Chest strap stays connected after activity. Results in high readings.

Hi,

I use a Garmin HRM-Run strap during activities. This gives me all the running dynamics and appears to be a bit more accurate than the optical HR.

However, when I finished my run and remove the strap from my chest. It keeps reading values from the chest. Even when I am just in the home screen of the watch. This results in very high readings (240+).

I have to manually disable the strap in the settings for the watch to disconnect and return to normal readings via the optical on-wrist sensor.

Is this normal behaviour?

Thanks!

    (I use a different brand strap, so - not sure this question applies to the HRM-Run, but here you go) Do you disconnect the hr 'module part from the strap? If you aren't doing that, you'll see the situation you're experiencing. Be sure to unsnap the module from the strap....

    Hi,

    The HRM-Run doesn't have a detachable module. So the strap just keeps sending signals to the watch even when it's removed from my chest.

    With my FR630, external HR straps were only connected when in activity (e.g. run, bike) mode. The FR645M apparently allows you to connect a strap in normal activity tracking mode.

    Workaround for now is to manually disconnect the strap in the settings. This will cause the strap to turn off after a while because it has lost connection with the watch.

    It also happens to me with the 645M, once the activity is over the external band must be disabled, these watches have a lot of bugs

    I have a 645M and since I use a different brand of strap (a Wahoo TickrX) that has the module able to be unsnapped from the strap part, I don't have that issue. When I finish an activity, I take off the strap, then disconnect the module from the strap. No problem. :)

    Hi Neil, so apparently the Wahoo turns off when you unsnap the module. Does the Wahoo supports running dynamics like the HRM-Run does?

    well I can't answer that fully because I use the strap only when biking. When I'm running I use the RD-Pod to get all those same running dynamics, and I use the wrist HR only. In checking their website, looks like the TIckrX gives cadence, ground contact time and vertical oscillation. Not the rest of the stuff like L/R balance and such. You might try the RD-Pod to get all the stuff you want - I find the wrist HR to be VERY accurate, for me anyway....

    Just as a data point, I use the HRM-Dual with my FR645 and do not encounter the strap staying connected once I have saved and exited the activity on my FR645.

    I have the earlier black-strapped HRM-Run with running dynamics, and I don't have this problem either. The transmitter does detach, but I leave it on unless I'm washing the strap. Electrolyte buildup could cause phantom readings.

    I had this exact problem when my HRM-Run was about 13 months old. It kept this up for a little while and then started easily losing connection and then stopped connecting altogether. Tried several fixes and nothing worked. Purchased a Polar strap, which does not support running dynamics, but it works. The other option was to plan on buying a new HRM-Run yearly.

    One option for you, depending on the watch you have, could be to use the RD-Pod to get the various running dynamics data. Basically the RD-Pod was created to fill the gap of users needing that advanced running data, but who were using wrist-based heart rate. (think of the RD-Pod as like the HRM-Run, but without the HRM part hahah).I use the RD-Pod along with my 645 and find the combo to give me all the data I need. Good luck!
