Frequently Asked Questions (FAQ) for SANWA SUPPLY LPE-05BK Digital Microscope (20–300×):

1. What is the SANWA SUPPLY LPE-05BK digital microscope?

The SANWA SUPPLY LPE-05BK is a portable digital microscope featuring a built-in 3-inch TFT LCD, integrated LED illumination, and a high-resolution CMOS sensor. It offers optical magnification from 20× to 300× and digital zoom up to 4×, enabling close inspection without a computer connection. It runs on a rechargeable lithium-ion battery, making it ideal for both field and laboratory applications.

2. What is the optical and digital magnification range?

It provides an optical zoom range of 20× to 300× and a digital zoom factor up to 4×. When displayed on its LCD, the working magnification effectively ranges from about 7× to 29×. Captured images at 5 MP resolution, when viewed on a 24-inch (1920×1080) monitor, appear enlarged by up to 380× relative to the actual sample.

3. Which sensor and image/video resolutions does it support?

It employs a 1/3-inch, 5.0 MP CMOS sensor. Still images can be saved at resolutions of 12 M, 8 M, 5 M, 3 M, 1.3 M, or VGA (640×480). Video recording uses AVI (MJPEG) format, with selectable resolutions from VGA to QVGA depending on settings and media capacity.

4. What image and video file formats are used?

Still images are stored in JPEG format for broad compatibility. Video clips are recorded in AVI (MJPEG), ensuring easy playback on most Windows systems without additional codecs.

5. How is the display designed for viewing?

The microscope features an integrated 3-inch TFT LCD screen. The liquid-crystal panel can rotate to adjust the viewing angle without moving the entire unit, enabling comfortable observation of specimens in tight spaces.

6. How do I store and transfer captured data?

Images and videos are saved to a microSD or SDHC card (up to 32 GB, sold separately). You can also connect the microscope to a PC via USB for direct file transfer. A video-out terminal lets you feed live images to an external monitor or recorder.

7. What is the power source and battery life?

Power comes from a built-in lithium-ion battery. With the LEDs on, it runs for up to 90 minutes; with LEDs off, it can last approximately 180 minutes. Charging via the supplied AC adapter or USB cable takes about 3.5 hours to reach full capacity.

8. How do I focus and operate the microscope?

Insert and format a microSD card, then power on the unit.

Select the desired optical zoom (20×–300×) and optional digital zoom (×1–4).

Rotate the LCD panel for the most comfortable viewing angle.

Position the lens 8–12 mm from the specimen and adjust focus until the image is sharp.

Press the capture button for still images or the record button to start/stop video.

9. What accessories are included in the package?

The LPE-05BK kit contains the microscope body, lithium-ion battery, AC adapter, USB cable, video cable, cleaning cloth, carrying pouch, and a dedicated stand. The stand secures the microscope for hands-free, stable imaging.

10. What are common applications for this microscope?

Typical uses include PCB and solder joint inspection, crack and surface defect analysis on metals or plastics, label and print verification, basic biological specimen observation, and instructional demonstrations. Its portability and self-contained display make it well suited for both classroom and industrial environments.

11. How should I clean and maintain the device?

Gently wipe the lens with a soft microfiber cloth or lens paper. Avoid strong solvents or abrasive materials near the LEDs and electronics. Store the microscope in its pouch in a dry, cool area, and remove the battery if it won’t be used for an extended period.

12. What troubleshooting steps can I try?

No power/display: verify the battery is charged and properly seated.

Memory card not recognized: reformat to FAT32, then reinsert.

Poor focus: ensure the lens-to-sample distance is 8–12 mm and recalibrate focus points.

Files won’t save: check free space on the card and confirm the correct save format.

13. What warranty and support options are available?

The LPE-05BK includes a 12-month manufacturer’s warranty. Please contact QTE Technologies (qtetech.com/en)
