slide. Fig.
MEC2 INVERTED METALLURGICAL MICROSCOPE Adjusting the Diopter (Figure 21) 1. Looking through the right ocular only with your right eye, use the coarse and fine focusing adjustment knobs to focus on the specimen. 2. Then with your left eye only, look through the left ocular. If the image is not sharp, rotate the Fig. 21 diopter adjustment ring① to focus on the specimen.
MEC2 INVERTED METALLURGICAL MICROSCOPE Light Path Selecting Lever Illumination Application Pushed In 100% for binocular observation Binocular observation Pulled Out 20% for binocular observation Binocular observation and video (CCTV) or microphotography simultaneously 80% for video or microphotography Polarization Observation 1. Insert the polarizer and analyzer as described on page 8 (Figures 10 & 11). 2. The analyzer hand wheel can be rotated from 0 °to 90°.
MEC2 INVERTED METALLURGICAL MICROSCOPE Focusing (Figure 25) Observing through binocular position, focus the specimen until a sharp image is obtained. Then check the image on the monitor to which the microscope is connected. If the image is not sharp, rotate the video adapter (4) until the image is sharp. Microscope Photography (Figure 26) Selecting the Light Path (Figure 24) Follow the instructions on previous page Installing the Photo Adapter (Figure 26) 1.
