Computer Interface, Commands, and Data Collection Teledyne API Ultrafine Particle Monitor - Model 651
70 07506C DCN6727
Notes: Data records written to the flash drive are also echoed out
of the Ethernet interface on the Telnet socket. This allows
redundant e xternal data collection to be performed with
the Ethernet connection while data is being collected by
the flash drive.
You cannot change the SAMPLE TIME while data is being
logged - you must stop logging data first.
4. Press STOP to discontinue data logging at any time.
Note: Do not remove the Flash drive while logging data.
Do not restart data logging or go beyond 99 files. If you
do, data files may be overwritten.
5. Remove the Flash drive and connect it to a computer to
download the data.
Flash Memory Data Files The data is stored in files with the "dat" extension and a new file is
created either every day or every hour (depending upon the Logging
selection you have made). If you stop data collection at any time,
the current data file is saved even if it contains less than one
hour/day of data.
Every time a new run is started, a unique file is created. Each data
file has the following format:
Filename yymmddxx, where yy is the year (no leading zero), mm is the
month (1-12), dd is the day of the month, and xx is a sequence
number for the day (01-99). Example: 9110601.DAT where 9
is the Year, 11 is the month, 06 is the day, 01 is the file
number and .DAT is the extension.
LINE 1 “TSI CPC DATA VERSION 3”
LINE 2 Time stamp for the file: yy/mm/dd,hh:mm:ss where yy is the
year, mm is the month, dd is the day of the month, hh is the
hours, mm the minutes, and ss the seconds
LINE 3 Data average period (sample time intervals) in seconds.
