Troubleshooting

Having trouble with some aspect of using ithlete?  Perhaps one of the headings below describes the problem and possible solutions. The ithlete Users Guide is also a great resource.

No heart rate signal getting picked up. The heart does not pulse after pressing Start and the two indicators at the top of the screen stay red. Things to check:

  • The receiver is pushed all the way into the phone and is not blocked by a case or cover. It has a firm 'click' when seated correctly.
  • The chest strap is a compatible type (see Equipment tab), that the skin contacts are moistened and that it is tight without being uncomfortable
  • The ithlete logo on the receiver is facing forward and that the receiver is no more than 8-10" (25cm) from the center of the chest strap

Unexpected or inconsistent readings. You get HRV readings that are much higher or lower than you were expecting, or inconsistent readings.

  • If the 'Pulse' or 'Valid RR int' indicators at the top of the screen turn red more than once or twice during the measurement, it is likely that the chest strap is not tight enough, the skin contacts are not moist enough, or the chest strap (or its battery) is nearing the end of its useful life.  
  • If the HRV number decreases and / or the resting HR increases during multiple readings, then you are not relaxed enough. HRV is a sensitive measure of stress, whether physical or mental, and anxiety about the HRV reading will lower it. Some people like to do their measure as soon as they get out of bed, whilst others prefer to walk around, or do some light stretching as part of their morning routine, then do the measure. The way you breathe will also affect the HRV reading. Breathe in time with the lungs, focus on the flow of air in and out of your nose & mouth. Never force your breathing.
