Overview
Withings Smart Body Scale (Model WBS01) is a medical device designed for individual health monitoring. It provides measurements such as weight, body mass index (BMI), and body fat percentage using bioelectrical impedance analysis (BIA). The device is identified as a Body Composition Analyzer under the product code MNW and is a Class II medical device. It includes wireless connectivity features for a user-friendly interface and data tracking but is contraindicated for individuals with pacemakers or other internal medical devices.
Device and Technology
The WBS01 utilizes BIA technology, which quantifies body composition by transmitting a safe electrical current through the body. This current encounters different levels of resistance depending on the tissue type, which the scale then translates into body composition metrics like body fat percentage. Additionally, the scale has an 802.11 (Wi-Fi) module, allowing it to connect to the internet independently of its analysis functions. Despite the wireless capabilities, it operates primarily as a standalone body fat analyzer.
Key Functions and Features
Measuring Functions: The primary purpose of the WBS01 Smart Body Scale is to measure the user’s weight, BMI, and body fat percentage. The scale comes with a unit switch function for displaying weight in kilograms, pounds, or stones and pounds. It also offers an automatic recognition feature that identifies users based on their weight, albeit with a recognition tolerance of 6.6 pounds.
Interactive Operations: If multiple users have similar weights, the scale will present possible identities, with the user self-identifying by leaning to the left or right. Additionally, the scale includes a warning message function to notify users of low battery and instructs them to replace all batteries simultaneously.
Wi-Fi Connectivity: Wi-Fi enables the scale to integrate with the Withings web application, providing a complementary interface for viewing historical weight and body fat data. Users must enter personal information such as height, birth date, gender, and activity level to create a profile. This Wi-Fi connectivity ensures user profiles are accessible for each analysis.
User Experience: The WBS01 Smart Body Scale enhances the user experience with its simple profile creation process, interactive interface for data visualization, and easy-to-follow user manual instructions.
Safety and Effectiveness
The manual emphasizes the scale’s safety and effectiveness by ensuring that the Wi-Fi functionality does not impede the scale’s body analysis performance. The functions of analysis and connectivity are designed to operate separately, ensuring accuracy and reliability.
