Event Markers
Two buttons allow placement of event markers into a file, assisting the user during data
collection: Annotate and Time . During file recording, these events appear in the Event
panel.
• Pressing the Time button during recording places a time stamp in the data file. A
dialog box appears, showing the exact time that was written to the file. One use of
this function is to correlate data collection in a laboratory notebook or data collection
worksheet with the data in the file.
• Pressing the Annotate button during recording displays a dialog box wherein the
user may enter text notes. Clicking OK places the notes and a time stamp in the data
file. The time stamp represents the time that the OK button was clicked, not the
Annotate button.
Automatic Event Markers: In the absence of user events, such as Time or Annotate ,
there are only beginning and end of file events. Therefore, automatic event markers are
placed in data files to assist in the rewind and forward functions during playback. The
time intervals between automatic events can be adjusted.
To set the time interval:
1. Select
Timed Breaks form the File menu. The Timing dialog box displays:

This setting determines how often an automatic event marker is placed in the data
file.
2. Select the desired time interval between automatic event markers and click OK .
Event markers are used with the Forward and Reverse functions of file playback.
Shorter times let the user see more of the data during playback.
The software keeps a timer for the automatic event marker. If the user inserts an
event by using Time or Annotate , the timer is reset to avoid having automatic
events too close to user events.
