stored data includes: start time; stop time; starting pressure; ending pressure;
average, minimum, and maximum flow rate; error status, and elapsed time. The
entire data set can be downloaded through the jump drive by inserting the drive in
the USB port and pressing the Store button. The file names on the jump drive are
unique and previously stored files do not have to be deleted before storing new data.
The data file name is the port or channel number and the date/time when the data
was written to the jump drive. An example of a typical data file is shown here:

Data for each port is saved until the port is sampled again. The new data is stored
in the location of the previous data. All data can be erased after a sampling
sequence by answering “Yes” to the query that appears when exiting the Data
screen.
The Next button on the 8001 Data screen will advance to the next data screen or
Exit can be used to return to the main screen.
