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

CARE AND MAINTENANCE

1. Do not attempt to disassemble any component including eyepieces, objectives or the 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 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 wound on the end of a tapered stick 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. ACCU-SCOPE® 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 service personnel is highly recommended. Your authorized ACCU-SCOPE® distributor can arrange for this service.

INTRODUCTION

Congratulations on the purchase of your new ACCU-SCOPE® microscope. ACCU- SCOPE® microscopes are engineered and manufactured to the highest quality standards. Your microscope will last a lifetime if used and maintained properly. ACCU-SCOPE® microscopes are carefully assembled, inspected and tested by our staff of trained technicians in our New York facility.

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.

COMPONENT DIAGRAMS

ASSEMBLY

• The diagram below shows how to assemble the various components. The numbers indicate the order of assembly. For details on assembling and connecting the different c-mounts and camera to the microscope (#5-7 below).
• When assembling the microscope, make sure that all parts are free of dust and dirt, and avoid scratching any parts or touching glass surfaces.

OPERATION

• Setting Illumination For LED Models (Fig. 1)
  • Turn the light adjustment knobs 1 and 2 as shown on the base in Fig. 3: turn clockwise to increase brightness; counterclockwise to decrease brightness.
• Using the Black & White Stage Plate (Fig. 2 )
  • For instruments supplied with a Plain Focusing Stand or Pole Stand, the user can use either side of the Black & White Stage Plate. For samples that are white or other bright colors, the black surface is typically facing up to help increase contrast of the image.
  • For other darker colored samples, the white surface is recommended.
  • To remove the plate or reverse it, press down on the supporting point (Fig 2) so the other side of the plate lifts up for removal/reversing.
• Adjusting the Rotation Tension of the Focus Adjustment Knob (Fig. 3)
  • To adjust tension, hold both left and right focus adjustment knobs with both hands, hold the left knob (to prevent it from turning), and rotate the right knob clockwise to increase (tighten) or counterclockwise to decrease (loosen) the focus knob tension.
  • After tension adjustment has been completed, always rotate both adjustment knobs in the same direction.
• Adjusting Diopter Ring (Fig. 4)
  • Set the diopter rings of both eyepieces to “0” position. (Do this when users change, because different users will have different diopter settings.)
  • Place an easy-to-observe specimen on the stage plate.
  • Rotate the zoom knob to the highest magnification, then turn the focusing knob to focus the specimen.
  • Rotate the zoom knob to the lowest magnification, looking only into the left eyepiece, adjust the diopter ring on left eyepiece to focus the specimen. Then repeat procedure for the right eyepiece.
• Adjusting Interpupillary Distance (Fig. 5)
  • Different users have different interpupillary distances (this distance is between the centers of the pupils of each eye). When the operator changes, it will be necessary to adjust the interpupillary distance.
  • While looking through the eyepieces, hold the left and right eyetubes of the viewing head and adjust the eyetubes by opening or closing them until the left and right fields of view coincide completely and you are able to see a complete circle.
• Installing or Removing the Reticle (Fig. 6)
  • Unscrew the reticle retaining ring 1 from the eyepiece (see Fig. 6).
  • NOTE: be sure to clean the reticle with a soft, lint free cloth or cotton swab dampened with a lens cleaning solution (available at camera stores – Care & Maintenance).
  • Insert the clean reticle into the eyepiece 2, then screw the reticle retaining ring back onto the eyepiece.
  • To remove the reticle, unscrew the reticle retaining ring from the eyepiece, carefully remove the reticle, and store the reticle in lint-free paper. Screw the reticle retaining ring back onto the eyepiece.
