The folder has a timestamp that doesn’t make sense, why?
- If the sensor is not connected to the tablet application at the start of data collection (i.e. when the sensor is off the charger) it will not be able to sync its internal clock with the tablet.
- Advise the study subject that if they see a blinking blue light on the sensor, they should connect to the tablet application to make sure the data collection start times are accurately recorded.
- The data should be examined to see if it looks like an expected set of data and is the expected amount of time for data collection.
- If the data looks valid, examine the upload time and/or collect additional information from the site to estimate data collection time.
