Displaying Data 2-5

March 2008

Using the GRAPH Format While viewing data in the GRAPH format, the function keys are

programmed to permit a variety of actions. These options are

described in detail below.

At any given time, 120 data points will be shown on the

GRAPH

screen. The cursor, which is displayed as a vertical line that extends

the full height of the graph window, can be used to select any one of

these data points.

The typical screen shown above is for a Velocity vs. Time graph with

only the positive y-axis displayed. The measurement 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 graphed

data. Notice that most of the locator bar has been replaced by a status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

measurement 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

GRAPH format 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.

1.23 Ft/s 10:16 ‰

Use the [←], [→] and [F1]-[F4]

keys to select the desired option.

See Table 2-2 on the next page

for a listing of the available

choices.
