The limit output may work in Alarm mode too. This mode is
switched ON by the

parameter. According to the
default factory setting it is switched off (

). When the
Alarm mode is ON (

), the limit output switches on when
it has to switch on according to the measured and
displayed physical value, but it will not switch off even if the
value changes so that it should cause it to switch off. The
output can be switched off by pressing the
ENTER button
only (acknowledgement).
Alarm Mode
Of course, if the condition that causes the output to switch
on persists, the limit output will switch on again when the
ENTER button is released.
After switching on the instrument
After switching on the instrument the limit outputs are
disabled as long as it performs at least three
measurements necessary for a complete averaging. This
takes a few seconds maximum. In this way can be avoid
false signalling due to transients that may appear in the
measuring loop.
