Indication of output states:
OUT 1 (Alarm 1); OUT 2 (Alarm 2);
OUT 3 (Alarm 3) OUT 4 (Alarm 4)
"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
