“Raise” and “Lower” keys:
These keys are used for any operation that requires a
numerical parameter to be raised or lowered. ••The
speed of change is proportional to the time the key is
pressed. •• The operation is not cyclic: once the
maximum (minimum) limit is reached, there will be no
further increase (decrease) of the value, even if the
key remains pressed.
The keys can be configured to perform reset, hold,
display of the peak value, etc. as determined by the
‘t.U.’ and ‘t.d.’ parameters on the ‘In’ menu.
