Add one of 24 predefined Operator Messages (see Section 4.4.5) or one User Defined
Message to the alarm event log. If User Defined is selected, a data entry keyboard appears
to enable the message to be entered – see Fig. 4.5. The selected or user defined message
is displayed briefly in a dialog box. If Operator Message annotation is selected (see Chart
Annotation below) the message is also added to the chart.
Note. When the instrument is in Historical Review mode, Operator Messages generated
are added at the current time, not the time indicated by the cursor.
If an alarm or operator message is obscuring part of a chart trace, use the Chart
Annotation option to hide or display alarms and messages on the screen.
Select the annotation required.
The possible combinations are: No annotation (Alarms and Operator Messages both
disabled); Alarm annotation only or Alarms and Operator Message annotation. Operator
Message Annotation cannot be enabled unless Alarm Annotation is also enabled.
Notes.
• If more than 15 icons are present on the screen, chart annotation is disabled
automatically.
• When chart annotation is disabled, new operator messages and alarms are still added
to the Alarm event log – see Section 2.7
Use the Screen interval to change the amount of data displayed on the screen. A longer
screen interval displays more data, a shorter screen interval displays data over a shorter
time period, but in more detail. In both cases, the full trace is preserved by plotting the
maxiumum and minimum samples for each display point.
Longer interval =
better overview
When Basic configuration is selected, the maximum screen interval is determined by the
sample rate. These restrictions are not enforced when Advanced configuration is selected,
but are recommended to avoid an excessive delay before the new screen is displayed.

Notes.
•
A 'Please Wait' dialog box appears while the instrument retrieves data from storage.
•
Selecting a different screen interval does not affect the rate at which data is sampled.
•
When in historical review mode, changing the scan interval may cause the time at the
cursor position to change slightly.
