3.6 EVENT TRIGGERING
The recorder has the ability to be triggered by certain events that are generated internally
or, optionally, externally, which will enable it to automatically change sampling speed or
begin or end a recording session. The trigger can be any alarm or the external input. The
user can thus set the unit to record at a slow sample speed until some alarm condition is
triggered and then change to a higher sample rate to record the transient. Another example
is the use of the external event trigger to start and stop recording allowing the selective
recording of specific events.
The event triggering is setup in the Advanced Setup Menu option. The control of recording,
stopping and starting is set in the REC. TRIG. (Record Trigger) menu option (Section 4.9),
while the changing of sample speed is controlled via the SAMPLE TRIGger menu option
where a second set of sample speeds will be presented for the triggered speed change
(Section 4.8). This rate may be slower or faster than the regular rate depending on
application.
The external event may be used in the same manner as the internal alarms for triggering a
change of speed or record status. The external event trigger characteristics are set in the
ADV. SETUP - EXT. INPUT menu option.
If the recorder is triggered but not recording, the red LED will blink at a 1 second interval.
3.7 STATUS LINE INDICATORS
The bottom line of the graphics LCD display is used to indicate the status of the display and
of the recorder itself. These status icons consist of reverse video characters or letters that
appear according to operations performed and are intended to prevent data on the display
from being misinterpreted and to indicate the status of the alarms.

number of them may be present depending on how the alarms have been set up. If an
alarm is enabled a solid block will be present. If the alarm has exceeded the setpoint (i.e. is
in an alarm condition) its symbol will be blinking.

this symbol will blink.
