10.2 CR10X/CR23X Program Examples
Example 1, Measure and Record; Analog Measurements and Volumetric
Water Content
A CS605 or CS610 probe is connected directly to the TDR100. A cable length
of 6.25 meters was determined using PCTDR. The L
a
/L value is converted to
volumetric water content using the Ledieu , etal linear calibration function.
The program is executed once a minute. The array id, time, analog
measurements, and volumetric water content are output to Final Storage every
five minutes.
