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.
