Calibration and Bump Test Records • 70
The files that an SDM-E2 saves to a USB flash drive are structured so that they can
be imported into a database controlled by the Single Module Data Viewer Software.
See “Importing Files Into the Database” on page 73 for instructions to add files to the
database.
Bump Testing or Calibrating and Saving Files To a Flash Drive
Multiple Times In One Day
The SDM-E2 assigns file names to calibration and bump test record files based on
the day of the most recent calibration or bump test record saved in the docking
station’s memory. If a copy operation is performed, then additional bump tests or
calibrations are performed, and another copy operation is performed with the same
flash drive all on the same day, the existing file on the flash drive from the first copy
operation will be overwritten by the file from the second copy operation because its
name will be the same as the new file. In this case, no information is lost since the
second file saved to the flash drive includes all the records that were in the first file.
However, if a copy operation is performed, and the SDM-E2’s memory is cleared,
then additional bump tests or calibrations are performed, and another copy operation
is performed with the same flash drive all on the same day, this will result in the
information in the file from the first copy operation being lost. This is because the file
saved to the flash drive in the second copy operation only includes records since the
memory was cleared and when it overwrites the file from the first copy operation, all
the information in the first file is lost.
CAUTION: If copying an SDM-E2’s memory to a flash drive multiple times during
the same day and the SDM-E2’s memory is cleared, transfer the
calibration/bump test record files from the flash drive to a computer
hard drive or some other memory device before performing another
copy operation to avoid loss of data.
