Hello! I have been downloading heart rate data from my sports activity through exporting it in the csv format. I realised that there are some periodic segments of data cells that are blank, despite putting on the wristwatch firmly according to the user manual. The watch sensor area was also clean as well. May I know what could be the cause of this? Or is this normal?

    It is normal. Due to the watch shifting or light momentarily getting under the band or a host of other reasons it may lose signal for a second or so every so often. It should have no impact on the overall HR average as it is for such a minimal amount of time.

    I hope this helped answer your question. If so, please mark it as a solution so others can look for it if they have the same question.
