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:
f 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: Cl2 Chg, pH mV, NH4
+
mV, NO3
-
mV, Cl
-
mV, and
Fluorescence %FS. 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 as items 9 and A. 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 entries. 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.
