Linking Events
You also have the option of linking events.
Without linking, each of the four events acts
alone and independently as a trigger for a
measurement recording.
In the line Joint events (options shown to
the right) a drop-down list opens containing
the linked event options. In the example, the
linking of Events 1 and 2 (shown on the left
by a circuit diagram symbol) means that re-
cording is EITHER triggered by the simulta-
neous occurrence of events 1 and 2 (the
measured value in channel A drops to 5.00
bar, with the measured value in channel B
leaving the window of 4.00 to 6.00 bar at the
same time)
OR a voltage signal (falling signal edge) is
detected at trigger input J,
OR a key or button is actuated.
Other event linking options are shown in the
drop-down list. It should be borne in mind
that events are always listed in descending
order, otherwise you have to re-sort the
events.
In the 1 and 2 and 3 and 4 option, all events
have to occur simultaneously in order for a
recording to be triggered. By contrast the last
option
– 1 and 2 & 3 and 4 –
provides three variants:
A triggered recording is initiated when
a) 1 and 2 coincide or
b) 3 and 4 coincide or
c) all, i.e. 1 and 2 and 3 and 4, occur simul-
taneously.
