It is a wearable, battery-powered device which enables the continuous monitoring and on-demand spot check measurement of photoplethysmography (PPG), electrodermal activity (EDA, bioimpedance-based), skin temperature, electrocardiography (ECG, biopotential based), and motion/activity (based on a 3-axis accelerometer). It allows for synchronized, multiparameter data storage on internal memory for later data retrieval and offline analysis and/or live monitoring on a PC (Windows® OS) or Android or iOS-based device. PREPARING THE VSM WATCH Before using the VSM watch, proper preparations must be made. Ensure the battery of the watch is charged and the WaveTool program for PC is successfully installed. See the Powering Up the System for the First Time sections for installation instructions. The watch firmware must be upgraded using the VSM WaveTool.
