YSI 600DW-B Sonde - Manual (Page 164)

650 MDS Section 3
Once these conditions are met, follow the instructions in Section 3.5.3 above for logging of sonde sensor
readings to 650 memory. The barometer readings will automatically be added to the file at the sample interval
selected for the sonde readings.
Barometer readings stored in 650 memory will remain as part of the sensor data file that can be viewed
from the 650 display and/or uploaded with the data file for analysis in EcoWatch for Windows. The
barometric pressure readings are processed as a normal parameter by EcoWatch, with the user having the
ability to change units from the EcoWatch menus. For example, data stored in 650 memory in units of mm
Hg units can easily be converted to readings in mBar after upload.
