            DeviceMetric.measurementFrequency : The frequency at which the metric is taken
             or recorded. Devices measure metrics at a wide range of frequencies; for example,
             an ECG might sample measurements in the millisecond range, while an NIBP might
             trigger only once an hour. Less often, the measurementFrequency may be based on
             a unit other than time, such as distance (e.g. for a measuring wheel). The update
