& Data Type

WindowLength
Constant or
Variable
The WindowLength parameter specifies the length, in meters, of the
waveform to collect or analyze. The waveform begins at the CableLength
and ends at the CableLength + WindowLength. This is an apparent length
because the value set for Vp may not be the actual propagation velocity. For
water content measurements, the WindowLength must be large enough to
contain the entire probe reflection for probes with 20 to 30 cm rods. A Vp =
1 and Window length = 5 is recommended.
ProbeLength
Constant or
Variable
The ProbeLength parameter specifies the length, in meters, of the probe rods
that are exposed to the medium being measured. The value of this
parameter only has an affect when Option 0, La/L, is used for the
measurement.
ProbeOffset
Constant or
Variable
The ProbeOffset is an apparent length value used to correct for the portion
of the probe rods that may be encapsulated in epoxy and not surrounded by
soil or other medium being measured. This value is supplied by Campbell
Scientific for the probes we manufacture. The value of this parameter only
has an affect when Option 0, La/L, is used for the measurement.
Mult, Offset
The Mult and Offset parameters are each a constant, variable, array, or
expression by which to scale the results of the measurement.
