2.5.3 Graphical Format (cont.)
In the typical graphical display shown, the first logged parameter (VEL) is shown to the left of the y-axis and there is a
message line below the graph that initially indicates the starting date and time of the current page. Notice that most of
the locator bar has been replaced by a status line in standard video that shows the value, units and time of the record at
the current cursor location. However, there is still an inverse video pointer at the far right of this line to indicate that
additional option bar choices are available.
Note: The date in the message line includes only the day and the month (not the year), and the times in the status line
and the message line include only the hours and minutes (not the seconds).
Because the times displayed in the
LOG graph are in whole minutes only, movement of the cursor may not result in a
visible change in the posted times. For example, if a TIME INCREMENT of 30 seconds has been programmed, two presses
of either cursor movement key will be required to change the displayed time by one minute.
2.6 Displaying the Transducer Signal
The SIGNL submenu permits the direct graphical display of several transducer signals. Specifically, the signals listed in
Table 9 may be viewed in this format.
Note: The Measure type signals (Mup and Mdown) are only available if the
S/M burst technique was selected in the
ACTIV menu.
Refer to Figure 14 on page 90 and complete the following steps to display the transducer signals. Press the appropriate
side of the
[SCREEN] key to activate the desired pane of the display screen, then proceed as follows:
Note: For this discussion, it is assumed that the left pane of the display screen is active. If the right pane is active, it
is only necessary to replace the
[F1]-[F4] keys designations by the [F5]-[F8] keys.
1. To access the Display Menu, press the
[DISP] key.
2. Press [ and [F1] = SIGNL.
3. Press [F1] to display the Skan type signals or press [F2] to display the Measure type signals.
