1.
Remove the locking pin from the suspension receiver by depressing the
barb and pulling the ring at the same time.
2.
Retract the spring sleeve on the suspension receiver and mate the ball stud
of the top-most sensor to the suspens0ion receiver by connecting them
together using a lateral motion.
3.
Release the spring sleeve to secure the ball stud inside the sleeve.
4.
Reinsert the locking pin to prevent the sleeve from retracting while in use.
2.5.3 LOWER THE TOP-MOST SENSOR
Lower the top-most sensor into the casing and position the suspension bracket
on top of the casing.
Important!
Ensure the top rim of the casing is relatively square to properly seat
the suspension bracket.
Readings may be taken immediately after installation, however,
GEOKON
recommends evaluating the data over a period of time to determine when the
string has sufficiently stabilized and when the zero readings should be
established.

Note:
The datalogger you use must have the appropriate port available.
If your datalogger does not have built-in RS-485 communications, connect
the wiring using the diagram to the left.
If your datalogger has built-in RS-485 communications, connect the wiring
