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

sampling at 6:00 PM on July 31, 1996. The site is Clear Lake, near the spillway,
and you want to log all of the readings to a single file CLRLAKE3.
