lrec aa:bb oo-pp-qq yy
srec aa:bb oo-pp-qq yy
xxxx = the number of past records
yy = the number of records to return (1 to 10)
aa = hours (01 to 24)
bb = minutes (01 to 59)
oo = month (01 to 12)
pp = day (01 to 31)
qq = year
These commands output long or short records. The output format is
determined by the "set lrec format" and "set srec format" commands. The
logging time is determined by the "set lrec per" and "set srec per"
commands.
In the following example, there are 740 long records currently stored in
memory. When the command lrec 100 5 is sent, the instrument counts
back 100 records from the last record collected (record 740), and then
returns 5 records: 640, 641, 642, 643, and 644. For details on how to
decode the flag fields within these records, see the "flags" command.
