Select 1 – Start sampling option to start discrete sampling. After the initial sampling time interval has
passed (4 seconds in the screen above), sequential lines of data will appear on the screen.

The following prompt will appear just below the screen header:
1-LOG last sample, 2-LOG ON/OFF, 3-Clean optics
• By entering 1–LOG last sample, A single line of data can be logged to sonde memory and the
following message will be displayed: Sample logged.
• By entering 2-LOG ON/OFF, a set of data can be logged to memory and the following message will
be displayed: LOG is ON, hit 2 to turn it OFF, 3-Clean optics. Press 2 again to terminate logging.
• By entering 3-Clean optics, if your unit has an optical (turbidity, chlorophyll or rhodamine WT)
probe, the wiper will clean the optical surface . The 3-Clean optics portion of the prompt will only
appear if an optical probe was installed and enabled.
Select
Esc or press 0 and return to the Discrete Sampling menu.
From the Discrete Sampling menu, select 2-Sample Interval to type a number that represents the number
of seconds between samples. The maximum sample interval is 32767 seconds (9+ hours). The factory
default sample interval is 4 seconds and works best for most discrete sampling applications. The shortest
possible sample interval for obtaining new free chlorine readings is 4 seconds. If a smaller interval is
selected, then the Cl2 readings remain constant for the number of samples necessary to fill 4 seconds.
NOTE: If your have used your sonde with a 650 MDS data logger, the Sample Interval automatically be
changed to 0.5 seconds.
