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.

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:
