[Diagnostic Devices](https://support.omply.com/en/diagnostic-devices?hsLang=en) November 5, 2026 # Pulse oximeter: guide and troubleshooting The pulse oximeter measures your blood oxygen saturation (SpO₂) and pulse from your fingertip. The device is the Lepu-Creative PC-60FW. It connects to your phone over Bluetooth and runs on two AAA batteries, which aren't included. ### How to use the pulse oximeter Take the measurement during your appointment with your doctor or right before it. That way your doctor is sure to get your own readings, not an earlier measurement taken by someone else, such as a family member. 1. Make sure your hands are clean and warm. Sit calmly for about a minute. 2. Open the oximeter from the hinged end. 3. Place it on your index or middle finger with your nail facing up and your fingertip in the center of the measurement area. 4. The device turns on by itself. Avoid talking and moving during the measurement. 5. The device beeps steadily, and the result is ready in under a minute. 6. The result is saved locally on your phone in the Omply app, and you can share it with your doctor from there. If you're in an appointment, your doctor sees it in real time. 7. Take the device off your finger. It turns off by itself. ### If something goes wrong - **The device won't turn on.** Replace the batteries and check that they're the right way around. - **The readings keep changing or don't appear.** Place your finger in the center of the measurement area again and keep your hand still. Warm up cold fingers. - **You're wearing nail polish.** Dark or metallic polish and artificial or gel nails can distort the result or prevent the measurement. Use a finger without polish, or remove the polish. - **The app shows Device not detected.** The oximeter is only on while your finger is in it. Place it on your finger and wait a moment. If it still won't connect, see [My device won't connect](https://support.omply.com/en/my-device-wont-connect.-how-can-i-fix-it?hsLang=en). - **The wireless icon doesn't appear on the device's display.** The device's wireless function may not be working. Contact customer support. If you won't use the device for a long time, take out the batteries. ### Instruction video and user manual - [Watch the instruction video (in Finnish)](https://support.omply.com/en/device-instruction-videos-in-finnish?hsLang=en#h_01KPN6RVS78MRK82HF8B7WN2GT) - [Quick guide (PDF)](https://support.omply.com/hubfs/User%20manuals/User%20Guide_Pulse%20Oximeter.pdf?hsLang=en) - [Manufacturer's user manual (PDF)](https://support.omply.com/hubfs/Oximeter-Manual.pdf?hsLang=en) ### Related articles - [My device won't connect.
