[ASUS VivoWatch 5 AERO] Monthly Calibration to Maintain Accurate Pulse Transit Time Index (PTT)

Monthly Calibration to Maintain Accurate Pulse Transit Time Index (PTT)

The ASUS VivoWatch utilizes your pre-entered personal information, such as gender and age, as a base and fine-tunes the Pulse Transit Time Index calculation using AI and advanced algorithms.

For the most accurate readings, it is recommended to calibrate the ASUS VivoWatch 5 AERO once a month using a trustworthy device.

By inputting high and low values into ASUS HealthConnect, the ASUS VivoWatch 5 AERO software is supplied with comparison parameters, enabling its algorithms to stay in tune with the wearer's condition and offer the most precise PTT readings.

How to Calibrate Pulse Transit Time Index (PTT)

1. Open the ASUS HealthConnect App and access the calibration: Devices > Pulse Transit Time Index Calibration.

2. Read the Pulse Transit Time Index (PTT) calibration instructions and input the "high value" and "low value" obtained from a reliable device in the dialog box. After pressing "Understood," it will be transmitted to the ASUS VivoWatch.

3. Next, perform a Pulse Transit Time Index (PTT) measurement on the ASUS VivoWatch 5 AERO. The calibration of the PTT will be completed after the measurement is finished.

4. To ensure data accuracy, calibration the Pulse Transit Time Index (PTT) once a month.

Consequences of Not Calibrating Pulse Transit Time Index (PTT) Regularly

Prolonged use of the ASUS Health Band without regular Pulse Transit Time Index (PTT) calibrations may cause the device to fail to compare parameters. The user may still be able to perform Pulse Transit Time Index (PTT) measurements, but the readings may be less precise.

For Best Results Have Only One User Per ASUS VivoWatch

The Pulse Transit Time Index (PTT) readings from the ASUS VivoWatch are generated by gathering signals from the VivoWatch sensor and incorporating personalized user information. AI and predictive algorithms then process these readings. The accuracy of PTT may fluctuate based on factors such as the frequency of wear, calibration, and duration of use.

Reset ASUS VivoWatch to Factory Settings Before Transferring to Another User

It is essential to remove personal data from the ASUS VivoWatch 5 AERO before transferring ownership to another person. Having incorrect personal information settings, such as gender, age, height, weight, and dominant hand, can impact the accuracy of Pulse Transit Time Index (PTT) measurements.

Before transferring ownership of the ASUS VivoWatch 5 AERO to another person, it is essential to reset the device to its original factory settings. Only after the device has been initialized and calibrated can it accurately measure the Pulse Transit Time Index (PTT).
