Supported file systems are FAT32. When a memory formatted in a different file system is insert-
ed, the device will display a window informing about detecting unformatted media carrier. From this
window, the user may directly enter the formatting screen.
The data on the memory stick are stored in the folder named " MPI-540_DATA".
5.2.3 Compatibility with Sonel Analysis software
Sonel Analysis is an application used to work with MPI-540 meter and power analyzers of PQM se-
ries. In combination with the above devices it enables to:
read data from the device,
real-time preview of the mains,
present data in the tabular form,
present data in the form of graphs,
analysing data for compliance with EN 50160 standard (reports), system commands and
other user-defined reference conditions,
updating firmware of analyzer to new and updating the application itself.
The software operates with Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 10.
Detailed manual for "Sonel Analysis" is available in a separate document (also downloadable from the
manufacturer's website www.sonel.pl).
5.2.4 PC connection and data transmission
Connection to a computer (PC mode), ensures transmission of data stored in the recorder memory –
it is possible to read data from all completed recordings.
When connected to a PC, the display shows message "PC Connection"
When connected to a PC, all buttons are locked except button, unless the recorder operates
with key lock mode (e.g. during recording ) – then all the buttons are locked. The icon whose
selection interrupts the connection with the PC is displayed on the screen on the bottom bar.
When within 10 seconds of connecting a PC to the device no data exchange occurs between the
device and the computer, the device exits data exchange mode and terminates the connection.
Sonel Analysis software also allows you to read data directly from a microSD card using an external
memory card reader. This method allows for the fastest reading of the recorded data. To use this
mode, remove the memory card from the meter and put it into the reader connected to a computer
(when removing the card, follow the rules described in sec. 5.2.1; it is safe to turn the meter off
earlier).
