78 CHAPTER 7  DATA COLLECTION

Note

If your sensor experienced power cycles during the study, it may have been impos-

sible for SmartSensor Manager to determine the timestamp of some of your inter-

vals. The timestamp entry for these intervals will appear blank. If you have detailed

knowledge about the length of the study and when the power cycles occurred (and

for how long), you may be able to reconstruct the unknown timestamps. Periodic

connection to the sensor is recommended in order to resynchronize the sensor time

in case of a power cycle.

Interval Data Buers

e second section of the download screen is Interval Data Buers. is section has two

options, View Data Buer Status and Erase Data Buers.

Selecting View Data Buer Status takes you to the Interval Data Buer Status screen; see

the Data Collection Setup section of this chapter for more information.

Note

If you are not sure when your storage space will completely ﬁll up with data; you can

click on the View Data Buer Status button and monitor its progress. You can also

look at the Flash Storage Time entry on the Data Collection Setup screen to see how

long you have before the ﬂash memory ﬁlls up. Multiply the percentage of remaining

storage space by the total Flash Storage Time to approximate the remaining amount

of time before the storage space will completely ﬁll up.

Selecting Erase Stored Data clears the sensor’s memory and starts fresh. If the storage

space is full, data must be downloaded or erased in order for the study to continue.

Note

If intervals expire during (or immediately after) your download, you will be prompted to

download the new intervals before you erase. If you are presented with the option to

download and erase, it is recommended that you do so in order to prevent losing data.

Data Logs

Going to File > Data Logs . . . allows you to create new data logs, open existing ones, and
