Your Digital YolkFan™ device may have gotten stuck. To fix the device, follow the suggested solutions below.

• Make sure your Digital YolkFan™ is not plugged in while scanning. To fix this issue, unplug your device and then reset it by gently pressing a paperclip in the small hole on the top of the device.
• It is a best practice to also allow a scan to complete before changing screens or apps.
• “Mashing” buttons on the app can sometimes cause issues.

• Have you tried charging the device? Use the included USB charging cable with any standard USB charger. A full charge shouldn’t take more than three hours.
• Don’t use your Digital YolkFan™ while it is charging.
• Reset your Digital YolkFan™ using the reset pin hole.
• Hard close the iOS app. (GUIDE)
• Distance yourself from other Digital YolkFan™. Sometimes you might inadvertently be connecting to a different Digital YolkFan™.
• Place your Digital YolkFan™ directly next to your phone. This will increase the signal strength and insure that the correct device is at the top of the Bluetooth list.

Insert a paper clip into the hole on the top of the Digital YolkFan™ unit. Push gently to reset the device – the light should be off now.

• The colors represented on your screen are back illuminated and use the RGB color system. Although the colors may not be true to life, the DSM YolkFan™ number will be correct.
• Please make sure you are scanning your yolk correctly and it is fully sealed under the yolk adapter. Do not differ from the procedure laid out in the guide above.
• Please make sure you are using the yolk adapter. The Digital YolkFan™ is calibrated for use with the adapter. Scans will be incorrect if the adapter is not used.

• Please make sure you are using the correct application when scanning yolks. Download the Digital YolkFan™ App for your smartphone or tablet below.

• It is also possible that your yolk is off the scale of the Digital YolkFan™. In this case  “1-” or “16+” will appear on the screen.

All Digital YolkFans™ are calibrated and tested in-house to ensure high accuracy and reproducibility, and unfortunately there is no way to re-calibrate the device outside of our facilities. However, all components in the Digital YolkFan™ were specifically chosen for their stability and our testing shows that reading consistency will be drift-free over time.

Experiencing a slight difference between Digital YolkFan™ readings and paper DSM YolkFan™ “eye-test” readings is expected. Due to the subjective nature of the paper DSM YolkFan™, a difference of +/-1 is well within the expected range.

If you are consistently experiencing a large difference between measuring methods, it may be due to an error in scanning procedure. Please ensure you are following the scanning procedure above.
