Data Recording and Transfer—SD Card
File Name Format for Data .txt Files
If an SD card is inserted into the SD card slot, files of the data measured at each measurement session
will be recorded in a file on the SD card in the .txt format (that is, in a simple text format). The filename
naming convention is comprised of the MonthDayHourMinute of the time when the file is actually
written to the SD card. For example, if the last BP determination of a session was done August 28 at
15:36 hours; the name of the text file containing all the readings on the SD card would be named:
08281536.txt (the naming convention for the Save Screen .jpg files is different; please refer to that
section for format). Since the year is not a part of the file name, if multiyear retention of the saved data
is important, the SD card should be replaced at least once a year to prevent the possibility that a
previous file would be over written by a new one saved at the exact date and time as an old one already
on the SD card from a previous year.
Measurement and Monitoring Data Recorded in Text on the SD Card
During use, the information generated in each BP determination will be recorded immediately after
each determination in a single line of the text file on the SD card. Care should be used when removing
the SD card so that it is not being done right at the end of the determination since this could corrupt the
file being updated, and potentially harm the SD card itself. (See note at the bottom of this section for
more information on corrupted files or SD cards).
The format of text output recorded on the SD card is as shown in the example below. (In the top line of
column labels, Dys stands for diastolic). Note that the HR obtained during the BP determination is based
on the pulsations in the limb with the BP cuff.
