Panametrics DigitalFlow GF868 - 2.5 Log and Signal Data Display

2.5 The LOG submenu
The LOG submenu permits the display of the data in a log file
either graphically or numerically. Although the model GF868
can display all of the data in a log file, screen size limitations
prevent the simultaneous display of the complete log
file. Therefore, the function keys must be used to view the
remaining data. Follow the instructions in this section to
display a log file in the desired format.
2.5.1 Entering the LOG submenu
Press the appropriate side of the [SCREEN] key to activate
the desired pane of the display screen, and complete the
following steps:
1. To access the display menu, press the [DISP] key.
2. Press [F4] = LOG.
3. Use the [], [] and [F1]-[F4] keys to select the desired
log file to display. At the NAME prompt, the option bar will
show the names of all log files that are currently stored
in memory. If there are no log files currently stored in
memory, the following prompt will appear instead:

All Logs Cleared!
hit key
There are no log files
currently stored in memory.
Either all of the log files
have been cleared or no
log files have yet been
created. Press any key to
return to measurement
mode.
If the all logs cleared! prompt appears, at least one log file
must be created and stored in memory before the display
log function can be accessed. See chapter 3, logging data,
for instructions on creating a log file. After at least one log
file is stored in memory and selected at the NAME prompt of
the LOG submenu, proceed to the next step.
4. At the format prompt, press [F1] to display the selected
log in numeric format or press [F2] to display the selected
log in graphical format.
5. Do one of the following:
• If you pressed [F1], go to 2.5.2 Numeric format
for details.
• If you pressed [F2], go to 2.5.3 Graphical format
for details.
2.5.2 Numeric format
The model GF868 can log up to three parameters
simultaneously. Each set of data values is called a record,
and up to 120 consecutive records can be stored in a page.
A log file can consist of up to 120 pages. The numeric log
display, which shows one record at a time, includes the
following components:
• page number
• record number
• time and date of creation
• measurement value set
• error messages (if any)
Upon choosing NUM at the FORMAT prompt, the first record
of the selected log file is displayed in a screen similar to the
following:
PAGE# 1REC# 80

09 MAR 98
11.66 Ft/s
1.32 KACF/MI
6.91 KACF
E5: Amplitude
<CURS CURS> <PAGE PAGE>
Use the [], [] and
[F1]-[F4] keys to view
additional records or to
exit the log display. The
options are listed in
table 11.
In the numeric display screen, the locator bar (except for
the inverse video pointer at the far right) is replaced by a
standard video display of the page number and record
number. The first line of the prompt area shows the time and
date that the record was created, and the next three lines
list the values for the three logged parameters.
Finally, any error condition that existed at the time the record
was taken is indicated by an error code in the bottom line of
the prompt area.
