Follow the prompts on this screen to prepare your sonde for unattended deployment as described below:
 Verify that the current time and date are correct to ensure that your unattended sampling study begins
and ends when you desire. To verify correct the time and date, return to the Main menu and enter 4-
Status or 5-System. You may enter the correct date and time from either of these submenus.
 Select 1-Interval and enter the desired time between samples
 Select 2-Start Date and 3-Start Time to set the time that data will begin to log to sonde memory. .
Use the 24-hour clock format to enter the time. If you do not make any change to these entries, then
the study will automatically begin at the next integral time interval once you have pressed C-Start
logging.
Example: If the current time is 17:20:00 and your sample interval is 15 minutes, logging will
automatically begin at 17:30:00.
It is better to start the study prior to taking the unit to the field so that you can confirm that readings are
being saved to memory and carry out initial quality assurance. However, if your study demands that you
start the instrument at the site at 6:00 PM, change the Start Time to 18:00:00.
 Select 4-Duration and set the length of the study in days. The default value is 365 days (which is
longer than most deployments). In most cases, you will either want to stop the unattended study
manually or allow the batteries to be expended. It is wise to set the duration to a value longer than the
anticipated deployment. If you cannot retrieve the sonde at the expected time due to factors beyond
your control such as weather or illness, data will continue to be acquired as long as battery power is
present.
 Select 5-File and enter a name of no more than 8 characters that will be used by your external
computer to identify the study. Be sure to use ONLY alpha/numeric characters.
 Select 6-Site and enter a site name of no more than 31 characters. This filename will appear in your
sonde file directory, but will not be used to identify the file after transfer to your computer.
 Check 7-Battery to make certain that the voltage is suitable for the length of the study that you are
about to begin. No change can be made to this item via the software. Note that no battery entry will
appear for the 600R, 600QS, 600XL, and 6820V2-1 sondes.
