BLAZE HEART RATE

[amytaylorgj]

I just got the new fit bit blaze. As I was doing my workout today my heart rate never registered over one 30 bpm. When I took my heart rate manually it was over 170. Do I have a bad fit bit or is there a reason it would do this? Thanks

Have you followed the instructions on how to position the Blaze on your wrist and how to properly tighten the band?

[amytaylorgj]

Yes I have. Does having lotion on affect the heart rate reading at all?

@amytaylorgj it would if the lotion gets on or obscures the sensors, especially noting how sweat can have an impact.

Try running without lotion and see if there is a difference. Does it work as expected during normal everyday activities?

@amytaylorgj if the lotion did obsorb the light spectum the the Blaze uses, then in theory it could affect the reading

This is how sun tan lotion works,  it obsorbs the UV light, so that it doesn't teach the skin. 

Most lotions of they ate designed to obsorb Uv and not visable,  especially  red light. It would make the skin look pale removing all red. 

So unless the lotion was rock and stored onto the sensor,  a problem with sunscreen, let it absorb,  it should be ok. 

As @SunsetRunner stars it would not be to hard to ruin your own tests.
