Basic principles 

To function correctly, the data logging system must be set correctly and this setting must be transferred to 
the multimeter (on the RS232 link) or to the network of multimeters connected in the RS485 network. The 
data saved in the flash memory of each multimeter can be recalled and saved in an MS-Access format 
project file and converted into other formats (ASCII or Excel). 
The graphs of each individual measurement can be displayed and printed. 

 

Main window 

The main window of the program contains all the menus and the toolbars for access to the various functions. 
As they may modify the configuration of the software, some of these functions are protected by a password 
and are therefore disabled when the program is started. The main window is illustrated in the figure below 
showing the most frequently used controls.
