RF Considerations
The RF emissions are below FCC and EU limits as specified in
EN61326 if the CS616 is enabled less than 0.6 ms, and measure-
ments are made less frequently than once a second. External RF
sources can also affect the CS616 operation. Consequently, the
CS616 should be located away from significant sources of RF
such as ac power lines and motors.

Ordering Information
Water Content Reflectometer
CS616-L
Water Content Reflectometer with user-specified cable length.
Enter cable length, in feet, after -L. Recommended cable
length is 25, 50, 75, or 100 ft (8, 15, 23, or 31 m); maximum
length is 1000 ft (300 m). A cable termination option is
required (see below).
Cable Termination Options (choose one)
-PT
Cable terminates in pigtails for direct connection to the
datalogger’s terminals.
-PW
Cable terminates in a connector for attachment to a
prewired enclosure.
Installation Tool
CS650G
Rod Insertion Guide Tool with Pilot Rod
The CS650G makes insert-
ing CS616 easier in dense
or rocky soils. This tool can
be hammered into the
soil with force that might
damage the sensor if the
CS650G were not used.
It makes pilot holes into
which the rods of the sen-
sors can then be inserted.
