Setting section
Setting methodCan edited with using membrane switch. Setting can be performed by external 
devices as well via USB, RS-232C and RS-485 interface and so on.
Setting value memoryParameter, calibration and part of other settings are stored on NOV.RAM 
(non-volatile memory), and all other settings are stored on F.RAM (another 
non-volatile memory).
Setting value protectionOverwrite protection by "LOCK" switch
