Use the keys +/MAX and -/MIN to change the value of actual parameter and the key
SCROLL to access the next parameters.
Pressing the key RESET/PHASE (for 5 seconds) will force the default value of the
parameter.
To exit the setup mode, wait for 10 seconds without pressing any key: finally the device
will come back to measure mode.
