General MSI functionality
Each MSI is a signal conditioner designed for a dedicated sensor type. By reading the TEDS chip, the measuring system
gets any information necessary to adjust the amplifier accordingly.
The user doesn't have to worry about it, he automatically gets the right measuring ranges with the right unit
displayed.
For traceability, important data, such as serial number or calibration date, are also read out and if necessary
additionally stored with the measurement data file.
