How to choose a lens
Lens A:
Focus range：12mm-320mm， Magnification：60-240x（with 33 times digital zoom, output to 28-inch HDMI monitor) Applications： observe whole size or part of coins, stones/stamps collect, circuit board observe, etc.
Pic 5 Use lens A to see a coin
Steps： In pic 5, it marked out which parts of the microscope are involved in each step.
- Install and fix lens A to the bottom of the focusing tube.
- Place the black or white backdrop board in the loophole on the stage, then place the coin on the
stage. - Bend the two goose-neck spotlights, and make sure the light shines on the coin.
- Lose the arm socket, locate the whole monitor part to the desired height, meanwhile adjust the height of the mechanical stage, and make sure the final object distance is within 12mm to 320 mm. The shorter the object distance is, the bigger the magnification is.
- Turn the focusing tube to get a clear image. Turn it clockwise to zoom in and the other way to zoom out.
- To observe part of the coin, please lower the arm height to shorten the object distance, then
turn the focusing tube to get a clear image. - The steps above can also be applied to observe plants, stones, etc.
Lens B&C
Lens B: Focus range: 7mm-8mm， Magnification: 1560-2040x (with 3 times digital zoom, output to 28-inch HDMI monitor)
Lens C: Focus range: 3mm-4mm， Magnification: 2760-4080x with 33 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 in each step.
- Install and fix the nosepiece set with Lens B&C to the bottom of the focusing tube.
- Place the translucent backdrop board on the loophole on the stage, and place slides on it.
- Remove the two USB spotlights.
- Lose the arms locker, locate the whole monitor part to the desired height, meanwhile adjust the height
of the mechanical stage, and make sure the final object distance is within 7-8mm(lens B). The shorter the
object distance is, the bigger the 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 the magnification is.
Digital zoom

Gridline Settings (remote needed)
Use “Up” and “Down” to choose among “Cross Line”, “Line”, “Direction”, “Location”, “Color”, and “Wide”. Use “Left” and “Right”(marked as a brightness +&- in pic 8) to change settings. The microscope can’t do this mission alone. The remote is needed. A cross line, as its name says, it’s a pair of vertical and horizontal lines located in the very middle of the
image.
When you turn on the function“Line”, there will be 8 lines showing up automatically(named 1 to 8). For each one, you could change its direction (“HOR” or“VER”, which stands for “horizontal” and “vertical”), position, color, and width. To delete unnecessary lines from the view, change its color to “TRANSPARENT”, see the following pic.
Output to external devices
HDMI output
- Firstly, make sure the external device is an actual, real FHD 1080P HDMI monitor; otherwise, the display resolution can not reach 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, and adjust the object distance and focus distance.
- When the microscope is connected to external devices, image data is transferred to the external device, so the microscope monitor displays no image.
- HDMI output supports photo capture, but not video recording.

FAQ
- Why does it say ‘ missing files’ during installation or the initialization procedure?
Please confirm that in the system, there is Microsoft. Net Framework 4.0 and Microsoft Visual C++ 2010 runtime. - 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 a ‘USB camera’ on the Andonstar 246S digital 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 the device changes. Let the system identify again. After it’s done, in the ‘Imaging devices’ there should have shown, the current USB camera device name, which is “USB Camera”. Then reboot the software. - Why is there a measurement error?
In order to get a more precise measurement result, you would need a more precise calibration. 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 when you set the calibration. - Why can’t the microscope be switched on？
Please connect the microscope properly, as in pic 4, and make sure it has a stable and strong 5V 2A power supply. If it doesn’t work, pin the reset holeont the back side of the monitor.
