Wearing & Replacing Watch Strap

Put the strap on with comfortable looseness to allow the skin to breathe and the sensor to function.
When measuring SpO2, avoid wearing the watch on the wrist joint, keep your arm flat, maintain a comfortable (appropriately tight) fit between the watch and the skin of your wrist, and keep your arm still throughout the measurement process. When affected by external factors (such as arm sag, arm sway, arm hair, and tattoo), measurement results may be inaccurate or the measurement may fail with no output.

You can tighten the watch strap during workout and loosen it afterwards. Tighten the strap appropriately if your watch sways on your wrist or fails to output data.

To change the watch strap, refer to the illustration below:

Note:
After the strap is attached, please pull the strap using appropriate force to ensure a secure attachment.
Avoid contact with liquid, as the leather strap is not waterproof. Switch to a fluororubber strap or a silicone strap when you cannot avoid such contact, for example, when swimming.

Activities and Health

PAI

PAI is an indicator of personal physiological activity. Based on heart rate data, daily activity intensity, and multidimensional and dynamic evaluation of personal physiological data, PAI is obtained through calculations by an algorithm. PAI does not rely on individual data categories alone. Therefore, it allows you to systematically and comprehensively understand your physical condition.
By maintaining a certain intensity of daily activities or workouts, you can obtain your PAI value. According to the results of the HUNT Fitness Study*, maintaining a PAI above 100 helps reduce the risk of cardiovascular death and increase life expectancy.

For more information, start the Zepp App and choose PAI cards > Q&A.
*The HUNT Fitness Study, a sub-project of the HUNT study, is led by Professor Ulrik Wisloff from Medical School of Norwegian University of Science and Technology. It has lasted for over 35 years, and involved more than 230,000 participants.

Activity Goal

The watch automatically records your activity data, including steps, calories, standing count, and distance. It also records the duration that heart rate is maintained within or above the fat-burning range as an index of fat-burning time.

1. Your daily activity goal consists of three parts, including Move ring (with target steps or calories), Fat burning ring, and Stand ring.

2. When a target is achieved, the watch vibrates to congratulate you.

Idle Alerts

To encourage you to have a certain amount of activity every hour when you are awake and reduce the harm caused by sitting for too long, the watch monitors your activity as you wear it.
If no activity is detected for more than 1 min at the 50th min of the current hour when you are properly wearing the watch, the watch will vibrate to remind you to do some exercise. After receiving an idle-alert, if you complete activities before the next hour arrives, the stand target of the current hour can still be achieved.

Enabling idle alerts:
Keep the watch connected with your phone, start the Zepp app, choose Profile > Amazfit GTR 2 > Notifications and reminders > Idle alert, and enable the function.

Heart Rate

Heart rate is an important indicator of physical condition. Highly-frequent heart rate measurement helps capture more heart rate changes and provide a reference for a healthy lifestyle.
To ensure measurement accuracy, you need to wear the watch correctly according to the instructions, and ensure that the part next to your skin is clean and free of sunscreen smear.

Heart Rate Alerts

You can enable the heart rate alert function, when you set the detection interval as within 10 minutes.

The watch vibrates when the alert value is reached and there is no obvious activity detected in the last 10 min.

Automatic Heart Rate Detection

1. Keep the watch connected with your phone, start the Zepp app, choose Profile > Amazfit GTR 2 > Health Monitoring to enable Automatic heart rate detection and set measuring frequency. Then the watch automatically conducts regular measurement of your heart rate at the set frequency and records your heart rate change throughout the day.
2. Heart rate can change dramatically when you are doing an activity. If you enable the Activity detection function, the watch will automatically increase the heart rate detection frequency to guarantee the accuracy of HR data during workouts.
3. The watch’s heart rate app allows you to view the heart rate curve and heart rate distribution throughout the day.

Manual measurement

1. To measure your heart rate manually when Automatic heart rate detection is not enabled, wake up the watch, press the side button to go to the app list, and swipe up or down to select the heart rate app.
2. You can set the heart rate app as a quick access app to facilitate heart rate measurement.

3. The watch only allows you to view the heart rate value measured this time. To view historical records, you need to synchronize data to the Zepp app.

Sleep

Sleep quality has an important impact on human health.
If you wear the watch while sleeping, it automatically records sleep information. You can synchronize sleep information to the Zepp app to view the sleep time, sleep stages, sleep score, and sleep suggestions.

Sleep Assistant

Keep the watch connected with your phone, start the Zepp app, and go to Profile > Amazfit GTR 2 > Health Monitoring to enable Sleep assistant for more accurate sleep information (REM sleep stage).

Sleep Breathing Quality Monitoring

Keep the watch connected with your phone, start the Zepp app, and go to Profile > Amazfit GTR 2 > Health Monitoring to enable sleep breathing quality monitoring. Then, the watch will automatically monitor sleep breathing quality when it detects that you wear the device during sleep.

SpO2

3. Place your arm on a tabletop or a stationary surface, with the watch screen facing up.
4. Remain still during measurement and focus on the measurement.
5. Factors such as hair, tattoo, shaking, low temperature, and incorrect wearing of the watch may affect measurement results, and even lead to measurement failure.
6. The measurement range of this watch is 80%-100%. This function is for reference only and should not be used as the basis for medical diagnosis. If you feel unwell, please seek professional medical advice.

1. Wake up the watch, press the upper button to go to the app list, and swipe up or down to select the stress app to view related information.
2. When Automatic stress testing is enabled in the stress app, stress measurement is performed every 5 min to show you changes in your stress. You can also keep the watch connected with your phone, start the Zepp app, and go to Profile > Amazfit GTR 2 > Health Monitoring to set this function.
