NIBP250 User’s Guide
3.6. Result File
After measurements are performed, the pressure and pulse signals (including the analysis results) can be saved
to NIBP internal memory, SD Card or USB Memory. If you insert any external memory NIBP250 uses it instead of
its internal storage.
Measurements are stored in the directory named as “NIBP” and assigns an unique name to each; i.e.,
“Rxxxxxx.nbp”. The “xxxxxxx” denotes the unique number for the measurement in the directory.
Measurement files are in ASCII format and can be imported by any text reader. The measurement file content is a
CSV file type with a semicolon separator and easily imported into common spread sheet applications. Table 3
shows a sample measurement file with a description of each line in the file.

3.7.External Memory Units
The NIBP250 has a USB 1.1 compatible flash memory port and SD card slot. External memory units must be
formatted to a FAT file system prior to use.
External memory units are automatically detected when connected, after which measurement data can be
transferred to a computer for further analysis or publishing. External memory units should not be inserted or
removed while the NIBP250 is actively loading or saving a measurement.
3.8. Firmware Update
The NIBP250 device firmware should be periodically updated. For firmware updates, check the NIBP product web
and download the “NIBP250Update.cab” file. Then copy the file to a FAT-formatted SD
Card or USB flash drive.
To update the firmware:
1. With the NIBP250 turned off, insert the SD card or flash drive containing the firmware update file into the
slot or USB port on the NIBP250 rear panel (see 2.2. Rear Panel).
2. Turn on the NIBP250. The unit automatically detects and updates the firmware, after which it will initiate
its regular startup cycle.
