Notes.
1. Current Values
The Current Value, shown on the digital indicators at the top of the screen, is the latest instantaneous value and its update
rate is not affected by the recording sample rate.
If the current value in the digital indicator is displayed in red, recording has been stopped for that channel – see Section 4.5.1,
Setting the Recording Parameters.
Traces are shown only when that particular channel is being recorded. When channels are set to stop, the trace continues
to be shown for up to one sample period.
2. Alarm Status
• Flashing Red – Alarm Active and Unacknowledged
• Continuous Red – Alarm Active and Acknowledged
3. Alarm Event and Operator Message Annotations
Alarm Event and Operator Message annotations are not shown on the chart unless enabled –
see 'Chart Annotation' on Page 8 and Section 4.5.2.
If Alarm event annotation is enabled and an alarm becomes active, a red alarm icon surrounded by a channel-colored box is
displayed at the point at which the alarm occured, together with the alarm time and tag.

• If the second alarm on a channel becomes active its icon is added behind the first.
• If more than one operator messages is active (max. six) a second icon is added behind the first.
• New alarm icons appear to the left of earlier icons.
• The time and tag of the oldest alarm (right-most icon) only is displayed.
