Follow the prompts on this screen to prepare your 600XLM, 6600, 6920 or 600 OMS (battery version)
sonde for unattended deployment as described below:
To verify and/or correct the time and date enter 4-Status or 5-System menu from the Main menu.
You may enter the correct date and time from either of these submenus.
‰ Select 1-Interval and enter the desired time between samples (e.g. 15 minutes in the screen
above). Use the 24-hour clock format to enter interval.
‰ Select 2-Start Date and 3-Start Time to set the time that data will begin to log to sonde
memory. 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. If you should desire to start the instrument at the site at 6:00
PM as noted in the above example, 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.
