Download Collected Data

After you configure the DataStation, it automatically collects data
from those Em50R loggers that are within range and share the same
Channel and Subchannel. After collecting data, you can retrieve it
for permanent storage and analysis. DataTrac 3 is best suited for
this application.
To download and view data from the DataStation, start DataTrac.
In the DataTrac 3 menu, pick the DataStation you want to connect
to and click "connect." Click the "Download New Data" button.
The Downloading DataStation Data screen appears and provides a
progress bar displaying the download progress.

Data Processing

DataTrac 3 automatically sorts the data collected by the DataStation
and associates the data with the correct logger. However, unless you
used DataTrac 3 to also configure your Em50R loggers, DataTrac 3
does not know your logger name and which sensors are plugged into
each port. To add this information to your data set, click on the
appropriate Em50R in the logger tree and select "Configure."
If DataTrac 3 is not an option, you can use ECH20 Utility to re-
trieve data from your DataStation. ECH20 Utility gives you several
choices for the file type when downloading data from a DataStation.
Section 4 has more information on using ECH20 Utility for down-
loading data.
If you choose processed or raw data file formats, ECH20 Utility walks
you through processing the data for each active logger. The ECH2O
Utility prompts you for the logger type and sensor types for each
logger. This information is necessary for ECH20 Utility to process
the data correctly.
