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 and dynamic 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 dual range, the long records and short records
contain the high and low NO and NO
low NO and low NOx values are set to 0 and the high NO and high NO
are used. In NO or NO
concentrations are set to 0. Concentrations are stored in either ppb or
3
μg/m
.
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.
