TDR100

Example 3, Measure and Record; Volumetric Water Content and Analog

Measurements

Eight CS605 or CS610 probes are connected to Channel #1 through #8 of a

Level #1 SDMX50 multiplexer. A cable length value of 10 meters was

determined using PCTDR. The La/L value is converted to volumetric water

content using the Topp calibration. The program is executed every two

minutes. The array id, time, volumetric water content and analog

measurements are output to Final Storage every two minutes.

;Measure the 8 CS610 probes connected to the level 1 SDMX50, return La/L:

;When creating the program with Edlog, the user must manually allocate the 8 input

;locations (i.e.: "LaL_1" through LaL_8"). For Edlog's help on how to do this,

;right mouse click the La/L parameter, select help, then click on

;"manually inserting input locations in Edlog".

;The following loop applies Topp's calibration to the 8 La/L values.

;One La/L value is converted with each pass through the loop. The indexed

;input locations (those with "--" to the right) are incremented each

;pass through the loop. (Index an input location in Edlog by pressing "F4"

;while the input location is highlighted).
