HRM RUN not disconnecting after workout.

Markyz85

Have you had a conversation with Garmin Support?

Not yet, wanted to ask here first. But yesterday I tested another two (Polar H7 and Garmin Premium) HRM and with both OHR strated within minute or so after workout ended. So it seems to be the problem is in my old HRM RUN.

OK, I'll bite in for a strap HR monitor to work it needs to receive an electrical signal transmitted through the skin. Therefore, I'm not sure how your strap could report to your watch a HR of 209 BPM from the air.

This can happen sometimes when the electrodes are not touching your body but are in contact with something. In the past I observerd HR readings from external strap when the strap was for example placed in a wet bag (after a swim), or when I folded it and put into my trouser's pocket (made of polyester which tends to accumulate electrostatic charges).

But when I do take care that nothing touches the electrodes (usually I just stretch the strap on a flat surface with electrodes facing up - just to let it dry off after rinsing in water) the strap stops transmitting after a short period.

In the past I observerd HR readings from external strap when the strap was for example placed in a wet bag (after a swim)

This happens to me with my HRM Swim after use, I always assumed that the wet strap was causing it to think it was still attached to my chest. I have just got into the habit of disabling it on the watch after a swim to prevent the wacky readings.

When I’ve an activity selected my Garmin will connect to the strap as soon as it is wetted before I put it on. Usually shows around 70 bpm. After use, I always take the sensor module off then there is no detection. Obviously with the one piece straps this is not possible so I guess the only thing to do is to put them somewhere to dry.

Just an example why people like me think they have "the perfect watch" when it comes to continues HR readings between swapping OHR and HRMrun (new/red) for an activity. I took the strap off right after the activity. The only break in the curve is at 7am something when I took a shower which is like 1/2hr after the run. No need to switch off things or so, just leave the strap drying off on a hanger. Well, I should say I follow Garmin advise/manual to a) rinse thorougly after use and b) use soap after every 7th use.


A picture says more than thousand words, so here we go:

I started to have exactly the same problem... It started after update to recent beta 7.54 but maybe this problem was before and i didn't notice? anyway whenever strap is in range im getting crazy hr readings like 244 ish.... removing battery from the strap and putting back doesn't help. Neither reconnecting strap in settings... strap is still wet... maybe this is the reason? I have another new hrm tri (blue one). will test it later. I really hope it is just new software...

My 935 (and my 920, and 910 before it) will always connect to the HR strap as soon as I wetted it before putting it on AND an activity was selected - this triggers a search for 'live' sensors in the sensor pool. It drops the connection to the watch as soon as I exit the activity after saving and go back to the watch face. Thereafter, the OHR carries on for as long as I have it on. I have not seen any attempts to connect to any sensors when no activity is selected, even if I move the HR or reconnect the module or re-wet it.

That's my experience with the HRM-Run with the removable module on my 935.

Others are reporting similar with the newer one-pice straps.

Others are reporting problems.

Some questions:
What is common between the devices without the problem?
What is not common between the devices with the problem?
Does it happen all the time?
Has the problem been reported to Garmin Support?

In my case, I have a 'vanilla' device with no extras added. I just use as is out of the box. I'm on 7.10 as of this morning. I connect to GE on a computer at least once a week. Most of my uploads are BT through my iPhone X or iPhone 6.

OK, intrigued by the claims on this thread, I conducted an experiment last night.

I did an activty with the chest strap (HRM-Run) on, then saved it, and switched to the HR widget, which showed my HR as measured by the strap.

I then took the strap off and placed it down motionless.

* For 30 seconds after I removed the strap, the widget displayed my last recorded HR without variation.
* After 30 seconds, the HR widget showed "---" for my heart rate. Peeking under the wrist showed the OHR LED's were not active.
* After 2m 30s, the HR widget showed "measuring", then 5 to 10 seconds after that showed my heart rate, with the LED's being active.

Perhaps someone with an HRM-Tri or an HRM-Swim could replicate this process, and see if they get the same or a different result?

So I have a new 935 and HRM-Tri. I did my first run with it yesterday, with the HRM-Tri strap. I ended the run on my watch, removed the HRM-Tri strap, wiped it clean and let it hang on a hook in my gym. I then had intended to start a strength training workout, immediately following my run, but use the optical heart rate for training, b/c I do not intend to wear a strap for strength training activities.

I am not trying to tell you what to do, but the order you are wearing the strap to OHRM (Strap for running and OHRM for Strength) would be considered backwards. If anything the OHRM is "adequate" as an option for running, but a strap is going to give much better HR data (if using a HRM-Run/Tri also advanced running metrics and HRV). For strength training the OHRM is going to be next to worthless due to muscle flexion which is going to make the OHRM go nuts. I have seen gaps between a strap and the OHRM near 100 BPM difference, with the OHRM on the low end. I get that the strap might chafe or rub the wrong way lifting or doing transitional movements, but the reporting is night and day.

As I said above, not telling you what to do, but maybe try downloading: Auxiliary Heart Rate (apps.garmin.com/.../88ce4547-7d84-4289-b2c7-3e15ca00185f)

You will be able to see in both HR readings side by side after saving the routine. Try it, it might change your mind about wearing the strap during a strength routine.
