Micro-PWC OPERATOR’S MANUAL
60 Trend Displays
right corner of the Trend Graph. Clicking either of these A RROW buttons causes the Trend Readout arrow to
move along the top of the Trend Graph in the indicated direction. Each time the button is clicked, the point
of intersection between the Trend Readout arrow and the Trend Graph moves (in the direction selected) to
the next valid location of a collected value on the display.
6.1.4 Time at Arrow Button and Arrows
The Time at Arrow button displays the specific time and date toward which the Trend Readout arrow is
pointing. The format used is HH:MM:SS DD-MMM-YY. This allows the operator to be precise when inter-
preting the data on the Trend Display. (When the display is refreshed, the arrows shift along with the trace
so that the display of the value for the time selected by the operator is maintained.)
To move the Trend Readout arrow to point to a new time and date, click on the Time at Arrow button. A
pop-up window appears (
Figure 6-5 ) which contains an entry box and prompts for a new time and date.
(The Trend Readout arrow cannot be moved to a time prior to the beginning of a trend.)
The new time and date can be entered in the format shown (HH:MM:SS DD-MMM-YY). If a field is omitted
during entry, that field will default to the value used in the current Time at Arrow. (An exception to this rule
is the seconds (SS) field, which always defaults to 00 if no value is entered for the field.)
For example, if the current Time at Arrow is 10:17:32 30-JUN-05, then entering:
15-
will cause the Trend Readout arrow to move to 10:17:00 15-JUN-05.
It is also possible to move to a new time relative to that of the current Value at Arrows. To do so, prefix the
number to be shifted with a plus or minus to indicate in which direction the movement is to take place. For
example, to move the Trend Readout arrow to the point on the Trend Graph which is 10 minutes prior to
the current location, enter:
-:10
To move the Trend Readout arrow to the location five minutes after the current location, enter:
+:5
6.1.5 Trace On/Off Button
A set of three buttons is provided on theTrend Display for each of the eight possible traces. The first button
in each set is the Trace On/Off button, which displays the index number of the associated trace and con-
tains an ON/OFF indicator. The ON/OFF indicator is a red dot which is displayed when the trace is ON.
The indicator is not visible when the trace is OFF. Click the Trace On/Off button to cause the trace to tog-
gle between the visible (ON) and invisible (OFF) states.
Each trace can be configured to be ON (visible) or OFF (invisible) by default when the trend is initially dis-
played. (The Micro-PWC Configuration Guide provides details on the configuration procedure.)
