Part No.: 669855
The next setting parameter for recording a
triggered measurement curve is
Pre/post
trigger
. After starting a triggered measure-
ment curve the HMG begins to record the
measured values for the recording time set
(e.g. 30 seconds). If the trigger event does
not occur during this time, the oldest meas-
ured values are replaced with new measured
values in the measured value memory. This
means that you always have the set record-
ing time as the "past" in the measured value
memory.
The
Pre/post trigger
option enables you to
specify how much of this "past" is to remain
in memory when the event occurs and how
much "future" you would like to record after
the event.
A
Pre/post trigger
setting of 50 / 50%
means that for a recording time of 30 s the
"oldest 15 s" are discarded, 15 s remain be-
fore the occurrence of the event, and record-
ing is done for another 15 s after the trigger
event occurs.
With
Automatic mode
you define whether
you wish to make just one recording (
De-
activated
) or whether, after recording one
measurement curve, another curve is to be
recorded using the same settings (
Activat-
ed
). For a
Simple triggered measurement
,
select the
Deactivated
automatic measure-
ment option.
Zoomed area
With the "zoomed area", an additional dis-
play area can be created during the record-
ing in the graphic mode.
In other words, with the
Magnifier
setting,
the x-axis is scaled to the time span preset in
this menu point (5 seconds / 10 seconds).
(The setting options for the zoomed area are
dependent on the preset sampling rate and
the specified recording time.)
