（Pic 5 Use lens A to see a coin）
Steps：In pic 5 it marked out which parts of the microscope are involved to each step.
①Install and fix lens A to the bottom of the focusing tube.
②Place the black or white backdrop board to the loophole on the stage, then place the coin on the
stage.
③Bend the two goose-neck spot lights, make sure the light shines on the coin.
④Loose the arm locker, located the whole monitor part to a desire height, meanwhile adjust the height
of the mechanical stage, make sure the final object distance is within 12mm to 320 mm. The shorter the
object distance is, the bigger magnification is.
⑤Turn the focusing tube to get a clear image. Turn it clockwise to zoom in and the other way to zoom
out.
*In order to observe part of the coin, please lower the arm height to shorten the object distance, then
turn the focusing tube, get a clear image.

Steps：In pic 6 it marked out which parts of the microscope are involved to each step.
①Install and fix the nosepiece set with Lens B&C to the bottom of the focusing tube.
②Place the translucent backdrop board to the loophole on the stage, and place slides on it.
③Remove the two USB spot lights.
④Loose the arm locker, located the whole monitor part to a desire height, meanwhile adjust the height
of the mechanical stage, make sure the final object distance is within 7-8mm(lens B). The shorter the
object distance is, the bigger magnification is. Or if you want to zoom in even more, revolve the
nosepiece to lens C and make the object distance within 3-4mm. The shorter the object distance is, the
bigger magnification is.
⑤Turn the focusing tube to get a clear image. Turn it clockwise to zoom in and the other way to zoom

out. Or, we recommend users to gently adjust the stage height to get a clear image, this way causes
less shake.
*Lens B&C’s magnification is quite big, which requires a short object distance. Meanwhile, any
tiny movement or shake of specimen would be displayed as huge on the monitor, which requires
user to operate very carefully and patiently.

Output to external devices
◆HDMI output
•firstly, make sure the external device is actual real FHD 1080P HDMI monitor, otherwise the display
resolution can not reach to 1080P.
•Power on the microscope, and connect it to the HDMI monitor. The microscope has no built-in battery,
so please make sure the microscope stays powered on the whole time.
• Switch on the microscope, place the specimen on the base or the slide holder, adjust the object
distance and focus distance.
•When the microscope is connect to external devices, image data would transfer to the external device,
so the microscope monitor display no image.
•HDMI output supports photo capture, but not video recording.

FAQ
1. Why it says ‘missing files' during installation or initiator procedure?
Please confirm that in the system there are Microsoft. Net Framework 4.0 and Microsoft Visual C++ 2010
runtime.
2. The software works fine, but the software can not recognize the microscope.
Firstly, please make sure that you have connected the microscope to the PC properly and have chosen ‘USB
camera' on the microscope monitor. Secondly, if there is still no image, please check the ‘Device Manager' of
your PC, delete the previous USB camera from “image devices”, then rescan device changes. Let the system
identifies again. After its done, in the ‘Imaging devices' there should have shown the current USB camera
device name, which is “USB Camera”. Then reboot the software.
3. Why there is a measurement error? In order to get a more precise measure result, you would need a more
precise calibration. And when you apply a calibrator to measure a length, you need to keep the magnification
still, which means you need to keep the object distance still as when you set the calibration.
Why the microscope can’t be switch on？Please connect the microscope properly as pic 4, and make
