If you started sampling without entering a filename, the default name NONAME1 will be assigned to your
file. Whenever you press 1-LOG last sample or 2-LOG ON/OFF from the menu, NONAME1 will be
opened during sampling. If this happens, and you want to restart the file with a different name, press
5-Close file and rename the file.
Select 4-Site to assign a site name with a maximum of 31 characters. This allows you to enter the name of
the site where you are sampling.
When you select 5-Open File, a file is opened and the number 5 changes to Close File. When you are
finished logging data to the file, press 5-Close File and number 5 changes back to Open File.
Now select 1-Start sampling to start discrete sampling.
After the initial sampling time interval has passed, (e.g. 4 seconds in the example 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 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 to exit discrete sampling.
