3.4.3 CIRCULAR TREND (Cont.)
TIMESTAMPS
Time and/or date are displayed at every major chart division. The following rules apply:
1. For chart durations of a week or more, only the date is displayed
2. For chart durations of less than a week, both time and date appear, with the following exception:
In ‘New Chart’ mode (unless the chart ‘bridges’ midnight), the date appears only at top centre of the
chart. All other chart divisions are identifi ed by time only.
OTHER NOTES
1. Adaptive recording results in two traces per trend, as in other trend display modes.
2. For successful circular trend display, ‘Circular Settings’ must be enabled for the relevant group
(sec-
tion 4.3.2
), and ‘Circular Trend’ must be enabled for the group, in Views confi guration (
section 4.3.4
).
If Circular Trend is enabled, but Circular Settings is disabled, then, although the circular chart will
appear, it is unlikely that it will contain any trends.
3. The circular chart speed is unaffected by A/B switching of Trend Speed/Interval (
section 4.3.2
).
4. Circular trends backfi ll only to the previous power up. Unless the parameter ‘Circular Extended
Backfi ll’ has been enabled for the group in Group confi guration
(section 4.3.2
), then circular trends
will backfi ll multiple power cycles.
