Chapter 2. Displaying Data
2.5.2 Numeric Format
The Model GC868 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:
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.
2.5.3 Graphical Format
After choosing PLOT at the FORMAT prompt, the programming sequence continues
as follows:
6. Enter a maximum value for the
Y-axis
(vertical) scale that is larger than the
maximum expected reading. Press [ENT] .
7. At the
Y Range
prompt, press [F1] to graph only positive Y values or press [F2] to
graph both positive and negative Y values.
After the Y RANGE is entered, the Model GC868 automatically displays the chosen
log file records in the specified graphical format.
