2.5.2 Numeric Format
The Model DF868 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:
I
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.
