2.5.2 Numeric Format
The Model GS868 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 GS868 automatically displays the chosen log file records in the specified
graphical format.
