Calibration and Bump Test Records • 94
"Bump Test and Calibration Record Files" below for a discussion of these files
and how to use them.
Clearing the SDM-2012’s Memory
Make sure that you save the bump test and calibration records in the SDM-2012’s
memory to a flash drive before clearing its memory. The docking station’s memory
can be cleared by simultaneously pressing and holding the CAL
S
and COPY
buttons for five seconds. After the SDM-2012’s memory has been cleared, the COPY
LED will turn off indicating there are no records to be copied.
Bump Test and Calibration Record Files
Each time a copy function is performed, a file is saved to the flash drive in the DAT
folder. The file name will begin with “SDM-2012” and the remainder of the file name
will depend on the serial number of the SDM-2012 used and the date of the most
recent bump test or calibration performed on the SDM-2012. So it is possible to have
multiple files in the DAT folder from the SDM-2012.
The files that an SDM-2012 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 97 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-2012 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 bump tests or calibrations are performed, 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 bump tests or calibrations are performed, a copy operation is performed,
and the SDM-2012’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 performing bump tests or calibrations and copying an SDM-2012’s
memory to a flash drive multiple times during the same day and the
SDM-2012’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.
