Heart rate measurement
• To guarantee a more accurate heart rate measurement, wear the watch correctly and
ensure the strap is fastened. Make sure that your watch is secure on your wrist. Ensure
that the monitoring module is in direct contact with your skin without any
obstructions.
Individual heart rate measurement
1 Open the Health app, touch Devices then your device name, go to Health monitoring >
Continuous heart rate monitoring, and disable Continuous heart rate monitoring.
2 Access the app list and select Heart rate to measure your heart rate.
• This measurement may also be aected by some external factors such as low blood
perfusion, tattoos, a lot of hair on your arm, a dark complexion, lowering or moving
your arm, or low ambient temperatures.
• Your watch can measure heart rates between 37 bpm and 209 bpm.
Heart rate measurement for a workout
During a workout, the device displays your real-time heart rate and heart rate zone, and
noties you when your heart rate exceeds the upper limit. For better training results, you are
advised to do a workout based on your heart rate zone.
• Heart rate zones can be calculated based on the maximum heart rate percentage or HRR
percentage. To choose the calculation method, open the Health app, go to Me > Settings >
Workout settings > Exercise heart rate settings and set Calculation method to either
Maximum heart rate percentage or HRR percentage.
• If you select Maximum heart rate percentage as the calculation method, the heart
rate zone for dierent types of workout activities (Extreme, Anaerobic, Aerobic, Fat-
burning, and Warm-up) is calculated based on your maximum heart rate ("220 minus
your age" by default).
• If you select HRR percentage as the calculation method, the heart rate interval for
dierent types of workout activities (Advanced anaerobic, Basic anaerobic, Lactic
acid, Advanced aerobic, and Basic aerobic) is calculated based on your heart rate
reserve (HRmax - HRrest).
• Heart rate measurement during a workout: The real-time heart rate can be displayed on
the device when you start a workout.
