CS616 and CS625 Water Content Reflectometers

Timeout: The Timeout parameter is the maximum time duration, in

milliseconds, that the datalogger will wait for the number of Cycles to be

measured for the average calculation. An overrange value will be stored if the

Timeout period is exceeded. A value of 1 is recommended if 10 is used for

cycles parameter.

Port: The Port parameter is the control port or analog channel that will be used

to switch power to the CS625 Water Content Reflectometer. Valid options are:

Code Description

0 None

C1 Control Port 1

C2 Control Port 2

3 Analog Channel 3

4 Analog Channel 4

5 Analog Channel 5

P_SW Analog Channel 6/P_SW

Mult, Offset: The Mult and Offset parameters are each a constant, variable,

array, or expression by which to scale the results of the raw measurement. A

multiplier value of 1 is recommended.

Program Description

1 Measure volumetric water content with 4 CS625 hourly. Store

average hourly readings to final storage every 4 hours.

2 Measure temperature with 109 probe and use the 109

temperature to correct the period for 1 CS625. Use standard

calibration equation to convert temperature-corrected period to

volumetric water content. Sensors are read hourly and average

water content and temperature are written to storage every 4

hours.
