Pressing starts the recording of the data in the * .csv file on the memory card or in case of activated
data streaming the transmission of the data to the connected computer.
Recording is ended in case of pressing or if it exceeds a pre-set limit value (see 3.1.2).
When the pre-set time is over, the recording will stop automatically. The file is closed and a new one
opens, or the transmission to the computer is stopped, when data streaming is enabled.
The file name for the stored on the SD memory card curves is Curvexyz.csv, where xyz stands for a serial
number beginning with 001, stands and is an Excel compatible file with the extension * .csv.

Saving is over when you choose the menu item “no saving” (see chapter ) or when the memory on
the SD card is completely full. The measurement data transfer through the data streaming remains active.
6.4 Data transfer in mass storage mode
Data transfer is carried out via the USB interface. The factory setting of the device makes it possible to
use it as a mass storage. It means that after the first connection to the computer a mass storage driver is
installed automatically, similar to the USB stick. Then the saved measurement data can be copied via
Windows-Explorer. Alternatively, the files can be opened directly via Excel and processed further.
In chapter it is described how the transfer mode can be changed.

When the
Data Streaming mode is enabled (see chapter ), the measurement data can be sent to a
computer continuously.
Pressing activates the transmission of data to the connected computer.
The data transmission is terminated when is pressed or when a pre-set limit value is exceeded (see
chapter ).
