How to choose lens
Lens A：
Focus range：12mm-320mm，Magnification：60-240x（with3 times digital zoom,
output to 28inch HDMI monitor)
Applications：observe whole size or part of coins, stones/stamps collect, circuit
board observe etc.
6
（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 above can also be applied to observe plants, stones etc.

Lens B&C：
Lens B: Focus range: 7mm-8mm，Magnification: 1560-2040x (with3 times
digital zoom, output to 28 inch HDMI monitor)
Lens C: Focus range: 3mm-4mm，Magnification: 2760-4080x (with3 times
digital zoom, output to 28 inch HDMI monitor)
Applications: Microscope slides etc.
（Pic 6 go with Lens B&C）
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
8
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.
4.
Why the microscope can’t be switch on
？
Please connect the microscope properly as pic 4, and make
18
sure it has stable and strong 5V 2A power supply. If it doesn’t work, pin the reset hole at the back side of the
monitor.
5. Why can’t I get a clear image?Please confirm the illumination work properly, and shine directly to the
surface of the specimen. Adjust the height of the boom arm, or the secondary bracket lift to change the
distance from the lens to the specimen, and turn the focusing tube properly. If the image is still blurry, please
clean the bottom of the lens use a piece of clean and soft cloth.
6. Why the setting changes can’t be memorized? After changing settings, press and hold the button on the
monitor to switch off the device. DO NOT cut off the power supply directly or use the dimmer cable to switch
off the device.
7. Why the microscope reboots repeatedly? Please check the if the cable connection is firm and if the
power supply is stable and strong enough. Please check your power adapter is high quality 5V 2A.
8. Why it shows “card error” or “card is full” after inserting memory card to the device. Please format the
card after insert it into the device.（Format steps refer to chapter “Save files to micro SD card”)
