Introduction
Thank you for purchasing the Comparison Scope 2. This is the perfect
classroom microscope for forensics and comparative sciences with the
ability to compare two sides, side-by-side. The microscope has upper
(incident) and lower (transmitted) ED light to view microorganisms
separately in a full-field or together in a split screen with high-quality
optics that will magnify 20-400 times and independent coaxial focusing
on each microscope base.

Microsco e Set-u Guide
The Comparison Scope 2 compound microscope can be set up in a
matter of minutes. To get the most out of this amazing teaching tool,
follow these step-by-step instructions:
1. Remove each microscope base from the package.
2. Remove the plastic bag and plastic coverings from
the objective lenses and eyepieces.
3. Place each microscope, with the arms of the
microscopes toward the back, on a flat, firm
surface with the “ ” microscope on your left and the
“R” microscope on your right.
NOTE: The serial numbers are located on the bottom base, designated
with an (left base) or R (right base).
4. Remove the bridge assembly and Seidentopf binocular
head.
5. At the top of the head socket of each microscope base,
find three screw holes.
6. Remove the “safety screws” in each hole using a small
screwdriver.
7. Underneath the “safety screws” there are set screws.
8. Using the provided small Allen wrench, turn
counterclockwise two or three full turns, until flush with
the inside rim of the head socket.
NOTE: The points of these screws are initially visible, turn the screws
until they disappear.
9. Place the bridge onto the two microscope bases with the
Ken-A-Vision logo facing towards you.
10. Tighten the set screws so the bridge is locked tight, and
return the safety screws over the set screws to prevent
tampering.
11. Remove the dust cover from the bridge assembly head
socket and turn the set screw on the right side
counter clockwise until the screw tip is flush with the wall
of the head socket.
12. Place the Seidentopf binocular head into the socket,
sliding in from the right, until it is flush in the socket
opening. Tighten the set screw.
13. Insert the eyepieces into the eyetube bodies.

14. Check the coarse focus knob on either side of the main
body support of each microscope. The coarse focus
knobs should turn easily.
NOTE: The stage should move freely up and down the main body
support when focusing. When you release the knob, the stage should
remain stationary, and not slide down the post on its own.
15. To operate the cordless feature of this microscope,
immediately plug in each microscope base to charge for
eight (8) hours.
a. Plug in the two (2) round pin adapters from the
power supply to the back of each microscope.
b. Connect the opposite end to a Ken-A-Vision
multicharger (Part # SCGN061) or an 110V
(220V international) electrical outlet.
NOTE: With one eight (8) hour charge, you can use the microscope for
up to forty (40) hours of continuous operation. The cordless microscope
can also be operated with the cord plugged into a power source.
c. When not in use, plug the microscope into a
Ken-A-Vision multicharger that will automatically
stop charging once the microscope is fully
charged to keep it at the optimal full charge for
longer battery life.
d. Should you need a replacement power
supply/charger, or new specialized,
rechargeable batteries (Part # VFBATBU5),
contact your nearest Ken-A-Vision dealer.
16. To turn on the ED lights, locate the power switch on the
right back side of each microscope base.
NOTE: The switch on each base is a double switch, with the middle
position being OFF.
17. Pushing the right side of the power switch controls the
bottom (transmitted) light for viewing microscopic
specimens.
18. Pushing the left side switch controls the upper (incident)
light for viewing opaque microorganisms.
19. The X-axis knob located below the Seidentopf binocular
head is set for split screen viewing.
NOTE: If you roll the X-axis knob, you can view the left side microscope
separately and roll the opposite way to view the right side microscope
separately.

Troubleshooting
This section provides many useful tips on how to solve common problems
while setting up or using the Comparison Scope 2:
I can’t see an image. I only see a partial image.
• Check to see if the power supply is plugged into an
electrical outlet or the battery is charged if using
cordless.
• Check to see if the ED lights are turned on by switching
the power button on the back of each microscope, right
or left. A red indicator light should glow if the ED lights
are on.
• Check to see if the objective lens is clicked into place.
• Adjust the amount of light controlled by the dimmer
switch (rheostat). Turn clockwise to increase the intensity
of light and counterclockwise to decrease.
It is difficult to get an image in focus.
• Adjust the coarse focus knobs slowly.
• Check to see if the objective lens is clicked into place.
• Check to see if there has been damage to the objective
lenses or eyepieces. If the lens/eyepiece is dirty, use lens
paper and distilled water to rub gently clean.
NOTE: Never rub the lens/eyepiece when it’s dry. This can cause static
charge that will attract dirt.
