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.
