8. Click Finish and save the program. Send the program to the data logger if the data logger
is connected to the computer.
9. If the sensor is connected to the data logger, check the output of the sensor in the data
display in
LoggerNet
,
RTDAQ
,
PC400
, or
PC200W
to make sure it is making reasonable
measurements.
5. Overview
The
SoilVUE
10
uses
time-domain
reflectometry
(TDR)
to
measure
soil
volumetric
water
content
(VWC)
and
electrical
conductivity
(EC).
The
waveguides
(measurement
rods)
are
embedded
in
threads
and
centred
on
the
measurement
depths
of
5,
10,
20,
30,
40,
and
50
cm
for
the
0.5
m
option
(
5))
and
60,
75,
and
100
cm
are
added
on
for
the
1
m
option.
The
threaded
design
maximizes
soil
contact
and
minimizes
preferential
flow—two
major
drawbacks
to
smooth-sided
soil
profiling
probes.
Campbell
Scientific’s
proprietary
implementation
of
TDR
produces
a
clean,
high
resolution
measurement
that
provides
accuracy
and
assurance
that
cannot
be
found
among
other
commercially
available
sensors.
