list lrec
list srec
list stream
list sp
These commands report the list of current selections for lrec logging
data, srec logging data, streaming data output, or the scratch pad (sp)
list.
The scratch pad is a temporary memory area which is used to set up lists
of selections for lrec, srec, or streaming data items. The user can copy
any of these lists to the scratch pad, modify individual elements in the
list, then save the scratch pad back to the original list. Refer to the “sp
field” command for information on how to edit the scratch pad.
The following example shows the list for streaming data output.
Send: list stream
Receive: list stream

lrec aa:bb oo-pp-qq yy
srec
aa:bb oo-pp-qq yy
rec = The starting record index number (1=most recent)
num = The number of records to return (1 to 10)
x = | 0 | 1 | : Reply termination format (see “set format format”
command)
y = | 0 | 1 | 2 | : Output format (see “set lrec/srec format format”
command)
aa = hours (01 to 23)
bb = minutes (01 to 59)
oo = month (01 to 12)
pp = day (01 to 31)
qq = year
These commands output lrec or srec logged data. 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, assume there are 740 lrecs 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.
