Versa 2 won't track my heart rate accurately

[KirstenH22]

Hi, so I've noticed for over a month my fitbit versa 2 has a error with the heart rate tracking. It keeps saying my heart rate is over 100. That can't be right. How do I fix it.

Hi there, @KirstenH22. Welcome to the Community Forums. Thanks for the details provided in your post about the issue with your Versa 2. I understand where your concern is coming from. 

As with all heart-rate tracking technology, accuracy is affected by personal physiology, device location on your arm, and type of movement. For a more accurate heart-rate reading:

• Wear your Fitbit device on top of your wrist, and make sure the back of the device is in contact with your skin.
• When you’re not exercising, wear your device a finger’s width above your wrist bone.

• During exercise, wear your device a bit tighter and higher for an improved fit. The band should be snug but not constricting (a tight band restricts blood flow, potentially affecting the heart-rate signal). Many exercises such as bike riding or weight lifting cause you to bend your wrist frequently, which could interfere with the heart-rate signal if the watch is lower on your wrist.
