1. Connect the Ken-A-Vision product(s) in the USB port(s) of your computer.
2. Once the product(s) are connected, launch Applied Vision software on your computer.  A live camera view should appear.
3. Within the field of view of the camera or microscope place a good quality measuring tool.On the lower menu, select “Take a Snapshot & Annotate.”
   • For a camera, place a ruler of choice.
   • For a microscope, place a stage micrometer slide.
4.  A new window should appear and it should be labeled “Image.”
5. Select the second tab, “Measure.”
6. Now choose “Select Saved Scale” and you will see the model number of the T-19641C Digital Comprehensive Scope 2 microscope. 
7. So, I am on the 4x objective so I choose that scale by clicking on the correct model number T-19641C (4X)
8. To measure, hold down the mouse button and drag the line across, until you have measured a specified length then release the mouse button.
9. The line should appear orange if measured correctly.
10. In the lower menu, select “Perform Measurement.”
11. A new box appears named “Measure.”  The line you just measured on the image should be denoted in this box with a measurement.
12. If you wish to take another measurement, repeat the steps and the 2^nd measurement will be added right below the first measurement in the spreadsheet.
13. You have several options once you are finished measuring:Now, each of you received a Slide Micrometer with your digital scope and you do have the option to calibrate your own microscope and create a new scale. 
    • You can select, “Copy All Measurements to Clipboard.”  This allows you to take all the measurements and export them to an outside program such as Microsoft Excel.
    • You can select, “Write Last Measurement to Image”.
    • You can save the image or print the image.
14. Place the micrometer slide on the stage and focus in with the 4x objective.
15. On the lower menu, select “Take a Snapshot & Annotate.”
16. A new window should appear and it should be labeled “Image.”
17. Select the second tab, “Measure.”In the lower menu, select “Calibration” and a “New Scale” window appears on screen.
    • Now measure a denoted length on the micrometer slide.  I will measure 0.01mm or 10 Micrometers.
18. Name your new scale, the known distance, and what units you are working in.  When you are ready to save the scale, select “OK.”
19. To make sure your new scale is recorded, in the lower menu, select “Select/Remove Scale” and then select “Select Saved Scales.”  The new scale you just created should have a checkmark by it denoting that it is the scale in use.
20. Finally, if you wish to delete the scale you have just created, simply select “Select/Remove Scale”, select “Remove Saved Scale” and then select the scale you wish to remove.

Ken-A-Vision’s Sister Martina Rockers – Excellence in Teaching Award honors a STEM teacher, in middle or high school, who demonstrates excellence in STEM teaching and student-centered instruction. Started in 2003, the award is named after Sister Martina Rockers of Bishop Miege High School in Kansas City. In over 60 years of teaching science, Sister Martina inspired and challenged her students to learn in and outside the classroom.

 The Ken-A-Vision Rockers Award offers one award winner a trip to NSTA Nationals Convention, a cash prize and Ken-A-Vision products, a personalized engraved plaque, and many more benefits.

Ken-A-Vision will recognize the award winner at a meet and greet in Ken-A-Vision’s booth at NSTA Nationals Convention and be accompanied by Ken-A-Vision representatives to an all expense paid dinner.

Compound microscopes should generally be serviced after about 200 hours of use.  For most schools, this would be about every three years; possibly more frequent if the microscope is used multiple times each day.  Ken-A-Vision repairs their own microscopes and also has a nationwide list of science dealers who repair our microscopes.

Proper Quick Techniques

• Hold from base & carrying handle. 
• Use the provided dust cover.
• Do not store a microscope without any eyepieces, even if it is covered. This can allow dust to collect within the eye tubes, which can be difficult to clean.
  • If the microscope eyepieces must be removed, simply cover the tubes with caps or a plastic bag with a rubber band around the eye tube.
• Do not store your microscope in an area that has corrosive chemical fumes that can destroy lenses or metal parts.

Cleaning Microscope Eyepiece Lenses

• Never use sharp instruments or anything abrasive to clean the microscope lens.
• Clean the microscope eyepiece or the microscope objective lens:
  • Moisten lens paper with lens cleaning solution and clean the lens with a circular motion.
  • Dry the lens with a clean, dry piece of lens paper and when you are finished use an aspirator to remove any lingering dirt or particles.
• Determine if your microscope eyepieces need cleaning:
• • Loosen the small set screw for the eyepiece (if there is one)
  • Rotate the eyepiece in a circular motion while looking through the microscope
  • If there is a dust particle that rotates as you rotate the eyepiece, remove the eyepiece from the microscope and clean both sides of the lens with lens paper.
  • If you need to use any liquid for cleaning, distilled water is recommended.
  • It is not recommended that you take the eyepiece apart, as there are generally multiple lenses in the eyepiece and they can be difficult to put back together in the correct order.

Cleaning Objectives

• Determine which of your objective lenses need cleaning:
  • Take a clean blank glass slide and put it under your microscope.
  • Once the microscope is focused you should be able to move the slide and determine if the visible dust is moving with the slide or staying in the same place (which means the dust is on the objective lens).

• Cleaning immersion oil on the highest power objective lens (usually 100x)
  • Clean with a piece of lens paper, no cleaning solutions are needed.
  • Dust may build up on the lightly oiled surface so if you wish to completely remove the oil then you must use an oil soluble solvent.

• Use Naphtha, Xylene, or turpentine (use very small amounts on the lens paper).
• Do not use water, alcohol or acetone as the oil is insoluble to these solvents.

Mechanical Maintenance

• Each microscope comes with a user’s manual.
• Always consult this user’s manual before making any adjustments to your microscope.
• Never over-tighten or use force when performing any maintenance on your microscope.
• This can damage metal parts in the microscope.

1. First, gently close the iris diaphragm as far as it will go.
2. Turn the condenser knob until the condenser is at its uppermost position.
3. Next, turn the nosepiece to the intermediate (10x) objective and lower the lens to within 1 cm of the stage, watching from the side.
4. Then turn the rheostat (light dimmer switch) to the lowest setting at which you can see the light.
5. Center on your stage a slide (a letter e or thread slide works best). Bring the slide into focus with the coarse and fine adjustment knobs.
6. Now, lower the condenser slowly until you see granularity come into focus superimposed on the specimen slide. You are seeing the granularity of the ground glass diffuser covering the light source.
7. Now raise the condenser slightly until the granularity of the diffuser just becomes no longer visible. This will be your optimal condenser setting which is about 0.5 mm from the top of the stage.
8. Finally, open and close the iris diaphragm slowly, watching the changing quality of the image of the specimen.
9. When the iris is full closed, contrast is maximum and the chance for “false lines” is the greatest, but the “washout” of the image takes over, due to imperfections in the condenser.
10. Find a position, slightly opened, where the image is clear, bright, detailed and sharp. This is your optimal iris setting at 10x (usually the best setting is right in the middle of the iris diaphragm’s range.)

REMEMBER: You will have to change the iris diaphragm setting with different magnifications and with the various specimens you view.  You have now achieved “critical illumination.”
