7.7 LOGGING MODE (YSI 610 DM ONLY)
The YSI 610-DM can log sample data to its internal memory from any YSI sonde. This is
separate from the sonde’s ability to log data into its own memory. Logging produces a
file in the standard file format, capable of being uploaded to a PC and processed by
EcoWatch for Windows. See Section 4, Logging for a detailed explanation.
Select Logging from the YSI 610-DM Main menu. Then select Setup Header. This menu
allows you to specify control and timing information for the deployment.
File: The YSI 610 file name to log data into.
Site: The Site name to embed in the file
StDate: Date to start logging ( use “now” if you wish)
StTime: Time to start logging ( use “now” if you wish)
Duration: Length of deployment (see Section7.5 for how to properly enter duration)
Interval: Recording interval (see Section7.5 for how to properly enter interval)
WarmupTime: Warm up time for the sondes DO sensor (seconds)
Press Esc to go back to the Logging menu, then select Setup Filter. The Setup Filter
menu allows you to automatically discard samples that do not meet your criteria.
Log All Points: Press Enter here to record all samples taken.
Wet Switch: Press Enter here to record only those samples taken when the
probe is wet. This only logs sample with a conductivity greater
than 180 uS/cm
Log Only When: Press Enter to activate the next three menu items.
Param: Press Enter to select a parameter for comparison ( selected from a
list)
Is: enter Above to record samples above the value, or below
Value: Enter a value in appropriate engineering units for
comparison.
The Start YSI 610 Logging menu begins the logging session that was specified in the
Setup Header and Setup Filter menus. If the file name specified already exists and was
created by Logging on the YSI 610, new data will be appended to the file. If the file
name does not exist, you will be asked if you want to create it, asked to enter a site name,
and asked if you want to enter the weather info. Pressing the Esc or Power keys
terminates logging. Logging stores all parameters to the data file even though only 12 fit
on the screen.
The Logging screen tells you how much space is available for additional logging, and
how much time this corresponds to in Logging mode.
If the sonde is equipped with a wiping turbidity probe, the probe will be cleaned
automatically before each sample but only if time permits. Cleaning takes up to 40
