Instruction Manual
Each marker may also start an action. The following
actions can be assigned to a marker.
Recording: The marker will start an audio recording.
Setting of the audio recording such as pre-trigger, # of
bits and sampling is set in the
Audio Recording
menu
found in the Measurement menu.
Picture: A picture is taken when the marker is activated.
This feature is only available on external cameras.
See
“Camera” on page 62
describing the camera
functions.
Digital Output: A digital output line will be set when the
marker is activated. A digital output must be assigned
to the marker. This is configured in the
Digital I/O menu
found in the
Instrument Setup
menu.
Reference tone: This will add tone signal to the time
profile in the similar way as an audio recording. Mainly
used for adding a “calibrated” sound level to the start
of a measurement. The signal type, level and excitation
time is set in the
Reference Tone Setup
found in the
Instrument Setup
Menu.
System specified markers
In addition to the user defined markers described
above, other markers may be inserted by the instrument
itself.
Pause marker:
As discussed in
“Pausing and resuming
a measurement” on page 66 , a yellow toggle marker
including a blue shaded field indicates the duration of
the pause. The values obtained in the pause area are
removed from the global measurement, but remain in
the profile. The single marker “P” is added to the periods
to denote that these periods contain data acquired in
pause mode.
Continue: A red single marker labelled “C” for continues
is inserted in the time profile if you terminate an ongoing
measurement prematurely by pressing the
STOP
key
and later resume the measurement by pressing . The
“C” marker will be added to the period within which the
key was pressed.
Recording: An orange recording marker is added to
the profile during recording of the signal.
Signal Overload:
A red marker is added to the profile if
the input circuit is overloaded. I.E. the measured signal
is higher than the measurement range.
DSP Work Overload: A black marker is added to the
profile if some of the specified tasks have been omitted
due to work overload for the signal processor.
Battery Marker: A marker is inserted when the
instrument is powered from the internal batteries.
Event Marker: An event marker is inserted when the
event trigger condition is fulfilled.
The Property button at the top of the menu gives you
the option to turn on/off the battery marker and/or the
Event marker. Please note that the battery and event
markers will be available in NorReview regardless of
the setting in this menu.
