Problems during analysis

Unable to Capture Images (black screen)

Look for a small red indicator light at the back; it should illuminate once you connect the microscope to a power source (mobile device or laptop).

• Ensure the cable is properly plugged into the back of the microscope.
• Test with another phone or tablet.
• Try to reboot the tablet. This might help if the camera is being used by another software.
• If available, try using another cable for connecting the microscope.

A Dark Spot Can Be Seen on the Live Image

If you can consistently see a dark spot, even when the sample chamber is moved, the optics of the device are probably dirty. Please clean the device.

Flickering Image in the Mobile App

If the image is flickering in the mobile app, try enabling the low-resolution option. If the issue persists, it’s possible that your device may not be compatible with the app (check out our Device Compatibility page). In such cases, we recommend giving our Web App a try instead.

Dark Images

If your images appear excessively dark, consider the following steps:

• Verify lighting settings: Ensure that your lighting settings are configured correctly. Select the ‘brightfield’ option for optimal results.
• Seek assistance: If you’re uncertain about how to adjust the settings to achieve the best image quality, don’t hesitate to reach out to our support team ([email protected]) for guidance.

Sharpness Indicator Issue in the Mobile App

If you’re experiencing difficulties with the sharpness indicator in the mobile app, we suggest restarting your mobile device.

Recognition Doesn’t Work for Microscope Camera

If you’re encountering issues with the recognition for the microscope camera, consider these steps to improve accurate detection:

• Ensure correct calibration: Make certain that your microscope camera is properly calibrated for the used microscope and magnification. Check out this article on how to calibrate the camera.
• Capture images outside the grid: After calibration, it’s advisable to capture images outside the grid area. The recognition algorithm doesn’t rely on the grid lines, and cells directly on the lines may not be detected, depending on whether the hemocytometer is new or has already been used multiple times.

Data is Not Uploaded

The app automatically checks the quality of the data network. If it detects no connection, or one of insufficient quality, the message “Waiting for a better network connection” will appear. The data for analysis will not be uploaded to the server until a better connection can be established. In this case, please check your Internet connection.

If there is an error during the transfer of data (e.g. because the network experienced a short outage), the message “Network error. Please resend your analysis” will appear. By pressing the „Retry“ button, you can resend the request to the server.

Results Concentration is Outside of the Recommended Area

Should the images captured have more or less cells than the recommended 5-100 cells per image, this can reduce the accuracy of the measurement. The dilution of the sample should be adjusted before repeating the analysis.

Many Cells are Not Correctly Recognized

This may occur for several reasons:

• The cells were not focused properly, before images were recorded.
• The optics and/or the camera is dirty.
• The yeast in the sample chamber was not allowed to settle for at least 1 minute after loading.
• The sample chamber was not properly cleaned after a previous analysis.
