The study has the following objectives:
Objective 1: investigate ease-of-use associated with the CoVa Monitoring System: determine if subjects could use the test device on a daily basis, and if the components of this system (Sensor, Gateway, Web-based System) were indeed operational
Objective 2: determine if daily application of the Sensor's adhesive Electrodes resulted in any skin irritation
Objective 3: determine that the long-term reproducibility of measurements made by the test device is as good or better than the long-term reproducibility of the reference device
