The figure above shows an example for a fully automated sequencer with three sets of
parameters (A,B and C). Here the repeat counter (n) is set for (A=5), (B=3), (C=2) and the
loop counter (m) has a value of 2.
When the sequencer is started, with or without an external event, the camera will record
the pictures using the sets of parameters A, B and C (which constitutes a sequence).
After that, the sequence is started once again, followed by a stop of the sequencer - in this
case the parameters are maintained.

The figure above shows an example for a half-automated sequencer with three sets of
parameters (A,B and C) from the previous example. The frame counter (z) is set to 2. This
means the camera records two pictures after an incoming
trigger signal.

Trigger Delay:
The trigger delay is a
flexible user-defined delay
between the given trigger
impulse and the image cap-
ture. The delay time can
be set between 0.0 μsec
and 2.0 sec with a stepsize
of 1 μsec. In the case of
multiple triggers during the
delay the triggers will be
stored and delayed, too.
The buffer is able to store
up to 512 trigger
signals during the delay.
