To process the one-tap measurement, please wear the watch tightly at one finger-width from the wrist, and keep your arm still for best results. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement.
To measure SpO2, please wear the watch tight at one finger-width from the wrist and keep your arm still for best results. All-day monitoring of SpO2 needs to be enabled on the watch or in the Zepp App. SpO2 alerts are sent if the detected rate is too low compared to the preset value, which needs to be set in the Zepp App, at a minimum of 80%. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement.
The 24-hour heart rate monitoring feature requires the user to enable Auto Heart Rate Monitor in the Zepp App, and the minimum value can be set to 1 minute. Abnormal heart rate alerts and the preset value need to be set in the Zepp App.
The HUNT Fitness Study indicates that people who maintain a PAI score of 100 or higher show lower risk of hypertension, heart disease, and type-2 diabetes. HUNT Fitness Study: This study was conducted by Professor Ulrik Wisloff of the Faculty of Medicine, Norwegian University of Science and Technology. It lasted for more than 35 years and had more than 230,000 participants. To use this function, all-day heart rate monitoring must be enabled.
Sleep monitoring can record night sleep and naps that last more than 20 minutes. Any sleep period that starts or ends between 10pm-8am will be recorded as night sleep, and if you fall asleep within a 60-minute window at either side of your night sleep period, it will also be recorded as night sleep. Sleep recordings that start or end over 60 minutes outside your night sleep period, and that do not overlap the 10pm-8am timeslot at any point, will be recorded as a nap.
The 24-hour stress level monitoring needs to be enabled on the watch or in the Zepp App. Alerts for high stress levels are based on the preset value, and prompts for the breathing exercise need to be enabled on the watch.
The accuracy and sensitivity of the workout recognition feature varies from person to person, and are related to the posture and proficiency of the user during their workout. Short workout duration or frequent changes in posture may not trigger the automatic recognition feature. When you are driving a car or taking a bus, or taking part in other such activities, accidental recognition may be triggered if these activities are particularly similar to the selected workout mode. When you are conducting outdoor activities, if the GPS signal is poor or the AGPS data information has not been synchronized with the mobile phone for an extended period, these outdoor activities may be assessed as indoor activities.
Swimming Stroke Recognition includes: Freestyle, Breaststroke, Butterfly-stroke, Backstroke, and Medley.
Indoor positioning services are not supported. Positioning speed and accuracy may be affected by the surrounding environment.
Virtual Pacer is only compatible with Outdoor Running and Treadmill sports modes.
According to the ISO 22810-2010 standard, the Amazfit GTR 3 achieves a rating of 5 ATM, for a water-resistance of up to 50 meters, and is therefore suitable for splashes, snow, showering, or swimming. It has passed third-party testing conducted by Bureau Veritas, and the report number is XRX-ESH-P21041179. Remove the watch when taking a hot shower or trip to the sauna, since too much steam can affect the seal and make it less water-resistant in future. Do not wear the watch with a leather or metal strap when swimming - when preparing to swim, change to a fluoroelastomer strap or other suitable type.
