5. Select “New” to start a new program to read the EC-
20, EC-10 and EC-5.
a. Select the datalogger you will be using to read the
sensors.
b. Select the measurement interval (a shorter mea-
surement interval, i.e. 1 sec., is sometimes desirable
when testing the sensor).
6. Click on Sensors (this should open a new page with
a file tree on it).
7. Under the “Sensors” file tree, double-click on
“Meteorological” and then select “Soil Moisture.”
8. ECHO Probe EC-10 and ECHO Probe EC-20
should appear on the tree along with other soil mois-
ture sensors.
a. If they don’t appear, check to make sure you have
pasted the files above into the correct location.
Calibration
Decagon’s ECH

O Utility Mobile, and
DataTrac automatically apply factory calibrations to the
sensors’ output data. However, this general calibration
may not be applicable for all sensors and all soil types.
While the factory calibrations for the EC-5 is appropri-
ate for almost all soil types, the standard calibrations for
the EC-20 and EC-10 sensors do not perform in soils
with high sand or salt content. Therefore, for added
accuracy we encourage our customers to perform soil-
specific calibrations.
The calibration equation that you will use depends on
where you will be using it. If you will be using it with
