I recorded some data and uploaded it to the computer (PC). But the only data I see in the file is date/time and duration. There is absolutely no actual oxygen data in the graph or on the tabular printout. Has anyone else had this problem? Thanks.
And BTW, I also have a non-recording oximeter. That one measures my resting level at between 96-97, which matches the gauge in my doctor's office.
The CMS50D+ reads a full 2% low every time (94-95). Clearly there's a calibration issue with the consumer devices.
Are you sure you had the record off? If you turn it back on all you'll get the date and time with a short duration and no data. Turning it back on erases all the data previously recorded.
The 50D+ doesn't have an onboard clock. Did you assign the correct starting time and date to the downloaded data? If you used the SpO2 Assistant, you can use the data file that the software downloaded.
The way I remember the technical data that accompanied the CMS-50's it stated that the accuricy is +/- 2%.
Statistics prove that people who have more birthdays live longer.
