4.2.2 Graphical Format
To print live data in graphical format, continue as follows:
8. Use the [, [ and
[F1]-[F4] keys to select the first parameter to be printed. See Table 15 for a list of the available
options.
Refer to Chapter 3, Diagnostics, of the Service Manual for a discussion of the many parameters accessible using the
DIAG option.
Note: The units assigned to the parameters in Table 15 are those selected in the User Program (
SYSTM submenu).
9. Enter the desired maximum value for the Y (vertical) axis and press
[ENT].
Note: Enter a Y AXIS MAX value that is larger than the largest expected measurement value.
10. At the Y Range prompt, press [F1] to show only the positive Y axis or press [F2] to display both the positive and
negative y axis.
11. Use the [, [ and [F1]-[F4] keys to select the desired Time Increment (the frequency at which measurements are
taken). The available options are: 5sec, 10sec, 30sec, 1min, 3min, 6min and 12min.
After the time increment is chosen, the Model GF868 returns to the standard data display screen and continues to take
measurements. The live data is printed at the specified time intervals, until a STOP command is issued (see the
instructions for the STOP submenu). A portion of a typical printout is shown in Figure 4.
