PrEtr – Pre-Trigger
The pre-trigger function is activated when PrEtr = on:
The following conditions must be fulfilled in order to store
measurement values to memory:
• The memory mode must be active.
• The start time which has been defined with the timer
(t.triG and d.triG) must agree with current actual time.
Storage is carried out independent of any other trigger
conditions.
The pre-trigger function is deactivated when PrEtr = oFF:
The following conditions must be fulfilled in order to store
measurement values to memory:
• The memory mode must be active.
• Trigger conditions for the functions out, in, St-ou
and St-in must be fulfilled.
Storage to memory is carried out independent of the timer.
Note!
☞
The pre-trigger can only be activated, if trig=in or
trig=out has been selected.
We recommend the entry of a defined memory
duration prior to activation of the pre-trigger, (see
"durA – Memory Duration", page 30).
rEtrG – Re-Trigger
After a trigger signal and storage to memory have occurred
– memory duration durA has expired – the trigger is reset.
The re-trigger function remains disabled as long as the
pre-trigger function is active.
See the trigger menu flow chart on page 36 regarding
activation and deactivation of these trigger conditions.
Note!
☞
We recommend the entry of a defined memory
duration prior to activation of the re-trigger (see
"durA – Memory Duration", page 30).
t.triG, d.trig – Timer
If this function has been activated, and if the memory
mode is on, measurement values are only stored as of the
specific point in time, after which current date and time
agree with the values selected for t.triG (tiME triG) and
d.trig (dAtE triG).
See the trigger menu flow chart on page 36 regarding acti-
vation and deactivation of the timer.
Note!
☞
Current date and time should be checked and cor-
rected if necessary, before the time trigger is acti-
vated, and before trigger date and time are
selected.
