3.5.4 650 LOGGING – "CANS" AND "CAN'TS"
The use of the 650 to facilitate the storage of data from YSI 6-series sondes has been described in some
detail in the sections above. Unfortunately, the high levels of capability and flexibility of the 650 logging
function might also be viewed as complexity which, in turn, can confuse some users about how to employ
the 650 in their particular application. This section is designed to help with any confusion that exists by
listing what "can" be done with the 650 logging system and what "can't" be done.
3.5.4.1 SUMMARY OF 650 LOGGING CAPABILITIES
WITH A 650/YSI SONDE SYSTEM, THE USER CAN:
 Log sonde sensor data to either sonde memory (if your sonde is so equipped) or 650 memory.
 Log data as either a single point or as a continuous data stream.
 Log data in both single point form and continuous stream form to the same file in 650 or sonde
memory.
 Log continuous data stream data at long or short sample intervals to sonde memory, as long as the
study is started from the Run menu of the sonde.
Log continuous data stream data at long or short sample intervals up to 15 minutes to 650 memory

using the Sample interval selection in the Logging setup menu of the 650.
 Log data from the 650 internal barometer to the memory of the 650.
 Log data from a user-supplied GPS unit to the memory of the 650, as long as the GPS unit is set up in
NMEA format and has the proper cable.
 Log data with minimal keypad entry from the 650 display by using default file naming.
 Assign custom file and site names using the 650 keypad at the logging site.
 Set up custom site lists in the office or laboratory that are instantly available in the field to simply
file/site management.
 Set up Site Designations that are characterized by a File Name and a Site Name for simple logging of
data from a single site to a single file.
 Set up Site Designations that are characterized by a File Name, a Site Name, and a Site number which
correlates with the Site name. These lists allow the logging of data from more than one site to the
same file.
 Easily view data on the 650 display that has been stored to either sonde or 650 memory.
 Easily upload data that has been stored in either sonde or 650 memory to a PC for analysis using
EcoWatch for Windows software from YSI.
