6.3.24 RES
Reset. Reset the serial interface.
Deletes the input buffer. All queued error messages are
sent to the Host. The unit returns to the measurement

6.3.25 SAV
Save parameters to EEPROM.
The command SAV,0 resets all parameters to their
default values (factory settings). See Chapter 5.3.4
Default parameters (dEF), 27.
The command SAV,1 saves parameter values which
have been changed via the serial interface in the
EEPROM. These values will be preserved even when the
unit is switched off.
