Sensor Life
Sensor life measured the percentage of sensors being able to function through the intended 90 day durations of each
study. In the PRECISE II study, nine sensors did not function through the 90 day period. Function stopped at days
10, 30, 53, 67, 70, 80, 81, 83, and 85. The sensor failure on day 10 was due to a software anomaly that has since been
resolved. Overall, the analysis estimated that 91% of sensors remained functioning through 90 days. In the PRECISION
study, all sensors functioned through 90 days.
