Select B-View Parameters to log to confirm that your sensor and report setups are configured
correctly as described in Sections 2.9.6 and 2.9.7. An example screen is shown below.
In some cases, the View params to log screen only identifies the raw parameters that are used in the
calculation of the items that you have selected in the Report setup.
Example: You have selected DO mg/L in the Report setup, but it does not appear under View
parameters to log because it is calculated from DO saturation %,Temperature, and Conductivity.
Likewise, although specific conductance is selected in the Report setup, it does not appear under
Parameters to log because it is calculated from Conductivity and Temperature. In all but a few
cases, the proper configuration of Parameters to log will be automatically set up as long as the
sensor is enabled.
There are several items that must be activated in the Report setup so they will be available from the file
after upload. These special parameters are: DO Chg, DOSat %Local, ODOsat %Local, pH mV, NH4
+
mV,
NO3
-
mV, Cl
-
mV, PAR1, PAR2, Chl RFU, BGA-PC RFU, and BGA-PE RFU. If you want to log any of
these parameters to your data file, be certain that they are active in the Report setup before you begin the
unattended study.
After making the above entries, the sonde software will automatically estimate the expected battery life,
and the time it will take for the sonde memory to be filled. This information is displayed on the screen for
your consideration. If the battery life or the free memory capacity will be exceeded sooner than the
duration, you may want to make some changes to the sonde set-up or the batteries themselves. For
example, you can free up memory in the sonde by uploading all existing files from the sonde memory to
your PC and then deleting them from the sonde (see 3-File from Main Menu). You may want to change the
batteries for longer battery life. You can lengthen the sampling interval to extend both battery life and
memory capacity.
The predicted battery life is an estimate only. The temperature of the site and the brand of batteries used
can affect battery life. It is recommended to recover the sonde earlier than the predicted battery life, and to
use new batteries for each deployment.
Once you press C-Start logging, the following screen will appear.
