Example 4, Measure and Record; Analog Measurements and Volumetric
Water Content
In this example analog measurements are made every 5 minutes and TDR100
measurements are made every 60 minutes. Twenty-nine CS605 or CS610
probes are connected to 4 SDMX50 multiplexers (Figure 10-1). The cable
length values were determined using PCTDR. The La/L value is converted to
volumetric water content using the linear calibration function of Ledieu, etal.
(1986). The program is executed every 5 minutes. The array id, time, average
of the analog measurements and the volumetric water content measurement are
output to Final Storage once an hour.
