These parameters can perform double role. Firstly, when you wish to collect data right after or before the event
that caused logger trigger. Secondly, when it is necessary to have continuous logging, but the source is
oscillating near the threshold level. The extension of the registration window allows you to avoid the effect of
pulsation.
4.4.5 Setting markers
– Marker Setup
Marker is used to mark (or highlight) special events during the measurement such as "airplane flight" and is
nothing but an indication of the beginning and end of the block of logger results in which the event occurred. In
case of point markers, there is no start and end of the marker, but only one record in the logger file. Markers are
activated in the result presentation views by pressing the arrow keys.
The Marker Setup screen allows you to
assign a specific name for each marker,
select its type (normal or
Point ) and define
markers for triggering wave recording ( Trig
column).
<ENT>
Name edition is performed in the text editor
screen after pressing the
► key together
with <Alt> .
<Alt>+
►
The Trig column becomes active only when
Trigger on Marker ( path: <Menu> /
Measurement / Logging / Wave Recording )
is enabled.
Switching on Trig for some markers means,
that wave recording will be triggered by
activating one of these markers.
